OIL AND GAS DEVELOPMENTS
ABSTRACT
Illinois produced 82,314,000 barrels of oil in 1956, a slight increase over the 1955 total
of 81,131,000, marking the third consecutive year of increased production after a 13-year
decline. Increased secondary recovery by waterflooding was the most important contribut-
ing factor. The 3,640 wells completed in 1956 represent a decrease of about 6 percent
from wells drilled in 1955. Forty five percent were successful completions. Seventeen new
oil pools, one gas pool, 81 extensions to pools, and 19 new pays were discovered in 1956.
The greatest activity was in the northern part of the productive area of the state.
Details of development and production are discussed by counties with special attention to
noteworthy areas. Reserves are estimated at 701.6 million barrels.
INTRODUCTION
The brief account of developments in
the oil and gas industry in Illinois during
1956, which appeared in "Statistics of Oil
and Gas Development and Production,"
issued annually by the American Institute
of Mining, Metallurgical, and Petroleum
Engineers, is herein expanded to provide
a more detailed discussion of the Illinois
petroleum industry. Developments are dis-
cussed by county, with special attention
given to noteworthy areas.
We gratefully acknowledge the coopera-
tion of the many oil companies and in-
dividuals who contributed basic data for
this report. The section on estimated pe-
troleum reserves was prepared by Lester
L. Whiting and Margaret Oros of the Illi-
nois State Geological Survey's Oil and Gas
Section and that on gas and gas products
by Whiting and Wayne F. Meents of the
same section. James Garrett and Jutta An-
derson, both of the Survey staff, also as-
sisted in preparing the report.
Compilation of the statistical data and
maps on waterflood operations in 1956 are
largely the work of Donald A. Pierre of the
Petroleum Engineering Section. They are
based on data furnished by the operators
through the Illinois Secondary Recovery
and Pressure Maintenance Study Commit-
tee of the Interstate Oil Compact Com-
mission.
PRODUCTION AND VALUE
Oil production in Illinois in 1956 was
82,314,000 barrels, a slight increase over
the 81,131,000 barrels produced in 1955.
The 1956 production was the highest for
any year since 1943. Peak production was
attained in 1940, after which production
gradually declined to a low of 59,025,000
barrels in 1953. In 1954 the trend was re-
versed and daily production increased
rapidly to a new but lower peak in June
1955. During the last half of 1955 and
throughout 1956, daily production re-
mained nearly constant (fig. 1 and table 1).
The upward trend in oil production
was caused by a big increase in secondary
recovery operations and a big increase in
drilling. Early in 1955 the Eldorado Con-
solidated pool contributed much to the
high production rate. During the last few
months of 1955 and throughout 1956 fewer
wells were drilled; the percentage of pro-
ducing wells fell off and initial produc-
tions were smaller.
Nevertheless, the continuing expansion
of secondary recovery operations was suf-
ficient to maintain the rate of production
throughout 1956, but cannot be expected
to do so indefinitely. The number of well
completions for 1956 (3,640) was the third
highest in Illinois history, but was 245
fewer than in 1955 (3,885). The decrease
in number of producing wells was from

d Figures in parentheses refer to number of producing wells included in totals which had previously been completed as dry holes.
2,164 in 1955 to 1,742 in 1956, a drop of
422 new producers. There were many good
wells in 1956 which had initial productions
of several hundred barrels, but none to
compare with the 3000- and 4000-barrel
wells in the Eldorado Consolidated pool in
1955.
Illinois continued to rank eighth in oil
production in the United States in 1955.
Daily average production lor the year was
almost 226,000 barrels. It is shown below

At the beginning of 1956, most of the
crude oii in Illinois was selling at $3.00
per barrel. During June and July, 10-cent
cuts were made by all of the major pipe-
line companies, bringing the price down
to $2.90 per barrel for the second half of

ILLINOIS STATE GEOLOGICAL SURVEY
the year. Value (at the wells) of crude oil
produced in Illinois in 1956 was about
$242,825,000. To this should be added the
value of natural gasoline and liquefied pe-
troleum gases extracted from Illinois nat-
ural gas, estimated at .$4,150,000, making a
total of $246,975,000.
DRILLING AND DEVELOPMENT
A total of 3,640* wells were drilled for
oil and gas in Illinois in 1956, (tables 1
and 2) a decrease of 6 percent from the
wells drilled in 1955. Of the 3,640 wells
completed, 1,596 were oil wells and 61 were
gas wells. Most of the gas wells were in the
Fishhook pool and were capped when
completed.
The successful wells completed in 1956
were about 45.5 percent of all wells drilled,
almost 10 percent less than in 1955. The
decreased percentage of successful wells is
attributed to the increase in wildcat drill-
ing in 1956. Although the total number of
wells drilled in 1956 decreased by 245, the
number of wildcat wells increased by 182.
Pool Development
Wells were drilled in 61 counties in 1956;
pool development drilling was done in 41
counties, and the other 20 counties had
only wildcat drilling (table 3).
There was no concentration of drilling
comparable to that in 1955, when White
County had 478 wells and Saline County
355. In 1956 Coles County led with 266
completions, followed by White, Douglas,
Wayne, Saline, and Crawford counties.
About 70 percent of the drilling was done
in 14 counties each of which had more
than 100 well completions.
Since 1942, when intensive drilling of
the Louden, Salem, and Centralia pools
ended, heaviest drilling has normally been
in the southern part of the structural basin.
The only exception was in 1946 when de-
velopment of the Mattoon pool resulted in
Coles County occupying first place in drill-
* Wall completion figures given in this bulletin are based on
reports received from the Illinois Basin Scout Association. An
undetermined number of additional wells are completed annually
in the old fields of Clark, Crawford, Cumberland, Lawrence,
and adjacent counties, for the most part in waterflooded areas.
ing in the state for the first time. Douglas
County, in third place, had its first produc-
ing well completed in 1955. The Coles-
Douglas County area is discussed on
p. 13.
Although the total number of well com-
pletions decreased in 1956, the distribution
was similar to that shown in 1955. For the
most part counties in the deeper and bet-
ter developed area of the basin showed
larger decreases than the over-all 6 percent
drop for the state; some of the decreases
exceeded 25 percent. Counties that had
major decreases in drilling activity in-
clude White, Gallatin, Saline, Hamilton,
Clay, Marion, and Lawrence.
Most of the marginal counties, on the
other hand, showed large increases, most
notable being Douglas County, which had
12 completions in 1955 and 248 in 1956.
Other counties that had major increases
in drilling activity include Edgar, Coles,
Moultrie, Shelby, Montgomery, Madison,
Clinton, Washington, Perry, Franklin, Wil-
liamson, and one deep-basin county,
Wabash. In many of these counties, pro-
duction is confined to a small geographic
area, and most of the increased drilling
was due to increased wildcat drilling.
Pools with the most producing wells
completed during the year were Cooks
Mills Consolidated with 190, Clay City
Consolidated with 180, and Main Consoli-
dated (Crawford County) with 102.
Several small pools (Oak Point in Clark
and Jasper counties, Harco in Saline Coun-
ty, Gards Point in Wabash County, and
Germantown East in Clinton County)
showed promise during the year, but drill-
ing in all of them tapered off before the
close of the year. When the year ended,
drilling and development had both slowed
down, and there was, at least temporarily,
no new area which exhibited especially
good prospects. As a result, wildcat drilling
was widespread.
Depths of producing wells drilled in 1956
ranged from about 400 feet to 4000 feet,
averaging about 2,365 feet; average depth
of all wells drilled in 1956 was about 2,145
feet.
DRILLING AND DEVELOPMENT
13
In fields discovered since January 1,
1937, there were 22,201 wells producing
oil or gas at the end of 1956; in older fields
the number was approximately 9,086, or a
total for Illinois of about 31,287 wells pro-
ducing at the end of 1956.
Cooks Mills — Bourbon Aria
The Cooks Mills pool in northern Coles
County was discovered in 1941. One pro-
ducing well was completed that year and
another the following year. Both produced
from the Rosiclare sandstone, had low ini-
tial productions, and were soon depleted.
The pool was abandoned in 1947, with a
total production of less than 6,000 barrels
of oil from the two wells.
In 1946 a third producing well was com-
pleted. This, the discovery well of the
Cooks Mills North pool, was a non-com-
mercial well which produced less than 500
barrels of oil from the Rosiclare before it
was abandoned in 1950.
The next producing well in the area was
drilled three years later, in 1953. This, too,
was a small Rosiclare well. The following
year two more producers were completed,
one in the Rosiclare and the other in the
Aux Vases sandstone. The three wells pro-
duced about 2,500 barrels of oil in 1954.
In the same year Cooks Mills East was dis-
covered, the discovery well being the only
completion before the end of the year.
In 1955 a drilling "boom" began which
resulted in the discovery of one more pool
in 1955, three pools in 1956, and the pro-
duction of 1,725,000 barrels of oil in the
area in 1956.
In July 1955, a Cypress gas well was com-
pleted between the old Cooks Mills and
Cooks Mills North pools. This, the discov-
ery well of the Cooks Mills Gas pool, was
soon offset by oil wells and incorporated
into the Cooks Mills Consolidated pool.
During 1955, 17 Rosiclare, one McClosky,
and one Aux Vases-Rosiclare oil wells, and
one Aux Vases and three Cypress gas wells
were completed in an area extending from
the old Cooks Mills North pool to south
of the old Cooks Mills pool. The wells were
scattered over an area 3i/9 miles long by a
mile wide, and infill drilling progressed
rapidly.
In January 1956, Cooks Mills East
crossed the Coles-Douglas County line, giv-
ing Douglas County its first commercial
production. Early in the year Cooks Mills
East was absorbed by Cooks Mills Consoli-
dated, which is now made up of Cooks
Mills, Cooks Mills North, Cooks Mills
Gas, and Cooks Mills East.
Early in the year the Bourbon pool was
discovered about six miles north of Cooks
Mills Consolidated, and a few weeks later
Bourbon North was discovered a little more
than a mile northwest of Bourbon. Later,
the Chesterville pool was discovered be-
tween Cooks Mills Consolidated and
Bourbon.
Bourbon is one of the biggest pools dis-
covered in the last few years. By the end
of 1956 it had produced almost half a mil-
lion barrels of oil from about 50 wells.
Chesterville (five wells) and Bourbon
North (two wells) were comparatively un-
important.
By the end of 1956 the Cooks Mills —
Bourbon area consisted of about 260 oil
wells which had produced 1,725,000 barrels
of oil during the year; 90,000 barrels had
been produced in the preceding 14 years.
About 250 oil wells were producing in the
four pools. Of this number all but three
were completed in the Rosiclare sandstone,
the exceptions being in the Cypress, Aux
Vases, and McClosky pays.
Fifteen gas wells have been drilled in
the Cooks Mills Consolidated pool: seven
were completed in the Cypress, one in the
Aux Vases, four in the Rosiclare, and three
as dual completions in the Cypress-Rosi-
clare. All were capped at the end of the
year, but plans were being developed for
a gas storage project in the pool.
The Cooks Mills-Bourbon area is the
northernmost Mississippian production in
the state, although Pennsylvanian sands
have produced a little oil to the northeast,
and several good Devonian and Silurian
pools lie to the northwest. As in the Mat-
toon pool, two miles to the south, the Rosi-
clare is the most important pay. Unlike
14
ILLINOIS STATE GEOLOGICAL SURVEY
Mattoon, where the Cypress is also an im-
portant pay, in the Cooks Mills-Bourbon
area only one oil well has been completed
in the Cypress, which more commonly car-
ries gas. The Aux Vases and McClosky are
unimportant pays in both areas, and other
possible pays are thus far unproductive.
As a result of the successful drilling in
the Cooks Mills-Bourbon area, there was
abundant and widespread wildcat drilling
in Douglas and Coles counties in 1956.
Occasionally shows of oil or gas were en-
countered, and one Pennsylvanian pool,
Ashmore East, was discovered in Coles
County. By the end of 1956 the Cooks
Mills-Bourbon area seemed to be almost
completely drilled up, and wildcat drilling
in Coles and Douglas counties was taper-
ing off.
Exploratory Drilling and Discoveries
Wildcat wells were drilled in all of the
61 counties in which drilling was done in
1956. New pools (18 in number) were dis-
covered in 11 counties. Douglas and Jeffer-
son counties each had three new pools;
Bond, Clinton and Saline counties each had
two, and Christian, Coles, Franklin, Ma-
coupin, Perry, and Wayne each had one.
Of the 3,640 wells drilled in 1956, 1,028
(about 28 percent) were wildcats, an in-
crease of about 12 percent in number of
wildcat completions over the number com-
pleted in 1955 and in contrast to the 6
percent decrease in total completions.
Of the wildcat wells drilled in 1956, 445
located more than two miles from pro-
duction (table 3) discovered 11 new pools,
or were about 2.5 percent successful. The
583 wildcats drilled between half a mile
and two miles from production discovered
seven new pools and 72 extensions to pools.
Nine additional extensions were discov-
ered by reworking old wells that had pre-
viously been completed as dry holes.

c Nine of the discovery wells listed in Table 4 were originally
completed as dry holes and later worked over.
The one gas pool and 17 oil pools dis-
covered in 1956 are listed in table 4 and
shown in figure 2; the 81 extensions are
listed in table 5, and the 19 new pays in
table 6. One of the new pools, Sorento
South, was lost by consolidation with
Sorento before the end of the year.
Most of the 1956 new pools, as shown in
figure 2, are marginal pools. The locations
of the 1955 new pool discoveries were great-
ly influenced by the 1954 developments,
nine new pools being grouped around El-
dorado Consolidated and five around Mt.
Auburn Consolidated. The 1956 discov-
eries show the same influence, but to a
lesser degree.
Three of the new pools (Ashmore East
in Coles County, Cravat East in Jefferson
County, and Hornsby South in Macoupin
County) produce from Pennsylvanian
sandstones. At the end of 1956 each con-
sisted of a single small well without pros-
pects for future development. Only one new
Pennsylvanian pay was discovered in 1956.
At the end of the year one Pennsylvanian
sandstone well was completed in the Soren-
to Consolidated pool (previously all De-
vonian production). This well is less than
four miles from Old Ripley, a good Penn-
sylvanian pool, so it may indicate the
presence of an oil-bearing Pennsylvanian
sandstone lens in the Sorento area.

Fig. 3. — Generalized geologic column for the southern Illinois oil region.
Black dots identify oil-producing strata.
Four Devonian or Silurian pools were
discovered. The best of them, German-
town East in Clinton County, had 21 wells
at the end of the year. Sicily, in Christian
County, had three producing wells com-
pleted, and other wells were being drilled.
The other two pools, both in Bond Coun-
ty, were Sorento West which was aban-
doned at the end of the year and Sorento
South which was consolidated with Soren-
to. The Silurian was also opened up as a
new deep pay in the Huev South pool in
Clinton County.
The Trenton was opened up as a new
pay in the Patoka and Irvington pools. At
the end of the year not enough Trenton
wells had been completed in either pool
to make possible an evaluation of the pay.
The remaining 11 new pools and 17
new pays were all in rocks of Mississippian
age.
A generalized geologic column for the
southern Illinois oil region indicating
principal producing strata, is shown in
figure 3.
A selected list of unsuccessful deep tests
in pools is given in table 7.
Xo gravity meter or magnetometer work
was done in Illinois in 1956. Data on geo-
physical and core-drilling crews operating
throughout the year, by months and
methods, is given in table 8.

acres and 16,460 gas acres were in pools
discovered since January 1, 1937. During
1956, 6,640 gas acres were added by 61 gas
wells, most of which are capped. In pools
discovered since January 1, 1937, about
16,690 surface acres for oil were added in
1956. Most of the drilling in the old pools
(discovered before 1937) was development
of new pays in old producing areas; little
surface acreage was added to the old pools.
ESTIMATED PETROLEUM RESERVES
The Illinois State Geological Survey esti-
mates that on January 1, 1957, Illinois oil
reserves that can be produced from wells
now in existence, by methods now in use,
total 701.6 million barrels. This represents
an increase of 0.3 million barrels over the
estimate for January 1, 1956. The factors
in this change are shown in the following
table:

The 1,694 oil producing wells, including
workover wells, completed during 1956
added an estimated oil reserve of 47.4 mil-
lion barrels, an average of about 27,878
barrels per well.
Of this 47.4 million barrels of added re-
serves, it is estimated that 2.0 percent is in
Pennsylvanian sandstone, 81.3 percent in
Mississippian sandstones and limestones,
and 15.8 percent in Devonian-Silurian
limestones and sandstones. New reserves
credited to the Ordovician totaled less than
1 percent.
The most important pay zones for which
new reserves were added by 1956 drilling
are the Ste. Genevieve limestones and sand-
stone with 31.6 percent of the new reserves,
the Aux Vases sandstone with 30.1 percent,
and the Devonian-Silurian limestones and
sandstones with 15.8 percent. Other im-
portant pay zones are the Cypress sand-
stone with 9.1 percent, and the Bethel
sandstone with 5.6 percent. Pennsylvanian
sandstones contributed 2.0 percent, and
Mississippian pays other than those listed
above contributed 5.0 percent.
The Devonian-Silurian formations with
15.8 percent new reserves in 1956 have
materially increased in importance during
the last three years. The percentage figures
for these formations were 5.9 in 1954 and
9.6 in 1955.
The reserves added by the 17 new oil
fields discovered during 1956 are estimated
at 5,209,000 barrels of oil. A breakdown
of this total by pays shows Devonian-
Silurian formations in the lead with 60.8
percent, followed by the Ste. Genevieve
formation with 32.0 percent, Aux Vases
with 5.2 percent, and the Cypress with 1.0
percent. The other 1.0 percent is scattered
among the remaining pays in the Chester
and Pennsylvanian formations.
The principal changes indicated are in
the Devonian-Silurian for which the new
pool reserves rose from 49 percent of the
total in 1955 to 61 percent in 1956. This
was mainly at the expense of the Chester
series for which new pool reserves dropped
from 21 percent in 1955 to 7 percent in
1956.
The four Devonian-Silurian discoveries
are all in R. 4 W. They extend from T.
1 N., in Clinton County, to T. 13 N. in
Christian County. The Rosiclare sandstone
discoveries, which account for 30 percent
of the 32 percent new reserves attributed
to the Ste. Genevieve formation, are all in
Douglas County. Jefferson County had
three new pools, with production from
Pennsylvanian and Aux Vases sandstone
and the McClosky limestone.
On January 1, 1957, Illinois had about
380 producing oil pools. Three of these
(Clay City Consolidated, Louden, and
Salem Consolidated) had estimated reserves
of 378.6 million barrels or 54 percent of
the 701.6 million barrels reserves.
Ten pools, including the above three,
had estimated reserves of more than 10
million barrels each, for a total of 521.8
million barrels, or 74.3 percent of the total
oil reserves.
Approximately 320 pools had reserves
of less than one million barrels each. Their
total estimated reserves of 43.1 million bar-
rels was approximately 6 percent of the
total reserves.
PROSPECTS FOR NEW POOLS
An average of 25 to 35 new pools has
been discovered in Illinois annually for
about 20 years. In 1956 only 18 new pools
were discovered, and the number may con-
tinue to be smaller than in the past. As
productive areas are drilled up, discovery
wells are more apt to be extensions of
pools rather than discovery wells of new
pools.
Figure 4 is a map of the state that classi-
fies oil and gas possibilities by areas. The
map is slightly modified after a similar
classification map prepared by the Survey
in 1930, seven years before oil was discov-
ered in the deep part of the basin (out-
lined by the dashed line in fig. 4).
From 1937 to 1954 most of the new pools
discovered were in the deeper part of the
basin and produced from Pennsylvanian
and Mississippian pays. Outstanding ex-
ceptions include two marginal pools, Ma-
rine with Devonian-Silurian production

and St. Jacob, a Trenton pool, and, in
the deep part of the basin, the Devonian
and Trenton in the Salem Consolidated
and Centralia pools. In these two latter
pools, however, Mississippian pays were
first discovered and developed and the
deeper pays were found by deepening wells
within the pools.
Many of the counties in the deeper part
of the basin, such as Wabash, Wayne,
White, and Edwards, have been developed
to an extent allowing little possibility for
finding new pools. Only one of the 1956
new pools was in this area. In 1954, 1955,
and 1956 most of the new pools were near
the margin, or outside the deeper part of
the basin. In these three years there has
been a great increase in number and rela-
tive importance of new Devonian and
Silurian pools.
At the end of 1956 new Trenton pays
were discovered in the Irvington and
Patoka pools, both fairly close to the good
Trenton production in Salem Consolidated
and Centralia. Tests of the Trenton and
Devonian are rare in deeper parts of the
basin. In most counties testing of the Salem
and St. Louis limestones has also been
limited to only a few wells.
In the past all but a very small percent-
age of Illinois' oil production has come
from Pennsylvanian and upper Mississip-
pian rocks. Results of drilling in the last
three years suggest that pre-Mississippian
rocks warrant further testing.
GAS AND GAS PRODUCTS
An estimated 32 billion cubic feet of gas
was produced from Illinois oil wells dur-
ing 1956, either as solution gas or in sepa-
rate gas reservoirs in the oil areas.
Most of the 110.7 million cubic feet of
dry gas marketed in Carmi and Eldorado
was obtained from dry gas wells within oil
fields. An additional 683.1 million cubic
feet of dry gas from oil wells was delivered
to gas pipe lines for distribution through-
out the state. Details are shown in the
chart given below.
About 7.2 billion cubic feet of solution
gas from Illinois oil wells was processed
during 1956 by the three principal operat-
ing companies, with the resultant produc-
tion of 1,660,000 barrels of natural gasoline
and allied products. This figure does not
include natural gasoline and allied prod-
ucts produced at one plant in Illinois
which processes gas from outside the state.
Data furnished by the companies indicate
that approximately 469.1 million cubic feet
of dry residue gas was returned to the pro-
ducing formations, the remainder being
used as plant or lease fuel. The amount of
plant residue gas flared was insignificant.
In addition to the 7.2 billion cubic feet
of metered solution gas processed, a some-
what smaller amount of unmetered gas was
used largely for lease fuel. Between 20 and
25 billion cubic feet of gas was flared dur-
ing the year, principally in the Saline Coun-
ty area.
Sixty-one new gas wells located in eight
different pools in nine different counties
were completed during 1956. None of the
gas has been marketed for use away from
the producing area.
Two of the eight pools in which this
gas is found are the Fishhook pool in Pike
and Adams counties, which has produced
only gas to date, and the Cooks Mills Con-
solidated pools in Coles and Douglas coun-
ties, which produces both gas and oil. One
of the major gas suppliers to the northern
part of the state is currently installing pipe-
lines in this field for the dual purpose of
using the presently available gas and even-
tually using the structure as a storage
reservoir.

OIL PRODUCING STRATA OF
ILLINOIS
51 l FIG. 3, PAGE 17)
Oil production from sandstones in the
upper two groups of Pennsylvanian age, the
McLeansboro and Carbondale groups, is
very minor; Tradewater and Caseyville
sandstones have yielded about one-sixth of
the state's oil. The original low gas content
of many Pennsylvanian oils resulted in
rather low primary recovery and together
with shallow depth makes the Pennsylva-
nian reservoirs particularly attractive for
secondary recovery. Despite the fact that
little oil has been found in the Pennsyl-
vanian in the last few years, Pennsylvanian
production has been increasing, owing to
the development of secondary recovery
projects.
Chester sandstones have to date pro-
duced more than one-half of Illinois' oil
and the proportion is mounting. The
higher sandstones, the Degonia, Clore, and
Palestine, are of little consequence and are
productive only in the region of the lower
Wabash Valley. The middle sandstones,
Waltersburg, Tar Springs, and Hardins-
burg, are more productive with some very
prolific pools, but significant accumula-
tions are confined to a relatively small area
in the southern and eastern oil counties.
The lower Chester sandstones in gen-
eral, and the Cypress and Aux Vases in
particular, are productive nearly through-
out the oil country.
The high water content of the Aux
Vases makes oil more difficult to recognize
than in other sandstones, and Aux Vases
production was sometimes passed by dur-
ing the earlier stages of exploration. Fine-
grained reservoirs react spectacularly to
hydraulic fracturing. Although the Aux
Vases has produced less oil in the past than
the Benoist (Bethel) and Cypress sands, it
is probably leading in current production
and is by far the most important single
horizon in current development.
The most prolific reservoirs in the lower
Mississippian rocks are oolitic limestones,
which have produced one-fifth of Illinois'
oil. Most important is the McClosky zone,
which consists of porous lenses of oolitic
limestone in the Fredonia member of the
Ste. Genevieve formation. The oolitic
Ohara pay zone in the Levias member of
the Ste. Genevieve is quite similar to the
McClosky, as are oolites in the St. Louis
and Salem formations. Hydraulic fractur-
ing of the oolitic reservoirs is not particu-
larly helpful, but in most instances produc-
tivity can be increased greatly by acidizing.
Waterflooding is simple, but as primary re-
covery is generally high, less oil is left for
secondary recovery than in the sandstone
reservoirs.
The Rosiclare zone is a typical oolite in
the southern and eastern oil counties, with
occasional sand grains accompanying the
oolites. Toward the northwest the sand
grains become more numerous and produc-
tion is obtained from a slightly limy sand-
stone, a bit coarser than the average Ches-
ter sandstone.
Devonian production comes from sand-
stones, limestones, dolomites, and cherts,
and is difficult to characterize briefly.
Silurian production, approaching one
percent of Illinois' total, is from two quite
different types of rock. Much Silurian
dolomite in the southern part of Illinois is
too fine-grained for production, but occa-
sional streaks, generally purer, are coarse
enough to approach the lower limit of pro-
ductive dolomite rock. As might be ex-
pected, this fine-grained rock reacts favor-
ably to fracturing but poses problems in
waterflooding. Silurian "coral" reefs in the
northern part of Illinois are dolomitized,
porous, and very permeable. In the oil
area the reefs are limestone with very low
porosity but have a few vugs and an ex-
tensive fracture system that may contain
oil. Silurian reef rock produces oil from
Marion County westward.
The Trenton limestone has produced
less than one percent of Illinois' oil. The
limestone generally is quite dense. Porosity
and permeability increase westward across
the western part of the oil area, and frac-
tures are of considerable importance in the
westernmost pools. Acidizing is a common
completion practice, and it seems likely
that hydraulic fracturing will be of rela-
tively little help.

Adams County has had no commercial
production of oil or gas. The first pro-
ducing well in the county was a small
gas well completed in 1955 in the Fishhook
pool. In 1956 four more gas wells were
completed; initial open flow capacities
ranged from 46,000 cu. ft. daily to 2,000,000.
These wells are in a Silurian limestone
about 500 feet deep. They are in the Fish-
hook pool, most of which lies to the east
in Pike County. All wells in the pool have
been capped. The Fishhook pool may be
used for gas storage.
The five dry holes drilled in 1956 in-
cluded one dry hole in the Fishhook pool
and four wildcats. No successful oil well has
yet been drilled in Adams County.
Bond County
Fig. 22, Area 17
As shown in the table, Bond County pro-
duced more oil in 1956 than in any pre-
vious year, in fact 1956 production was al-
most a third of the total production to
date for the county. Most of the producing
wells drilled in 1955 were completed near
the end of the year and still had compara-
tively high production rates in the early
months of 1956. Most of the producing
wells drilled in 1956 were completed early
in the year and production had declined
by the end of the year. Unless drilling re-
sults are better in 1957 than in 1956, pro-
duction for 1957 will probably be less than
in 1956.
In number of wells drilled, 1956 was sec-
ond only to 1955 and far surpassed the
third best year, 1950. However, only a third
of the wells drilled in 1956 were completed
as producers. Of the 84 dry holes com-
pleted, 41 were in pools and 43 were wild-
cats. Of the wells drilled in pools, 50 per-
cent were dry, a very low success ratio.
Bond County was one of the counties
which had an unusually high rate of wild-
cat drilling in 1956. Discoveries in pre-
Mississippian pays during 1954 and 1955
increased interest in the possibilities of
deep production in the counties along the
western margin of the deep basin area.
Two new pools discovered in 1956 are pro-
ducing from a sandstone at the top of the
Devonian. One, Sorento West, consisted of
a single well which was abandoned at the
end of the year. The second, Sorento South,
expanded rapidly and was consolidated
with Sorento before the end of 1956.

ILLINOIS STATE GEOLOGICAL SURVEY
Two new pays were discovered in Bond
County in 1956. In Sorento Consolidated
Pennsylvanian sandstone production was
opened up, and in Woburn Consolidated
two Aux Vases wells were completed, the
first Aux Vases production reported in the
county.
Although Bond County has had 11 oil
or gas pools, as shown on the county map,
most of the oil has come from two pools:
Woburn Consolidated, which produced
614,000 barrels in 1956 for a total of 2,-
455,000 barrels, and Sorento Consolidated,
which produced 419,000 barrels for a total
of 639,000 barrels.
Only three other pools had production
reported for 1956. Old Ripley produced
48,000 barrels to make a total of 102,000;
Beaver Creek, 8,000 barrels for a total of
179,000, and Dudleyville East, a few hun-
dred barrels for the year and a total pro-
duction of about 2,000 barrels.
Bond County has one secondary recov-
ery project. A small waterflood in the
Bethel in the Woburn Consolidated pool,
begun in 1951, has produced about 11,000
barrels of oil. A pressure maintenance
project, begun in 1953, is credited with 14,-
000 barrels of oil produced in the Beaver
Creek pool.
Christian County
Fig. 18, Area 13
Drilling activity in Christian County in
1956 was a little less than in 1955, but re-
mained higher than average for the county.
Most of the new producing wells were in
the Mt. Auburn — Kincaid — Edinburg West
area. One new pool, Sicily, was discovered
during the year; three producing wells
were completed in it.
The percentage of successful wells for
the county was low because of the large
number of wildcat wells drilled. Twenty-
nine producing wells and 16 dry holes were
drilled in pools, a success ratio of about
2 to 1. Unsuccessful wildcats numbered 39.
Production for the year set a new rec-
ord. Eleven pools produced a total of 1,-
846,000 barrels of oil. Biggest producer was
the Kincaid South pool, which made 810,-

000 barrels for the year, giving it a total
production of 885,000 barrels. Assumption
Consolidated was second for the year, pro-
ducing 342,000 barrels; it has a cumulative
total of 5,384,000 barrels. Three other pools
each produced 200,000 to 235,000 barrels,
and the remaining six pools had a com-
bined total production of 32,000 barrels.
Secondary recovery has been important
in maintaining production in Christian
County. The first waterflood project in the
county was in the Benoist sandstone in the
Assumption Consolidated pool. In general
the Benoist wells in the pool were not as
good as the Rosiclare wells, and were much
more restricted in area than the Devonian
wells.
Waterflooding began in 1950; by the end
of 1956 it had produced 858,000 barrels from
the Benoist sand, more than 10 percent
of all of the oil produced in the county.
In 1955 waterflooding of the Rosiclare
sandstone and Devonian limestone was be-
gun. Only a small amount of secondary re-
covery oil has so far been produced from
these two pays. However, in 1956, 188,000
barrels of the 342,000 barrels produced in
the Assumption Consolidated pool was at-
tributed to secondary recovery, mainly from
the Benoist. Total secondary recovery pro-

duction for the pool is 925,000 barrels,

tion lor the county. It results ol flooding
the Rosiclare and Devonian are comparable
to the Benoist Hood, secondary recovery

Clark and Cumberland were among the
early oil producing counties, production
dating back to 1904. It is impossible to
break down the old production accurately
between the two counties, so they must
be treated as a unit. Many of these old
pools are being waterflooded. Wells drilled
in the waterflood areas are not included
in the above tables.
Clark County has two good pools dis-
covered since 1937, Weaver and Oak Point.
Twelve of the producers drilled in 1956
were in the Oak Point pool. The 38 dry
holes include 15 in pools and 23 wildcats.
Most of the Cumberland County "new
pool" production comes from the Lilly-
ville pool. There were no producing wells
drilled in Cumberland County in 1956 out-
side of waterHood projects. The 1 1 dry
holes included four in pools and seven
wildcats.
Secondary recovery is very important in
maintaining the level of production in the
old pools of Clark and Cumberland coun-
ties. In 1956, 1,587,000 barrels of oil out of
the 1,880,000 barrels produced were the re-
sult of waterHooding. Some of the projects
are new, and others are being developed.

Clay City Consolidated and the rest of the
pools in the county. Forty-six of the dry
holes were drilled in pools and 12 were
wildcats.
Clay is one of the counties which showed
the biggest decreases in drilling in 1956, a
much bigger decrease than that for the
state as a whole. There has never been a
period of intensive drilling in the county,
but it has annually ranked among the top
dozen or so in number of completions. As
a result, it is one of the most extensively
drilled counties, and new pools of conse-
quence are not apt to be found. However,
only a few wells have tested pre-Mississip-
pian strata in the county. The best hope
for the future in Clay County lies in the
discovery of profitable deep pays.
Secondary recovery projects are in opera-
tion in five pools in Clay County. All are
small or quite recent. The Ingraham pool
flood was begun in 1956, and had not
shown any results at the end of the year.
The other four pools with waterflood proj-
ects (Clay City Consolidated, Kenner West,
Sailor Springs Consolidated, and Stanford
South) produced 408,000 barrels of second-
ary recovery oil, less than 10 percent of the
county's production for 1956. Cumulative
secondary recovery oil production is about
1,037,000 barrels.

Two new pools were discovered in
Clinton County in 1956. One, Germantown
East, was the second best discovery of the
year according to drilling and production
by the end of the year; only Bourbon in
Douglas County surpassed it. By the end
of the year the 21 completed wells had
produced 329,000 barrels of oil from the
Devonian, and other wells were being
drilled. Clinton County is in the part of
the state where the Devonian, Silurian, and
Trenton pays have produced the most oil.
It should be possible to discover more
new pools like Germantown East.
The second new pool was Beckemeyer
Gas. Two gas wells and one oil well were
completed by the end of the year. The two
gas wells were capped and the oil well had
not sold any oil. All three were Cypress
sandstone wells.
Twenty-four of the 29 producing wells
drilled in 1956 were in the two new pools,

23 of the 70 dry holes were pool dry holes,
and the other 47 were wildcats.
Secondary recovery projects are in opera-
tion in two pools in Clinton County. The
first project began in 1952 in the Bartelso
pool. In 1956 the three floods operating in
that pool produced 217,000 of the 356,000
barrels produced from the pool. Water-
flooding was begun in the Centralia pool in
1956 and produced 136,000 barrels of oil
in the first year. About 800,000 barrels of
oil has been produced in Clinton County
by secondary recovery operations.
were opened up in the old producing
areas, and Crawford County has been one
of the most active drilling counties for the
past three years.
Secondary recovery by means of both gas
and water has been tried in Crawford
County, but water injection has proved
more satisfactory than gas. The steady in-
crease in production since 1950 must be
attributed to secondary recovery. In 1956,
1,887,000 barrels, or two-thirds of the pro-
duction for the year, resulted from water-
flooding.

Although few Illinois counties have pro-
duced as much oil as Crawford County,
most of the drilling and production oc-
curred during the 30 years preceding 1937.
During that period about 9,000 producing
wells were drilled and 140,390,000 barrels
of oil were produced as compared with
525 oil and gas wells drilled in the past 20
years, and 32,233,000 barrels of oil pro-
duced.
When the deep basin was opened up in
1937, there had been little drilling in Craw-
ford County for 10 years, and production
was dropping. In 1954 several new pays
As shown in the table, 1956 was the sec-
ond biggest year for oil well drilling in
Coles County, due to the development of
the Cooks Mills area. This development is
discussed on page 13. The biggest year of
drilling was 10 years earlier when the
Mattoon pool was being developed. Out-
side of these two pools, Coles County has
no significant production. Westfield North
produced less than 1,000 barrels before it
was abandoned. Ashmore East, a one-well
Pennsylvanian sandstone pool discovered
in 1956, had had no pipeline runs at the
end of the year. Two old pools are mainly
in other counties, and their production is

assigned to those counties. They are War-
renton-Borton, which is included in Edgar
County production, and Westfield, in-
cluded with Clark County.
Until 1956 the Mattoon pool produced
almost all of the Coles County oil. It has
produced a total of 12,248,000 barrels of the
13,340,000 barrels produced in the county.
Waterflooding was begun in 1950 in the
Rosiclare sandstone, and a second project
was begun in 1952 in the Cypress and Rosi-
clare pays. Secondary recovery is credited
with a total of 551,000 barrels of oil, in-
cluding 332,000 barrels of the 635,000 bar-
rels produced in 1956.
The Cooks Mills Consolidated pool pro-
duced 1,001,000 barrels of oil in Coles
County in 1956, bringing its total produc-
tion up to 1,092,000 barrels.

Prior to 1956 very little testing for oil or
gas had been done in Douglas County. The
nearest production of economic value was
about 10 miles to the south in the Mattoon
pool. A few producing wells had been
drilled closer to the county line, but none
had produced oil in commercial quantity.
The Murdock pool in Douglas County, dis-
covered in 1955, is a single Pennsylvanian
sandstone well which has produced only a
few barrels of oil.
Toward the end of 1955 good Rosiclare
sandstone production was found in the
Cooks Mills area in northern Coles County.
Early in 1956 the Cooks Mills Consolidated
pool was extended into Douglas County.
Three more pools — Bourbon, Bourbon
North, and Chesterville — were discovered
in 1956, all of them a short distance north
of Cooks Mills Consolidated in Douglas
County. One of these pools, Bourbon, was
the best pool discovered in 1956. It had 50
producing wells at the end of the year and
had produced almost half a million barrels
of oil. The Cooks Mills-Bourbon area is
discussed in more detail on page 13.
Of the 248 wells drilled in Douglas
County in 1956, only 107 were successful.
However, only 52 of the dry holes were in
pools, giving a success ratio of 2 to 1 for
pool drilling. The other 89 dry holes were
wildcats. Some of them had fairly good
shows of oil, but Bourbon lies close to the
northern edge of the part of the state hav-
ing the best possibilities for oil.

COUNTY RETORTS
53
Edgar is one of the counties which had
big increases in drilling in 195() in contrast
to the over-all decrease. Because of the
county's proximity to the Cooks Mills —
Bourbon area, an increase in wildcat drill-
ing might have been expected. However,
most ol the drilling was in pools. Five small
producing wrells were completed, lour in
Grandview and one in Inclose, 19 dry holes
were drilled in pools, and only 10 of the
34 wells drilled in 1956 were wildcats.
Oil produced during 1956 included
64,000 barrels from the Dudley pool, 50,000
from Elbridge, and insignificant amounts
from Inclose, Grandview, and Warrenton-
Borton pools.
Two pools, Redmon North and Dudley
West, consist of one gas well each, and
Grandview and Inclose are essentially gas
will probably be small. In 1956 there was
no area of concentrated drilling. The 28
new producing wells were distributed, for
the most part, one or two to a pool; no
pool had more than half a dozen. The 42
dry holes included 31 in pools and 11
wildcats.
Waterfiooding and pressure maintenance
are being used effectively in the Albion Con-
solidated pool. Waterffooding is also being
used in Maplegrove Consolidated and
Samsville North, and pressure maintenance
in Bone Gap Consolidated. In 1956, 422,-
000 barrels of oil, more than one-fourth
of the year's production, was recovered by
secondary recovery operations. Over 2,000,-
000 barrels of the county's total production
is attributed to secondary recovery.

54
ILLINOIS STATE GEOLOGICAL SURVEY
both of which have most of their wells and
production in Clay County. A small area
of the Louden pool extends from Fayette
County into Effingham.
At present Iola Consolidated has the
highest production rate in the county.
Eleven of the 13 producing wells completed
in 1956 were in the Iola Consolidated pool,
which produced 188,000 barrels for the
year, bringing its total production to 2,-
863,000 barrels.
Sailor Springs Consolidated produced
only 98,000 barrels in 1956, but has a total
production of 3,291,000 barrels. The only
secondary recovery operations in Effingham
County are in this pool. Four waterflood
projects, all in the Rosiclare or McClosky,
were begun in 1954 and 1955. In 1956,
33,000 barrels, about one-third of the year's
production, was due to waterflooding.
About 50,000 barrels of oil has so far been
produced in this way.
Hill East, the largest pool lying wholly
in Effingham County, had a 1956 produc-
tion of 187,000 barrels, bringing its total
up to 462,000 barrels.
Eleven of the dry holes drilled in 1956
were in pools and 14 were wildcats. No
new pool or important new pay was
discovered.
Fayette County
Fig. 16, Area 11
Fayette is one of the few counties in the
state in which oil wells outnumber dry
holes. During 1938, 1939, and 1940, when
Louden and St. James pools were being
developed, about 90 percent of all wells
drilled were producers. Annual comple-
tions for the entire state usually show a
majority of the holes to be dry. Fayette
County had a second period of intensive
drilling in 1950 during which an exten-
sion to the Louden pool was drilled up.
Except for these two periods, Fayette has
had few wells drilled and most of them
have been unsuccessful. Of the 29 wells
drilled in 1956, nine were producers, eight
were dry holes in pools, and 12 were un-
successful wildcats.

Three of the five pools in Fayette Coun-
ty are small. St. Paul, Patoka West, and
Laclede had a combined production of
about 25,000 barrels in 1956, and a total
production of less than 1,000,000 barrels of
oil.
A secondary recovery project by water-
flooding was begun in the St. James pool
in 1954. Only nine producing wells are
included in the project, so the amount of
oil produced by this method is compara-
tively small. Only 25,000 of the 406,000 bar-
rels produced in 1957 are attributed to sec-
ondary recovery, and only 80,009 barrels of
the pool's total production of about 13,-
743,000 barrels of oil is so classified.
Pressure maintenance was used in the
Louden pool from early in the pool's de-
velopment. In 1950 one waterflood project
was begun. Others have been or are being
started, including five new floods in 1956.
Flooding has been confined to the Chester
(Mississippian) sands; pressure mainte-
nance is still used in the Devonian. In 1956,
Louden produced 9,928,000 barrels of oil,
of which 7,694,000 barrels were attributed
to waterflooding or pressure maintenance.
These same operations are credited with
30,950,000 barrels of the total production
of 197,968,000 barrels of oil from the
Louden pool.

Drilling was

widespread; 12 of the 40 new oil wells
completed were in the Akin pool, 11
were in the West Frankfort pool, and most
of the others were distributed one or two
to a pool.
Of the 44 dry holes, 23 were in pools
and 21 were unsuccessful wildcats. One new
pool was discovered, Ewing East, which
had not run any oil at the end of the
year.
The Benton pool produced 1,050,000 bar-
rels of oil in 1956, slightly more than half
of the production for the county. The total
for the pool on January 1, 1957, was 32,-
708,000 barrels or about three fourths of
the county's total production. Secondary
recovery has probably been more impor-
tant in the Benton pool than in any other
pool in the state except possibly Salem
Consolidated and Louden. In 1949 when
waterflooding began, annual production
had dropped to 511,000 barrels; in 1956
Gallatin is one of the counties that had
the biggest decrease in drilling in 1956,
but drilling was so far above normal in
1955 that in spite of a decrease of more
than 25 percent, 1956 was the fourth high-
est drilling year for the county.
Most of the new producing wells were
in either Roland Consolidated (37 wells)
or Inman East Consolidated (19 wells).
Forty-three of the dry holes were drilled in
pools, and 20 were wildcats.
Secondary recovery operations are wide-
spread and successful. Four pools, Inman
East Consolidated, Inman West Consoli-
dated, Junction, and Roland Consolidated,
have waterflood projects, and Omaha has
pressure maintenance. More than half of
the 1956 production (1,687,000 barrels) is
the result of secondary recovery operations,
and almost 20 percent of the county's total
production (5,121,000 barrels).

Most of the pool wells drilled in Hamil-
ton County in 1956 were in the Dale Con-
solidated pool, and most of the new pro-
duction is from the Aux Vases sandstone.
A total of 57 producing wells, 51 of them
in the Aux Vases, were completed in Dale
Consolidated and 15 Aux Vases and six
Renault wells in Bungay Consolidated. The
81 dry holes include 58 pool wells and 23
wildcats.
Secondary recovery operations are in ef-
fect in the two biggest pools in the county.
Dale Consolidated, which has produced
and is currently producing about three-
fourths of the Hamilton County oil, has
four small waterflood projects; their 1956
production was only 157,000 barrels out of
3,018,000 for the pool for the year.
In Bungay Consolidated an Aux Vases
Hood produced 202,000 barrels in 1956, or
more than 25 percent of the pool's produc-
tion for the year which amounted to 792,-
000 barrels.
Oil production in Hancock and Mc-
Donough counties is from a single pool,
Colmar-Plymouth, and cannot be divided.
The pool was discovered in 1914. A total
of 497 producing wells have been drilled
in the two counties, 463 of them before
1937, and more than half of the oil pro-
duced was produced before 1937.
In the 20 years since the deep basin was
opened up, there has been little drilling in
Hancock or McDonough counties. The
eight wells completed in 1956 include one
oil well, one pool dry hole, and three wild-
cats in McDonough County and one pool
dry hole and two wildcats in Hancock
County.
Jackson County
Fig. 23, Area 18
Results of drilling in Jackson County
have not been encouraging. Only two of
the 55 wells drilled in the past 20 years
have been completed as producing wells,
and it is doubtful that either will be eco-
nomically successful.

Ava— Campbell Hill, older of the two
pools in the county, was discovered in 1916
and abandoned in 1943. It had both oil and
gas wells but produced little of either. In
1956 a Cypress oil well was completed,
which revived the pool, but no production
was reported for 1956.
The Elkville pool consists of a single well
drilled in 1941 which has produced about
4,000 barrels of oil. No production has
been reported since 1951.
Jasper County
Fig. 13, Area 8
No new pool was discovered in Jasper
County in 1956, but the Oak Point pool
expanded from Clark County into Jasper
County, and the first production in Jasper
County from Sailor Springs Consolidated
was reported, from a well drilled in 1955.
Thirteen Aux Vases sandstone oil wells
were completed in the Jasper County por-
tion of Oak Point and eight McClosky
wells in Ste. Marie West. Most of the other
wells among the 62 producing wells com-
pleted in the county in 1956 were in Clay
City Consolidated. The 62 dry holes in-
clude 30 in pools and 32 wildcats.
Four pools in the county have waterflood
projects: Clay City Consolidated, Dundas
East, Ste. Marie and Willow Hill East.
The Ste. Marie waterflood began in 1948,
one of the early ones in the deep basin.
In 1956 secondary recovery projects pro-
duced 207,000 barrels of oil, about 10 per-
cent of the county's production for the
year. About 600,000 barrels of oil have
been recovered by secondary recovery
methods.

Three new pools, Cravat West, Mt. Ver-

in Jefferson County in 1956. Cravat West
had had no commercial production from
its two Pennsylvanian wells at the end of
the year. Mt. Vernon North was a one-well
McClosky pool which produced about 5,-
000 barrels of oil. Oakdale had four Aux
Vases and two McClosky wells which had
produced 61,000 barrels of oil.
Divide West had more producing wells
drilled in 1956 than any other pool in the
county. Thirteen Ste. Genevieve and four

St. Louis wells were completed. The 54 dry
holes included 31 in pools and 23 wildcats.
Waterfloods were begun in two Jefferson
County pools in 1954 and in two more in
1955. Results are most apparent in the Boyd
pool, where 353,000 barrels of the 936,000
barrels produced in 1956 are from water-
flooded leases. Other secondary recovery
projects have been in operation too short
a time to have been very effective.
Pressure maintenance has been practised
in the old Dix area of the Salem Consoli-
dated pool for many years. In 1956 it was
credited with 437,000 barrels of the 445,000
barrels produced in the Jefferson County
part of the pool. Cumulative pressure main-
tenance production is 7,993,000 barrels of
the total 8,435,000 barrels for the pool.
Lawrence County
Fig. 9, Area 4
Lawrence County has produced more oil
than any other county except Marion. How-
ever, half a dozen counties are currently
outproducing it and will probably pass it
in the next few years. Oil was discovered in
Lawrence County in 1906; in the following
30 years about 4/5 of the producing wells
which have been drilled in the county were
completed, and about 4/5 of the total oil
production had been produced. Total pro-
duction from the new pools is less than
annual production from the old Lawrence
pool.

The remaining 96 were in the old Law-
rence pool. Most of these were drilled to
new pays in areas of old production. The

seven wildcats.
Secondary recovery operations are an im-
portant factor in maintaining production
in Lawrence County. Projects now in oper-
ation in the old Lawrence pool have pro-
duced 8,624,000 barrels of oil, including
2,526,000 barrels in 1956, 55 percent of the
pool's production for the year.

producing well was drilled in the Oakley
pool in 1956 and one former dry hole was
worked over into a producer in the Harris-
town pool.
Two of the 13 wells drilled in 1956 were
dry holes in pools and 10 were unsuccessful
wildcats. Shows of heavy oils are fairly com-
mon in Macon County, but there has been
little production except in the Blackland
pool which is in the extreme southern part
of the county and extends into Christian
County. The Macon County part of the
pool produced 65,000 barrels in 1956, for a
grand total of 236,000 barrels.
Three smaller pools, Decatur, Harris-
town, and Oakley, had a combined produc-
tion for the year of 7,000 barrels. The only
other pool, Decatur North, was abandoned
in 1955.
Macoupin County
Fig. 20, Area 15
Although oil was discovered in Macou-
pin County in 1909, the amount of oil
which has been produced is insignificant.
Data are incomplete because most of the oil
has not been marketed through pipe lines,
but production has probably averaged less
than 1000 barrels per year. In 1956 known
production was less than 500 barrels.
One new pool, Hornsby South, was dis-
covered in 1956. The discovery well was
completed in late November with an initial
production of nine barrels of oil and nine
of water per day from a Pennsylvanian sand-
stone. No more wells were drilled and no
oil marketed before the end of the year.
The 14 dry holes drilled in 1956 included
three in pools and 1 1 wildcats.
Madison County
Fig. 22, Area 17
Results of drilling in Madison County
during the past few years have been very
poor. In 1956, 42 wells were completed.
These included three small Pennsylvanian
sand oil wells in Livingston and Livingston
South, one small Pennsylvanian sand gas
well which was drilled as a wildcat and
capped when completed, 8 dry holes in
pools, and 30 unsuccessful wildcats.
The Marine pool, producing from the
Devonian and Silurian, is the biggest pool
in Madison County. It had a 1956 produc-
tion of 297,000 barrels, making its total
9,568,000 barrels, about 72 percent of the
total production for the county. St. Jacob
produced 61,000 barrels from the Trenton
in 1956, to bring its total up to 2,862,000

barrels or 22 percent of the county total.
The remaining 6 percent is Pennsylvanian
oil from Livingston and Livingston South
pools.
Secondary recovery is unimportant at
present in Madison County. Two projects
were started in the Livingston pool, one in
1952 and one in 1954. Only 3,000 barrels of
oil has been recovered by waterflooding.
Marion County
Fig. 17, Area 12
Marion County has produced more oil
than any other Illinois county. However,
more than 50 percent of the oil was pro-
duced during a 4-year period, 1938 through
1941, when Salem and Centralia were be-
ing developed. About 80 percent of the pro-
ducing wells in the county were drilled in
the same period.
Eight of the 30 producing wells com-
pleted in Marion County in 1956 were
Trenton wells in the Patoka pool. The
Trenton was a new pay at Patoka, but is an
important pay in the Centralia and Salem
Consolidated pools, so its discovery at Pa-
toka may prove to be one of the most im-
portant developments of 1956.
* Estimated in part and subject to revision. Includes 2,960,
000 barrels of oil produced before 1937.
No new pool was discovered in Marion
County in 1956. Twelve of the 30 produc-
ing wells were in the Patoka pool and most
of the others scattered throughout the
county with only two or three in any one
pool. The 29 dry holes included 16 dry
holes in pools and 13 wildcats.
Secondary recovery has been very impor-
tant in the Marion County pools. One of
the earliest waterfloods in the basin was
begun in the Patoka pool in 1943. In 1956
waterflooding is credited with 143,000 of
the 231,000 barrels of oil produced from the
Patoka pool. Later, smaller floods were
begun in the Odin, Tonti, and Wamac
pools.
In 1950 the Salem Unit was set up and
flooding of the Salem Consolidated pool
was begun. At that time it was the largest
unitized project in the United States. In
1956, the Salem Consolidated pool pro-
duced 4,906,000 barrels of oil by secondary
recovery operations. Secondary recovery
projects in Marion County produced 5,-
129,000 barrels of oil in 1956. The total
amount so far produced in the county by
secondary recovery is about 22,700,000
barrels.

Monroe County has only one oil or gas
pool, and has had only one producing well
completed in 15 years.
Waterloo, the only pool, was discovered
in 1920; 23 producing wells were drilled
before 1937, and there was another period
of development in 1939 and 1940.
In 1951 the northern part of the pool was
converted into underground gas storage.
Three producing wells at the southern end
of the pool still produce a small amount of
oil.
Montgomery County
Fig. 20, Area 15
Montgomery was one of the counties hav-
ing the biggest increases in drilling in 1956.
The 31 wells drilled in 1956 included one
dry pool test and 30 wildcats. In the past
four years 70 wells have been drilled, all
of them dry. Most of the oil produced in
Montgomery County has come from Penn-
sylvanian pays. Recent development of
Devonian and Silurian production in
Christian and Bond counties encourages
the hope that deep production may also be
1937.

At present Morgan County has two pools,
Prentice and Waverly, both of which were

discovered by gas wells and now contain
non-producing oil and gas wells.
Superficially Morgan County appears to
have a fair record with one-fourth of its
wells completed as producers. However, all
three oil wells were too small to be operated
profitably and have been non-operating
since completion. The gas has been too
limited in quantity to be utilized for any
considerable period, so most of the wells
were capped when completed.
An attempt has been made to use the
Waverly pool for gas storage but without
success to date because of leakage from the
reservoir. Another attempt at some time in
the future is planned.
The Jacksonville Gas pool in Morgan
County was discovered in 1910 and aban-
doned in 1939 after producing an unknown
quantity of gas.
Although Morgan County has two oil
and gas pools, and completed a new gas well
in 1956, it has no commercial production
and is located in a part of the state where
there is only a slight possibility of finding
a good pool.

Moultrie County had more wells drilled
last year than in any previous year; the
22 wells completed in 1956 are almost a
third of the total number of wells drilled
in the past 20 years. One of the 1956 com-
pletions was a dry hole in the Gays pool;
the other 21 were unsuccessful wildcats.
Undoubtedly much of the increased in-
terest shown in Moultrie County in 1956
was due to the successful development of
the Cooks Mills — Bourbon area only a few
miles to the east. However, results of ex-
ploratory drilling were as unsatisfactory in
northern Douglas County as in Moultrie
County, so it is unlikely that the 1956 rate
of wildcat drilling will continue into 1957.
The only oil pool in Moultrie County is
Gays in the extreme southeastern part, only
a few miles west of Mattoon. Production
for 1956 was 6,000 barrels, making a total
production of 17,000 barrels for the county.

Perry County has oil production on all
sides and should have good possibilities,
but results so far have been disappointing.
In 1956, 24 wells were drilled; one dis-
covered a new pool, Tamaroa West, two
were dry holes in pools, and 21 were un-
successful wildcats.

As a result of the discovery of the Fish-
hook pool in 1955, Pike was one of the
counties which showed major increases in
drilling in 1956. Results of drilling showed
a percentage of successful completions
much higher than that for the state as a
whole.
The 48 completions in 1956 included
38 gas wells and two dry holes in the Fish-
hook pool and eight unsuccessful wildcats.
The gas wells were capped on completion.
At the end of the year it seemed probable
that an attempt would eventually be made
to use the pool for underground storage.
Pike County has had no oil production.
An earlier gas pool, the Pittsfield or Pike
County Gas pool, discovered in 1886, mar-
keted some gas, but no production data
are available.
pools produce from Silurian pays.
A little oil and gas were produced in the
Sparta area between 1888 and 1900, and
again in 1949. Production data are lack-
ing, but quantities of oil and gas were
negligible, and the oil is not included in the
table for Randolph County.
Richland County
Fig. 13, Area 8
No new pool or important new pay was
discovered in Richland County in 1956.
Most of the 40 producing wells were in the
Clay City Consolidated pool. The 37 dry
holes included 23 in pools and 14 wildcats.
Six Richland County oil pools have sec-
ondary recovery projects, but all are small
or too new to have produced much oil.

All of the oil production shown in the
table is from the Dupo pool which was dis-
covered in 1928. By 1937 a total of 237
producing wells had been drilled, only 45
of which were still in operation. The en-
tire pool was shut down late in 1954, but
30 wells were put back into operation in
1955.
The Freeburg South pool, consisting of
one small well, was discovered in 1955.
Three wells were drilled in 1956, two wild-
cats and one pool dry hole which was later
worked over into a small gas well. Both oil
and gas production in Freeburg South must
be considered non-commercial.

Saline County had its second biggest year
for both drilling and production in 1956.
The Eldorado Consolidated pool was al-
most completely drilled up in 1955; the
1956 drilling was concentrated in an area

west and northwest of Eldorado Consoli-
dated in the Harco, Harco East, and Dale
Consolidated pools. These three pools had
93 of the 107 producing wells completed
in 1956. Almost all of the new wells pro-
duced from the Aux Vases sandstone, alone
or in combination.
The decrease in production from
4,099,000 barrels in 1955 to 2,390,000 bar-
rels in 1956 was a result of the much
greater drop in production in the Eldor-
ado Consolidated pool where the decrease
was from 3,521,000 barrels (1955) to
965,000 barrels (1956). Part of the decrease
in production in the Eldorado Consoli-
dated pool was compensated for by major
increases in the three pools where drilling
was heaviest. Harco showed the biggest
gain, from 6,000 to 547,000 barrels; Dale
Consolidated increased from 110,000 to
406,000 barrels, and Harco East from 9,000
to 133,000 barrels.
Two new pools, Pankeyville and Pankey-
ville East, were discovered in Saline County
in 1956. At the end of the year Pankeyville
consisted of two Cypress wells which had
produced 5,000 barrels of oil and Pankey-
ville East had only 1 well and had not mar-
keted any pipeline oil.
The 113 dry holes drilled in 1956 in-
cluded 58 pool dry holes and 55 unsuc-
cessful wildcats. In drilling, Saline County
ranked fifth in the state for 1956, dropping
back from the second place position it held
in 1955.
Sangamon County
Fig. 18, Area 13
Sangamon County has had a poor record
so far as an oil producing county. Less than
10 percent of the wells drilled have been
completed as oil wells and of the 10 "oil
wells" at least three were economically un-
successful.
Roby, the oldest pool in the county, was
discovered in 1949, but no oil was reported
as marketed until 1956, when 3,000 barrels
of oil was produced.
The biggest pool is Edinburg West, most
of which is in Christian County. The four

pool wells which are in Sangamon County
produced 29,000 barrels in 1956 to make
a total production of 60,000 barrels.
The New City pool (three wells) pro-
duced 8,000 barrels in 1956 for a total of
35,000 barrels.
Glenarm, the only other pool, consists
of one well which has produced less than
1,000 barrels of oil.
The 22 wells drilled in 1956 included
three pool dry holes and 19 wildcats. All
production in the county is in the south-
eastern part within 10 miles of Christian
County, and it is doubtful that produc-
tion with commercial value will be found
much farther to the north or west.
Shelby County
Fig. 19, Area 14
Shelby County is in an area where pos-
sibilities for oil or gas production should be
moderately good, but actual results, as
shown in the table, have been poor. Only
about 10 percent of the wells drilled have
been completed as producing wells, and
not all of them produced enough oil to
pay drilling costs. The 18 wells drilled in
1956 include one producing well in the

Stewardson pool and 17 unsuccessful wild-

Shelby County has four pools. The best
of them, Lakewood, produced 9,000 bar-
rels last year for a total of 234,000 barrels
of oil. Stewardson also produced 9,000 bar-
rels in 1956, making its total 161,000 bar-
rels. Clarksburg has produced 21,000 bar-
rels including 2,000 last year, and Shelby-
ville Consolidated, 28,000 barrels including
1,000 in 1956.
Wabash County
Fig. 8, Area 3
Wabash is the only county in the extreme
southeastern part of the state which had
an increase in drilling in 1956. In 1955 it
was one of the few counties which showed
decreased drilling. It has probably had
more of its area drilled than any other
county in Illinois.
No new pool or pay was discovered in
1956. Fifteen of the 89 new producing wells
were in the Gards Point pool, and most of
the others in the New Harmony Consoli-
dated pool. The 87 dry holes included 77
in pools and 10 wildcats.
Secondary recovery operations are a ma-
jor factor in maintaining the level of pro-
duction. In 1956, 1,155,000 barrels of oil,
more than one-third of the year's produc-
tion, was the result of secondary recovery
in the Allendale, Browns East, Friendsville
North, Keensburg South, Lancaster South,
Mt. Carmel and New Harmony Consoli-
dated pools. About 4,300,000 barrels of sec-
ondary recovery oil have been produced.
Washington County
Fig. 14, Area 9
More wells were drilled in Washington
County in 1956 than in any previous year.
However, a comparison of 1956 with 1939,
previously the highest drilling year, shows
that in 1939 almost three-quarters of all
wells drilled were successful, whereas in
1956 only a third were successful. Of the
135 wells drilled in 1956, 45 were com-
pleted as oil wells, two as capped gas wells,
41 as pool dry holes, and 47 as unsuccessful

No new pool was discovered in Washing-
ton County in 1956, but the New Memphis
South pool was extended from Clinton
County into Washington County.
One new deep pay was discovered; in
the Irvington pool the first Trenton wells

ere completed. All five of them were
.mall, but Irvington is close to the Cen-
ralia and Salem Consolidated pools, both
)f which have good Trenton production.
Most of the new producers drilled dur-
ng the year were in Irvington (11 oil wells)
)r Dubois Consolidated (26 oil wells and
:wo gas wells).
Production was high in 1956, but not as
ugh as in 1940, 1941, and 1942 when the
[rvington and Cordes pools were at their
production peaks. Secondary recovery, be-
^un in the Cordes pool in 1950, has been
^ery important in maintaining the level
)f production in Washington County. Pro-
luction in the Cordes pool increased from
191,000 barrels in 1950 to 689,000 in 1951.
V corresponding increase for the county is
.hown in the table. In 1956, secondary re-
covery is credited with 155,000 barrels of
>il, about 13 percent of the county's pro-
luction of 1,159,000 barrels for the year.
\bout 2,139,000 barrels of oil has been pro-
luced by waterflooding.
Wayne County
Fig. 12, Area 7
In 1955 Wayne County showed a major
lecrease in number of wells completed, a
contrast to the over-all increase in the
state. In 1956 there was a small decrease
which was about the same as that for the
entire state.
One new pool, Orchardville North, was
discovered in Wayne County, the only 1956
discovery in the deep, densely drilled part
of the basin. Only one well had been com-
pleted at the end of the year; its produc-
tion was about 2,000 barrels.
Wayne County had a better drilling
record in 1956 than most counties. Of the
236 completions, 137 were producers and
only 99 were dry holes. The dry holes in-
cluded 69 in pools and 30 wildcats.
Wayne is another of the deep basin coun-
ties that is rapidly becoming drilled up.
However, only a dozen or so wells have
tested the deepest Mississippian and pre-
Mississippian strata, so there is still a pos-
sibility of developing deeper production.
Five pools in Wayne County — Aden
Consolidated, Barnhill, Clay City Consoli-
dated, Goldengate Consolidated, and Keen-
ville — have secondary recovery projects in
operation. Waterfloods in those five pools
produced 1,185,000 of the 7,614,000 barrels
of oil produced in Wayne County in 1956,

White County is currently producing
more oil than any other county in Illinois
except Fayette. However, two other coun-
ties, Marion and Lawrence, have produced
so much more oil than White County, it
is doubtful that White will be able to sur-
pass them.
White County had the biggest decrease
in drilling in 1956. Few counties have had
more wells drilled, and most of the county
has been tested through the Ste. Genevieve
formation. Very few wells have gone
deeper.
No new pool or important new pay was
discovered during the year. Of the 148
producing wells completed in 1956, 42 were
in Phillipstown Consolidated, 27 in Herald
Consolidated, 25 in Roland Consolidated,
and the remainder distributed in small
numbers among other pools. The 114 dry
holes include 88 dry holes in pools and 26
wildcats.
In 1956, 2,206,000 barrels of oil, almost
one-fourth of the year's production, were
produced by secondary recovery projects in
eight pools: Albion Consolidated, Center-
ville East, Concord Consolidated, Herald
Consolidated, New Haven Consolidated,
New Harmony Consolidated, Phillipstown
Consolidated, and Roland Consolidated.
Total oil recovered by waterflooding
amounts to 9,470,000 barrels.

With a total of 81 wells drilled in the
past 20 years Williamson County has had
no commercial well completed. In 1950 a
dry hole was worked over and less than
500 barrels of oil obtained from it. Develop-
ments in Saline and Franklin counties dur-
ing 1955 and 1956 extended production in
those two counties almost to Williamson
County. It is reasonable to assume that
some production will be discovered in
northern and eastern Williamson County,
although it may be limited in quantity and
area.

Wildcat wells were drilled in 1956 in 18
counties which have had no oil or gas pro-
duction.
Champaign County had six wildcats,
more than in any previous year. This in-
crease in drilling probably resulted from
the discovery in 1956 of three new oil pools
in Douglas County, the adjoining county
on the south.
Schuyler County had five wildcats, which
is an unusually high number for that
county also.
Each of five counties had two wildcats:
Brown, Logan, Massac, Piatt, and Pope.
Each of the remaining 1 1 counties had
one wildcat: Alexander, Cass, Fulton,
Greene, Jersey, Johnson, Kendall, Menard,
Peoria, Pulaski, and Tazewell.
Geographic distribution of these "wild-
cat" counties is less widespread than dur-
ing most recent years. Only one county,
Kendall, is in the northern quarter of the
state, and only one other, Peoria, is in the
northern third.
Twelve of the 18 counties are adjacent
to counties in which oil or gas has been
found. Thirteen of these counties lie north
and northwest of the basin productive
area, but 12 are wholly or largely within an
area considered to have moderate possi-
bilities for oil or gas production (see fig. 4).
Kendall on the north and Alexander,
Johnson, Massac, Pope, and Pulaski are
shown as having slight possibilities.

PART II
WATERFLOOD OPERATIONS
ABSTRACT
During 1956, waterflooding produced approximately 31,300,000 barrels of oil in Illi-
nois. There were 333 waterfloods reported in operation, and these projects recovered
29,600,000 barrels of oil. An additional 1,700,000 barrels are estimated to have been pro-
duced by "dump" flooding. At the end of 1956, the cumulative waterflood recovery was
133,200,000 barrels. Tables of statistics are included.
INTRODUCTION
This report is the result of a joint effort
by the Illinois State Geological Survey and
the Illinois Secondary Recovery and Pres-
sure Maintenance Study Committee of the
Interstate Oil Compact Commission. The
following persons were appointed to the
Study Committee by Governor William G.
Stratton to assist in the compilation of data
on the waterflood and pressure mainten-
ance projects that were in operation in Illi-
nois during 1956.

SUMMARY OF RESULTS
Continuing the trend of the past few
years, oil production in Illinois during
1956 was slightly larger than the produc-
tion of immediately preceding years. As
can be seen in figure 25, this rise in pro-
duction can be attributed almost entirely
to the large increase in oil recovered by
means of waterflooding. This method
of secondary recovery produced approx-
imately 31,300,000 barrels of oil during
1956, or 38 percent of the state's total re-
covery of 82,314,000 barrels. Of this water-
flood oil, 29,600,000 barrels is reported in
table 14, and an additional 1,700,000 bar-
rels is estimated to have been recovered
by "dump" flooding. The 1956 waterllood
recovery is 18 percent higher than the 1955
recovery of approximately 26,560,000 bar-
rels.
Figure 25 shows the effect of waterflood
(including "dump" flood) operations on
the state's annual oil production since 1936.
The cumulative waterflood recovery at the
end of 1956 was approximately 133,200,000
barrels, which includes 21,500,000 barrels
of "dump" flood oil.
Table 14 presents a summary of the in-
formation collected on waterflood projects
in operation during 1956. The data are ar-
ranged alphabetically by fields and include
333 projects. Excluding the "dump" floods,
there were approximately 350 waterfloods
in operation during 1956. Table 14 pro-
vides data on 95 percent of these projects,
although in terms of cumulative figures,
this summary approaches 100 percent cover-
age.
Based on the reported data in table 14,
a total of 271,270,000 barrels of water was
injected during 1956 in recovering
29,600,000 barrels of waterflood oil, or a
ratio of 9.2 barrels of water for each barrel
of oil. A cumulative total of 1,014,900,000
barrels of water had been injected by the
end of 1956 in recovering 111,540,000 bar-
rels of oil, or an over-all input water-oil
ratio of 9.1.
Figure 26 shows the reported develop-
ment of waterflood projects in Illinois by
years since 1942. The rapid increase in the
number of projects since 1919 is evident.
As a result, the number of projects has
increased by a factor of ten in the past
seven years from 33 projects at the end of
1949 to 333 projects at the end of 1956.
As shown in table 14, these 333 projects had
developed 92,350 acres of waterflooding, or
17 percent of the state's total oil-productive
acreage. There were 5,307 injection wells
and 7,687 producing wells reported operat-
ing in these projects in 1956.
Table 15 presents data on the waterflood
projects that have been reported aban-
doned by the end of 1956. Several projects
previously reported as temporarily aban-
doned were added to this table along with
three projects abandoned during 1956,
bringing the total projects reported aban-
doned to 22.
Table 16 includes data on the eight pres-
sure maintenance operations that used
water injection during 1956. The oil-pro-
duction statistics in table 16 include both
primary recovery and any additional oil
obtained by pressure maintenance oper-
ations.
Each project listed in tables 14, 15, and
16 has been numbered, and corresponding
numbers on figures 27, 28, and 29 show
the locations of the waterflood and pres-
sure maintenance operations. Figure 27
shows all reported projects, while figures 28
and 29 show details of portions of the old
oil fields and the Wabash Valley fields,
respectively.
For a generalized geologic column, see
figure 3, which indicates the stratigraphic
sequence of oil-producing formations in the
Illinois basin. Given below is a list of the
oil-producing formations with the number
of reported waterfloods, as taken from table
14. An index map of counties, townships,
and ranges in Illinois is shown in figure 5.
