Those parameters for which core samples are currently being analyzed include: (1) shale oil (2) sodium (3) alumina. content t For the determination of shale oil content, cores are sampled on one-foot intervals and these samples are subjected to laboratory analysis for kerogen content. Each sample is retorted through a specified time curve to yield data on oil content in gallons per ton, water content in gallons per ton, and residue weight in pounds per ton. In addition, gas-plus - loss is calculated for each sample. Analysis for sodium is made from ten-foot composite samples and for alumina on core samples taken from one-foot intervals. Sodium content is determined by leaching one gram of raw shale in water and measuring the dissolved sodium content by atomic absorption. Alumina is determined by leaching one gram of spent shale with 50 milligrams of 20-gram-per- liter sodium hydroxide solution and measuring the soluble alumina by atomic absorption. Alumina in spent shale is then corrected back to a raw shale basis using the Fisher assay weight loss. The laboratory data sheets for those wells on v/hich assays are complete are included in this section of the report. This information, however, is CONFIDENTIAL and is so marked.

Required laboratory analyses are in progress, and no laboratory analytical reports have yet been received by the Lessee. Therefore, these data will be accumulated for the second Quarterly Report.

Currently, all geotechnical data collection and reduction is being performed by a mining consulting firm, Colder Associates, Inc. Data obtained by them or for them are analyzed and correlated for presentation in monthly progress reports. As of November 30, 1974, monthly progress reports had been received on only two holes, AT- la and SG-10. Reports on other holes were awaiting receipt of assay information. Since holes AT-la and SG-10 were the first holes tested, much difficulty was encountered in both obtaining the necessary equipment and actually conducting the tests. Neither shear tests nor triaxial compression tests were run due to the unavailability of equipment. A standard triaxial chamber is being fabricated to accommodate our 3^ inch diameter core, and selected core samples are being saved from currently drilling holes to be triaxially tested when the chamber is available. The following report from the consulting firm, Golder Associates, Inc., presents the rock mechanics data in detail.

The plot is based on a combination of a Baroid Gas Detector strip chart and a geolograph strip chart, which are both time-based plots. The baroid Gas Detector strip chart is a plot of hydrocarbon concentration in the well discharge line versus time. The geolograph strip chart is a plot of drilling depth by feet, each foot indicated by a "kick" on the chart versus time. Since a large amount of drilling time is spent "tripping" (setting pipe up and down the core hole), water testing, and lost time, large quantities of strip chart paper is generated from both instruments which is not meaningful. Therefore, we have plotted the gas concen- tration versus depth, and that plot, is submitted with this report as the most meaningful plot. The original Baroid Gas Concentration Plot and geolograph plots are available fro*m our field geologist's files. • • II P. -49 3 SG--/ :'': ': m Ti~rp -' : M i i i j \"; •. - • - ; , I i : fl i "-v.:-o-.v-.„, i • • ■ • \ . i -•• /: i '-. ! i I i-j-H / : ; i~i~rn~ ' .
