Book Description
The Geokinetics in situ shale oil project is a cooperative venture between Geokinetics and the US Department of Energy. The objective is to develop a true in situ process for recovering shale oil using a fire front moving in a horizontal direction. The project is being conducted at a field site, Kamp Kerogen, located 70 miles south of Vernal, Utah. This fifth annual report covers work completed during the calendar year 1981. During 1981, one full sized retort (Retort No. 26) was blasted and the following three retorts were processed: (1) Retort No. 24 operations were continued until July 23; (2) Retort No. 23 was ignited and processed during the calendar year; (3) Retort No. 25 was ignited and burned for 77 days during 1981.

Book Description
The Retort No. 25 burn was terminated on June 15, 1982. Total oil production for the second quarter was 6506 barrels during a 76 day production period. Final oil production for Retort No. 25 was 20,956 barrels. Final oil recovery was calculated to be 59% of the total in-place oil. Fugitive emissions, stack and process gas data indicated that all Retort No. 25 pollutants, except NO/sub x/, were below the allowable PSD limits. The Retort No. 25 process water characterization study was completed in April to determine the changes in retort produced water as the retort burn progressed. Results of the study are pending the completion of laboratory analysis. Retort No. 26 was prepared for ignition during the second quarter. Process manifolding and instrumentation were being completed so that ignition might occur shortly after the termination of the Retort No. 25 burn. Post blast core drilling and analysis was completed on Retort No. 27 during early April. The core samples indicated improved fracturing over previous retorts, especially near the bottom. Increasing the size of Retort No. 27 from one acre to two acres showed an increase in blast efficiency based on the criteria of fragmentation, quantity of explosives used per volume of void induced and percent void when compared with Retort No. 24. In June initial site preparation began on Retort No. 28 for blast hole drilling which will start in July.

Book Description
At the end of March 1982, Retort No. 25 was in its 167th day of burning with a total oil production of 16,599 barrels, an average of 99 barrels per day for this five month burn period. Total oil production for the first quarter was 9187 barrels, an average of 3062 barrels per month or 102 barrels per day. Various environmental studies were carried out on Retort No. 25 during this burn period, as defined in the Environment Research Plan. Stack gas analyses show that the retort operated within the PSD established emission levels. Lab and field experiments continued on a wet scrubber to remove H/sub 2/S and NH/sub 3/ from the process gas. Process and instrumentation wells were drilled on Retort No. 26. All process holes were completed in February and all instrumentation holes were finished in March. Installment of process manifolding, surface piping and thermocouples is continuing. The Retort No. 27 site was prepared for blasting during January and February with detonation of the retort accomplished on February 25. Retort No. 27, the first 2 acre retort, used 283,000 pounds of Ireco explosive loaded into 354 blast holes. Important data concerning the effect of retort size increase, early overburden motion and the effects of blast design modifications upon shale fracturing characteristics were obtained from this blast. Preliminary indications show that the blast was a success and post blast analysis is presently in progress to evaluate the characteristics of the blast. During the quarter, the second and third suite of samples for the Retort No. 25 fugitive emissions study were gathered. From this study, it was concluded that more sampling will be required before fugitive emission rates can be properly characterized.
