Evaluation of an In-situ Retorting Experiment in Green River Oil Shale.

Carpenter HC; Burwell EL; Sohns HW
J Petrol Technol 1972 Jan; 24:21-26
The purpose of this evaluation was to obtain information on the amount of oil shale that was affected by underground combustion, the amount of oil that was produced, the amount of oil that could be recovered, the areal extent, thickness, and depth of the combustion zone, and the preferential direction of travel of the zone. The combustion experiment was conducted in a section of oil shale 20 ft thick located 68 to 88 ft beneath the surface of the ground. Two core holes were drilled before combustion was started, and 18 additional ones were drilled after the experiment was ended 6 weeks later. Areal extent of the zone investigated was approximately 10,000 sq ft. Approximately 30,200 gal of oil was produced, of which 8,000 gal was recovered aboveground.
