The ignition of Geokinetics first full-sized prototype retort (Retort 24) was completed on December 1, 1980. Recovery of oil from Retort No. 24 began about midway through December, and 531 barrels of oil had been recovered by the end of the quarter. A cold oil effect resulted in the accumulation of oil within the retort. Five thousand one ninety one barrels of oil were shipped to WESRECO, Salt Lake City, Utah during the quarter, and the shale oil was blended into No. 5 fuel oil, which was sold to industrial users. The Retort No. 25 post-blast core drilling program was completed in October. A total of seven core holes were drilled. Evaluation of the core samples was underway. Preliminary analysis indicated good breakage in the lower portion of Retort No. 25. A new technique for sealing retort surface fractures was designed and implemented on Retort No. 25. A layer of bentonite with gas and steam retention properties was applied to the retort surface and covered with a layer of topsoil.
