This book was released on 1982 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase II of the Cooperative Agreement between the Department of Energy (DOE) and Occidental Oil Shale, Inc. (OOSI) has the primary objective of simultaneously processing two commercial-size modified in situ (MIS) retorts. Most of the data obtained from this program will appear in the Summary Report to be issued six months after the completion of Phase II. This Final Report summarizes the progress of the project through August 19, 1981, the effective data of the DOE discontinuance of funding. As agreed under Modification 014 to the Agreement, there will be no reports between this Final Report and the Summary Report. Through the Discontinuance, the work covered in Phase II include: mining for, and formation of, Retorts 7, 8, and Room 8X (R7, 8, and 8X); construction of processing facilities; installation of mine stability and processing instrumentation; collection and analysis of a R7 and 8 core; execution of a mini-retort blast and ignition test program; and continuous environmental support.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Occidential Oil Shale, Inc. (OOSI) recently completed the demonstration of mining, rubblization, ignition, and simulataneous processing of two commericalized modified in situ (MIS) retorts at the Logas Wash facility near DeBeque, Colorado. Upon completion of Retort 6 in 1978, Occidential began incorporating all of the knowledge previously acquired in an effort to design two more commercial-sized MIS retorts. Any commercial venture of the future would require the ability to operate simultaneously more than one retort. Thus, Retorts 7 and 8 were developed during 1980 and 1981 through joint funding of the DOE and OOSI in Phase II. Rubblization of the retorts produced an average rubble void of 18.5% in the low grade shale (17 gallons per ton) at the Logan Wash site. After rubblization, bulkheads were constructed, inlet and offgas pipes were installed and connected to surface processing facilities and liquid product handling systems were connected to the retorts. Extensive instrumentation was installed in cooperation with Sandia National Laboratories for monitoring the complete operation of the retorts. After pre-ignition testing, Retort 8 was ignited in December of 1981 and Retort 7 was ignited in January of 1982. The retorts were operated without interruption from ignition until mid- November of 1982 at which time inlet gas injection was terminated and water quenching was begun. Total product yield from the two retorts was approximately 200,000 barrels of oil, or 70% of the Fischer Assay oil-in-place in the rubblized rock in the two retrots. Water quenching studies were conducted over a period of several months, with the objective of determining the rate of heat extraction from the retorts as well as determining the quantity and quality of offgas and water coming out from the quenching process. Data from these studies are also included in this Summary Report. 62 figs., 18 tabs.
