This report covers the second year of the Phase II program at Logan Wash, Colorado, where the technical feasibility demonstration of OOSI's vertical modified in situ oil shale retorting process (MIS) is being undertaken in concert with the development of the commercial C-b Tract in Rio Blanco County, Colorado. Among activities at OOSI's Logan Wash site during this period were: mining of access drifts, mining to create the retort voids, continued construction of surface buildings, ignition of Mini-Retorts 3 and 4 to obtain information and data needed for the successful ignition of Retorts 7 and 8, rubbling and cleanup of Retorts 7, 8, and 8X, and development of the R7 and 8 sampling program. Also, installation of instrumentation for processing and construction of the bulkheads were begun for R7 and 8, which are two side-by-side commercial-size retorts in a three-level design. Retort 8X, a partial retort, was rubbled January 24, 1981, Retort 7 on February 21, and Retort 8 on April 4. Mini-Retort 4, a three-level retort funded under the OOSI Rock Fragmentation Program, was rubbled on June 13, 1980. R7 and 8 ignition and simultaneous processing will commence in the fall of 1981. OOSI elected to operate MR3 and MR4 beyond ignition. The data collected from the operation of these retorts will be published with the Retorts 7 and 8 processing data. Appendix A of this report contains a list of Phase II Progress Reports available through the Department of Energy, Technical Information Center.
