The approach to development by Rio Blanco Oil Shale Co. has followed an ambivalent pattern, centering first on a surface mining plan and more recently on its own version of MIS (modified in situ) recovery of shale oil. Development crews ignited the first experimental MIS retort, a small, 30 x 30 x 166-ft-high, rubbled volume, in mid-Oct. 1980. Fracturing of oil shale for a second retort (R1, measuring 60 x 60 x 400 ft high) took place to start construction of 4400 short tons/day Lurgi-Ruhrgas (L-R) oil shale retorting module later this year. The L-R retort is expected to be capable of recovering approximately 2000 bpd of shale oil from oil from the feed. A potential open-pit mining area is mapped, schematics show open-pit development and an idealized MIS retort, and diagrams illustrate idealized product flow for MIS retorting and a simplified flow diagram for the L-R retorting system.
