Chemically Assisted in Situ Recovery of Oil Shale. [Quarterly Report], April 1, 1990--June 30, 1990

The objective of this work is to investigate, in the laboratory, the parameters associated with a chemically assisted in situ recovery procedure, using hydrogen chloride (HCI), carbon dioxide (CO{sub 2}), and steam (H{sub 2}O), to obtain-data useful to develop a process more economic than existing processes and to report all findings. The technical progress of the project is reported. The progress of the project is that experiment preparations are underway. Reactor design, process design, and experiment design have been completed. The laboratory to be used has required extensive clean-up, and is nearly ready. Safety considerations are underway. Finally, an initial literature search has revealed some important aspects that need to be considered.

Mineral Resources of the Willow Creek and Skull Creek Wilderness Study Areas, Moffat County, Colorado

Abstract: The Willow Creek Wilderness Study Area (CO-010-002) and the Skull Creek Wilderness Study Area (C-010-003), which contain 13,368 acres and 13,739 acres, respectively, are in northwest Colorado near the Utah border. There are no identified resources in either of the study areas. The study areas have low resource potential for undiscovered uranium, vanadium, copper, and all other metals; oil and gas; and coal.
