The Western Gas Sands Project Implementation Plan, Project Plan Document FY 78, and the Quarterly Basin Activities report are in various stages of preparation. Resource assessment by the USGS is continuing. Some base maps are completed and others are being prepared. Core from the Book Cliffs area has been made available to USGS for study and core sampling from the northern Green River Basin is continuing with fourteen additional samples submitted for paleoanalysis. Research and Development by Energy Research Centers and National Laboratories funded by the Department of Energy (DOE) is continuing. These activities are directed toward the development of new tools and instrumentation systems, rock mechanics, mathematical modeling and data analysis. The field tests and demonstrations being carried out in the Uinta and Piceance Basins are: Gas Producing Enterprises (GPE)--Natural Buttes No. 14, 18, 19, 20, 21, and 22; Mobil Research and Development--F-31-13G; and Rio Blanco Natural Gas--498-4-1. Colorado Interstate Gas (CIG) is preparing to commence field activities in January 1978 in the Wattenberg Field of northeastern Colorado.
