OSTI ID:5324119

Gulf Research and Development Company is implementing a DOE-sponsored Underground Coal Gasification project in Steeply Dipping Coal Beds (UCG/SDB) in order to assess the economic and technical viability of UCG in SDB. In the Fall 1980 drilling program, 2 vertical and 2 slant process wells; 3 hydrologic and 1 exploratory well and 4 HFEM wells were completed. The Spring, 1981 program will consist of drilling the remaining instrumentation wells necessary to track the progress of the underground reactor in real time. These will consist of: 6 additional High Frequency Electromagnetic wells (HFEM) and 3 extensometer wells (X). These wells will be installed vertically with an expected deviation of two degrees or less.
