This edition of the WGSP status report summarizes June 1979 progress of government-sponsored projects directed toward increasing gas production from the low-permeability gas sands of the western United States. Background information is provided in the September 1977, status report, NVO/0655-100. Work by the USGS toward resource assessment in the four primary study areas continued. CK GeoEnergy started a core hole in Grand County, Utah. During June, projects of the National Laboratories and Energy Technology Centers continued. Bartlesville Energy Technology Center continued work on fracture conductivity, rock-fluid interaction, and log evaluation and interpretation techniques. Experimental and theoretical work on hydraulic fracturing mechanics and analysis of well test data continued at Lawrence Livermore Laboratory. The CER Corporation RB-MHF 3 final report has been distributed. Cyclic gas injection began again on CIG's Sprague No. 1 well. The DOE well test facility was transported to Vernal, Utah for minor repairs and storage. The GPE wells, Natural Buttes Units 9, 14 and 18 flowed to sales. The Mitchell Energy Muse-Duke No. 1 well flowed 3,000 MCFD in June. Attempts to kill the Mobil PCU F31-13G well failed. Exploratory coring of the Sandia Hole No. 6 Formation Interface Fracture Experiment resumed in June.
