This report summarizes December 1979, progress of the government-sponsored projects directed toward increasing gas production from the low-permeability gas sands of the western United States. The USGS continued work toward resource assessment in the four primary areas. Coring of the Rainbow Resources No. 1-3 Federal well, Sweetwater County, Wyoming, was initiated. Research continued at the National laboratories and Energy Technology Centers on improvement of enhanced gas recovery. Work on improved coring systems, logging studies, in situ permeability and rock/fluid interaction continued for Bartlesville Energy Technology Center. Los Alamos Scientific Laboratory continued in the nuclear magnetic resonance studies, and at Sandia Laboratories nuclear magnetic resonance testing continued on eleven cores. The Texstream diaphragm regulator has been installed at the Colorado Interstate Gas Company cyclic injection site. Twenty-three coreholes have been completed at the Sandia Hole No. 6 formation interface fracture experiment at the Nevada Test Site.
