The progress during September of government-sponsored projects, directed towards increasing gas production from low permeability gas sands of the Western United States, is summarized. Coring operations began at the Mountain Fuel Supply Mesa Unit No. 1 well, Pinedale Field, Sublette County, Wyoming. Negotiations are still being conducted with Superior Oil Company to acquire a 640-acre lease in Garfield County, Colorado, for the Piceance Basin multi-well experiment. During September, LLL continued exploration of the use of polycarbonate to study fluid flow in cracks. An important milestone was passed this month at LASL with the measurement of transverse relaxation time on WGSP core in simulated downhole geometry. A strain-relaxation technique to determine maximum and minimum horizontal stresses from oriented core has been demonstrated on NTS core by Sandia National Laboratories.
