This project was a cooperative program with Yates Petroleum Corp. of Artesia, NM. The purpose of the project was to improve gas production from an existing well in the low-permeability Permian Pennsylvanian carbonate reservoir. After reviewing engineering and production data from 23 wells in the 50 sq-mile area investigated, the Griffin J.J. No. 1 was selected by Yates as being representative of most of the wells producing from this reservoir. Prior to the large-scale stimulation treatment, pressure buildup tests were conducted and analyzed. From this testing, the formation flow capacity was estimated to be 2.6 md-ft, the permeability was calculated to be 0.09 md, and a negative skin factor of about 4.0 was indicated. The very low skin effect suggested that a successful stimulation treatment must penetrate far away from the wellbore and intersect pockets of gas that were not flowing through the low-permeability flow paths. Proposed treatment programs were obtained from three different service companies. The program employed was a massive hydraulic fracture treatment that included 224,000 lbs. of 20 to 40 mesh sand, 140,000 gallons of gelled 2% KCL water, and 70,000 gallons of liquid CO/sub 2/. On September 22, 1981, this treatment was pumped into the Griffin well at an average treating pressure of 9000 psi. After some early production problems, the gas production two months after the treatment was approximately twice the pre-stimulation level. Four months after the stimulation, gas production was almost three times the rate prior to the treatment; to date, this increased production has been sustained for six months. Based on the observed increase in gas production, the massive fracture treatment was economically successful.
