Reservoir engineering, transient pressure well testing, and petrophysical analyses of western gas sands. Annual report, July 1978-August 1979
Improvement in gas deliverability by massive hydraulic fracturing of low permeability Western Gas Sands has been generally disappointing. This investigation uses petrophysical studies, transient pressure analysis of well performance, and parametric study of various fracture properties to aid in the understanding of the results of several DOE cost-shared MHF treatments. Both the transient pressure analysis and the parametric study utilize numerical simulation techniques. A generalized approach to pressure buildup analyses of tests with short flow periods is developed. The parametric analyses are focused on those variables of MHF treatments over which the operator and engineer have some control. Improvements in pressure measurement techniques are suggested as well as reasons why MHF treatments have had limited success.
