Natural gas productivity of E. Devonian shale wells depends on the density and extent of natural fractures within the formation, the organic content of the shale matrix, and the effective communication of the well bore with the natural fracture system. Stimulation techniques are normally required to develop this communication. A strategy for testing stimulation techniques currently is being developed. The strategy for a geologic region involves the selection of the best stimulation technique for specific geologic conditions. This selection is based on the thickness of the organic rich shale units within the formation (recognized as the source of gas) and the degree of fracture density (recognized as the reservoir) as controlled by various geologic elements. Analysis of fluid data shows that for regions of low fracture density, hydraulic fracturing is a slight improvement over borehole explosive stimulation treatments. Results from hydraulic fracturing may be further enhanced whenever retention time of the fracturing fluid in the formation is reduced. (24 refs.)
