Natural Fracture Control of Hydraulic Stimulations in the Carthage Cotton Valley Gas Field: Abstract

James Rutledge1

Abstract

We have improved the location precision, determined focal mechanism and computed the moment release of microearthquakes Previous HitinducedNext Hit during a series of hydraulic fracture completions within the Cotton Valley formation of East Texas. Conventional gel-proppant treatments and treatments using treated water and very low proppant concentrations (waterfracs) were monitored. Waterfracs have been shown to be just as effective as the conventional gel-proppant treatments in Cotton Valley reservoirs, but at greatly reduced cost. Comparison of the Previous HitseismicityNext Hit Previous HitinducedNext Hit by the two treatment types show similar distributions of event locations, focal mechanisms and moment release for common depth intervals. We interpret the Previous HitinducedNext Hit Previous HitseismicityTop to be primarily controlled by the natural fracture geometry and independent of treatment design.
