An extensive microseismic data set was collected during threehydraulic fracture operations in the Cotton Valley gas field ofEast Texas. Two 48-level, 3-component geophone arrays weredeployed. We have mapped the microseismicity of the Stage 2completion interval using data from 9 or fewer geophonestations. Gross fracture dimensions obtained from the 9-stationdata were the same as determined from the full-array data.Seismic velocities and station corrections were estimated via ajoint hypocenter-velocity inversion. Master-event relativemapping applied to the most populous cluster of locatedseismicity improved location precision 10-fold and resolved a150-ft-length, horizontal linear feature with width and depthdimensions of less than 10 ft. The linear cluster lies near theupper boundary of the treatment interval and implies that themajority of mapped seismicity is constrained to about 4% of thetotal injection depth interval. Fine-scale temporal growthpatterns were revealed as well.
