abstract: 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.
