Moment Tensors of Events Induced in Cotton Valley Gas Field from Waveform Inversion

P227 MOMENT TENSORS OF EVENTS INDUCED IN COTTON VALLEY GAS FIELD FROM WAVEFORM INVERSION. Abstract 1 Induced microseismicity resulting from hydraulic fracturing is routinely monitored to provide essential information about a three-dimensional (3-D) geometrical shape of fracture on the scale of 10s to 1000s of meters. However a better understanding of how the microseismic events are related to the fracture growth may provide crucial information about the fracture itself and reservoir properties which can be used to increase reservoir production. The fundamental question remaining is whether the observed microseismic events are caused directly by propagation of the fracture itself (fracturing
