Abstract
A moment tensor is determined using an inversion algorithm for each of a plurality of microseismic events passively detected by receivers. Each of the moment tensors includes two nodal planes. A subset of the microseismic events is grouped into a family of microseismic events. If the microseismic events in the family have a common nodal plane, the common plane is a solution fault plane for the family of microseismic events. Information related to the fault plane is used to optimize fracking operation.
