METHODS AND SYSTEMS OF DETERMINING A FAULT PLANE OF A MICROSEISMIC EVENT

摘要

The present disclosure includes a method of passive seismic data processing comprising determining a moment tensor for each of a plurality of microseismic events using an inversion algorithm and raw data detected at a plurality of receivers, each of the moment tensors including two nodal planes and grouping a subset of the plurality of microseismic events into a family of microseismic events. The method also includes determining whether the family of microseismic events include a single plane that is common across each of the nodal planes of the microseismic events for the moment tensors of the family of microseismic events. The method additionally includes selecting a solution fault plane for the family of microseismic events, the solution fault plane being the single plane. The present disclosure may also include associated systems and apparatuses.

1. A method of passive seismic data processing comprising:
determining a moment tensor for each of a plurality of microseismic events using an inversion algorithm on raw data detected at a plurality of receivers, each of the moment tensors including two nodal planes; grouping a subset of the plurality of microseismic events into a family of microseismic events; determining whether the family of microseismic events include a single plane that is common across each of the nodal planes of the microseismic events for the moment tensors of the family of microseismic events; and selecting a solution fault plane for the family of microseismic events, the solution fault plane being the single plane.
