System and method for moment tensor migration imaging

摘要

A method for estimating moment tensor components of a source can use a waveform based method that performs a stack function on projected data from each sensor. The method can produce a cumulative result for each moment tensor component, for each propagation phase at each image point and origin time. A system for use in imaging a subterranean region of interest can include instructions which operate on recorded actual seismic data output from seismic receivers having known positions, and at least one processor, whereby the instructions cause the processor to project a selected data sample from the seismic data onto a moment tensor component.

1. A method of imaging a subterranean region, the method comprising:
recording actual seismic data output from a plurality of seismic receivers of known positions; inputting the seismic data to a processing system; and the processing system executing instructions which project a data sample from the seismic data onto at least one moment tensor component.
