SYSTEM AND METHOD FOR IDENTIFYING SUBSURFACE DISCONTINUITIES FROM SEISMIC DATA

摘要

Embodiments of a system and method for identifying discontinuities in a subsurface volume of interest are disclosed herein. Embodiments utilize analysis of azimuthal variations in trim statics corrections calculated on offset groups of flattened CDP gathers to identify discontinuities.

1. A computer-implemented method for identifying discontinuities in a subsurface volume of interest, the method comprising:
a. receiving, at a computer processor, a full-azimuth seismic dataset, wherein the full-azimuth seismic dataset includes flattened common depth point (CDP) gathers; b. sorting, via the computer processor, the CDP gathers into offset groups; c. calculating, via the computer processor, trim statics corrections for each of the offset groups within a time or depth interval of interest; and d. identifying discontinuities based on a particular azimuth set associated with the trim statics corrections.
