Determining directional propagation attributes of a seismic event

摘要

A method comprising: obtaining seismic data acquired in a common receiver gather; and processing the seismic data to determine a value indicative of a three-dimensional directional propagation attribute of a seismic event based on the first seismic data, comprising: determining a two-dimensional angle of incidence of the seismic event; determining an azimuth of the seismic event; determining a three-dimensional incidence angle based at least in part on the two-dimensional incidence angle and the azimuth; and identifying a geologic structure based at least in part on the determined three dimensional angle of incidence. 5479082_1 (GHMatters) P85152.AU.1 SARAHVV 25/08/2014 5858 42 5 8 5 0 5 63 04 58 58 58 10 X 24 x5
