Abstract

Summary

GOM subsalt imaging often suffers from poor illumination due to salt related wave field distortion even with full azimuth acquisition. Subsurface RTM 3D dip-azimuth gathers provide structure oriented imaging by separating seismic data into different dip/azimuth components. Together with staggered acquisition full azimuth data, RTM 3D dip gathers have great potential for revealing poor illumination zones in subsalt through interpretation guided enhancement. The paper also studies the sensitivity to the interpretation errors and discusses potential application of dip gather enhancement to aiding interpretation.
