Abstract

3D-3C data was acquired in Sayan-Tadkeshwar area of Cambay basin to bring out sand geometry and pinch out prospects within Ankleshwar formation. Converted wave data of this volume was processed using two different approaches of shear wave statics refinement. Final processed PSTM stack with alternate approach of shear statics refinement, consisting of trim statics in receiver line domain after structural flattening, has brought out an improved image of subsurface.
