Bellow are imaged data from offshore Africa provided by Chevron Overseas Petroleum Corporation.
a) The result of 2-D post-stack processing (NMO, DMO, and time migration) under the assumption of an isotropic medium.
b) The result of 2-D post-stack processing under the assumption of a transversely isotropic medium.
The improvements include better fault imaging as well as better continuity of horizontal reflections. However, some features are better focussed in the isotropic result, and that could partly be attributed to out-of-plane (the plane that contains the sources and receivers) reflections.
