Abstract

Complex geological structures often are three dimensional. Reservoir mapping with existing 2D data is extremely difficult job even after reprocessing the same data in these areas. Mapping these reservoirs has been a major challenge. The area is revisited for 3D data acquisition with 3D survey geometry. The pre stack imaging in time of the 3D volume have brought out a new play concept and enabled defining the reservoir limits with more confidence because 3-D migration eliminated sideswipes and ambiguities in bringing out blind structures.
