High resolution, high quality 3D seismic images from symmetric sampling in practice

A high resolution 3D case study from offshore Thailand demonstrates that a pursuit of 2D symmetric sampling principles, complemented by high density 3D streamer acquisition, a compact source array, and shallow source and streamer towing, can yield comparable temporal resolution to a 2D site survey. The high spatial continuity of the new 3D data provided the optimal platform for a tailored highresolution processing sequence, yielding an outstanding tie between well data and seismic, and delineating individual stacked sand bodies and complex en echelon fault structures.
