Paper Summary

Increased industry exploration interest in the Tarakan Basin, offshore East Kalimantan, Indonesia, has stimulated a need for 3D seismic data that incorporates recent advances in imaging and velocity model building. The area forms part of an extensive Tertiary-age play fairway. New data is needed to assist in improving the understanding of the complex structural and stratigraphic setting of this important oil and gas province, particularly in prospect delineation and well planning. A reliable seismic image is crucial to understanding the complex fault system that dominates the regional structural framework in this area. In this paper we present a case history of some recent processing that resulted in high quality pre-stack depth migration (PSDM) seismic images from anisotropic VTI PSDM and a geologically-correlated velocity model.
