Abstract

In the Southeast Asia offshore exploration, shallow reefs and channels, widely spread volcanic rocks and basement fracture system are some of the major challenges in seismic imaging. Geo-mechanical modeling, reflectivity inversion and TTI/HTI modeling in basement are introduced in this area. Together with the conventional reflection tomography, they generate high resolution velocity model for PSDM thus provide much needed imaging uplift.
