Technical Paper: Anisotropic PP and PSv Prestack Depth Migration of 4C Seismic Data: Pamberi, Trinidad

In this paper, we present precisely that next phase in the 4C processing, advancing the P- and PSv-wave data through anisotropic prestack depth migration, using cell-based tomography with a top-down layered approach. The Pamberi-1 well was used to constrain the anisotropy in the shallow section, with the deeper spatial trend away from the proximity of the well determined from the anisotropy derived previously in the time processing.
