An imaging case study of ragay SC-43, Philippines: From 2D to 3D PSDM Processing

Abstract

Ragay SC-43 Block was located off the southern tip of Bondoc Peninsula, between the Ragay Gulf and the Sibuyan Sea. Huge carbonate reef was developed and complex faulting system dominated in the shallow sediment in this area. This resulted in a very complex subsurface geology with strong lateral velocity contrast, which made high resolution PSDM processing essential for the successful structure imaging in this area. With dense model representation and optimized inversion regularization, high resolution tomography update can provide detailed velocity modeling. Together with high fidelity controlled beam migration technology, it provided a solution for structural imaging in such a complex area.
