Popis: SUMMARY Ragay SC43 Block is 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 results 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, a more detailed velocity model is derived by high resolution tomography update technology. High resolution velocity model is achieved in shallow sediments as well as between huge reef and surrounding sediments. Together with high fidelity controlled beam migration technology, the carbonate reef reservoir was much better imaged which gives valuable information for the future E&P activities in this area.
