A Modern Reprocessing Sequence, Santos Vision Brazil
Providing better pre-salt images using advanced processing and imaging techniques.
The Santos Vision reprocessing project is rejuvenating the Santos portfolio with the latest processing and imaging technologies including broadband 3D deghosting and designature, 3D SRME demultiple and anisotropic velocity model building including PGS FWI. The final imaging deliverables include Q-Kirchhoff PSDM, 35 Hz RTM PSDM with PGS TA3GS and PGS WEI (Wave Equation Reflectivity Inversion) and is specifically aimed at optimizing the pre-salt targets.

The Santos Basin has seen oil and gas production since the 1970s, and remains active as new technology and play concepts reveal more potential than was ever originally envisioned. Proven reservoir potential is within the micro-biolite and coquinas formations which contain large hydrocarbon accumulations. The recent opening of this play fairway to unitization and bid rounds makes the PGS reprocessing effort timely and effective for exploiting these resources. As demonstrated with the examples below PGS can deliver high quality depth imaging using state-of-the-art seismic processing, velocity model building and advanced imaging technologies and workflows.
Final products for 45 000 sq. km are available now and an additional 6 000 sq. km will be available later in 2020.
