PGS16909NWS 3D GeoStreamer®

State-of-the-art imaging to streamline and optimize the E&P process
Website Map for Survey PGS16909NWS
The objective of the HUB upgrade is to generate one high quality dataset with modern demultiple, noise attenuation and depth imaging and deliver a seamless dataset for the entire area.
The area has numerous commercial oil and gas discoveries, primarily within Jurassic and Cretaceous reservoirs, and further exploration potential still exists. Further potential is seen within Paleogene, Upper Cretaceous and Triassic Grey and Red Beds and possibly Permian reservoir rocks.
A high quality seamless exploration dataset with the latest GeoStreamer processing flow for a better regional picture, including modern demultiple, noise attenuation and depth imaging on MC3D-HVG2011, MC3D-HVG2012, MC3D-HVG2013 and PGS14002.
