PGS20M05VIK GeoStreamer X 3D GeoStreamer (In Acquisition)

GeoStreamer X redefines multi-azimuth data as a faster and smarter solution than nodes
Website Map for Survey PGS20005VIK
This advanced high-density multi-azimuth solution is complementary to existing GeoStreamer coverage. GeoStreamer X will provide high-end seismic data suited to resolve the imaging challenges present in the Viking Graben and reveal the remaining potential
The area is known for its prolific source rock and good-quality reservoirs. Late Jurassic rifting led to the formation of numerous horst and rotated fault blocks along the margin of the Viking Graben. Targets range from Eocene injectites, deepmarine fans, fluvial deposits to weathered basement
GeoStreamer X utilizes the latest PGS' acquisition and Imaging innovations and are combining multisensor broadband fidelity with multi-azimuth illumination, wide-tow sources and dense streamer spacing for improved near-offset distribution, and long streamer for accurate velocity model building.
