PGS19M05VIK GeoStreamer X 3D GeoStreamer

GeoStreamer X redefines multi-azimuth data as a faster and smarter solution than nodes
Website Map for Survey PGS19M05VIK
This advanced high-density multi-azimuth solution is complementary to existing GeoStreamer coverage. GeoStreamer X provides high-end exploration data to resolve the imaging challenges present in the Viking Graben and reveal the remaining potential.
The area is known for good-quality hydrocarbon reservoirs and complex geology. Late Jurassic rifting led to the formation of numerous horsts and rotated fault blocks along the margins of the Viking Graben. Play types ranging from sand injectites, deep marine fans, carbonates and fractured basement.
GeoStreamer X utilizes the latest PGS' acquisition innovations by combining multisensor broadband fidelity with multi-azimuth illumination, wide-tow sources and dense streamer spacing for improved near-offset distribution, and long streamers for accurate velocity model building.
