PGS19M02NWS 3D GeoStreamer® (In Acquisition)

Exciting frontier acreage on Trøndelag Platform and Helgeland Basin close to existing infrastucture
Website Map for Survey PGS19002NWS
This 2019 regional 3D GeoStreamer survey is acquired with a triple source to maximize data density. The results will allow to unlock the potential of a highly underexplored area that is perfectly positioned to bring resources quickly to market.
The area has mainly Jurassic targets, but it could also have potential in unproven presalt plays in the Permian.
Integrated Complete Wavefield Imaging of GeoStreamer data will allow detailed prospect evaluation and exploration for new plays. The superior AVO compliant dataset will be delivered ready for rigorous rock physics interrogations.
