PGS15009 3D GeoStreamer®and EM

Illuminating the Veslekari Dome and the Bjarmeland Platform
Website Map for Survey PGS15009
This dataset provides additional coverage over structures on the flanks of the Bjarmeland Platform including the Veslekari Dome. 3D seismic is combined with high density 3D Towed Streamer EM data to gain greater certainty and understanding of exploration targets.
The survey is located in a frontier province opening up potential within the Jurassic level, possible analogs to Wisting.
Optimal 3D seismic acquisition configuration for Separated Wavefield Imaging. PGS also has high data density Towed Streamer EM (PGS15009EM) over the area allowing spatial delineation of prospects creating significant value.
