Norwegian Barents Sea - Norway - 2014

ST14005 3D GeoStreamer®

Illuminate targets on the Bjarmeland Platform
Website Map for Survey ST14005
This survey is a combined industry effort in an area previously closed to exploration. Combined seismic and 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. High data density 3D EM allows spatial delineation of prospects creating significant value.
The seismic was acquired with long offsets in order to illuminate deep targets and get sufficient offset coverage for AVO analysis. PGS has run CWI and SWIM® processing flows on the dataset. PGS also acquired Towed Streamer EM over the same polygon (PGS14250).
