Cape Anguille | PGS

Orphan Basin - Canada

Cape Anguille 3D GeoStreamer (In Processing)

Cape Anguille provides continuous coverage in the Orphan Basin, Eastern Newfoundland Region
Website Map for Survey Cape Anguille
The survey provides continuous data coverage in the Orphan Basin ahead of the Call for Bids in 2022 and 2024.
Potential reservoirs identified in the Tertiary and Cretaceous sections with evidence over the region for source rock and active petroleum systems.
Broadband 3D imaging will help identify all the necessary petroleum system elements contained in this underexplored basin. GeoStreamer data with AVO compliant processing will help de-risk exploration in this basin.
