TGS increases 3D seismic library offshore northwest Australia
TGS has completed the purchase of the Capreolus 3D seismic survey from Polarcus.
The Capreolus, full broadband 3D seismic survey is 22,130 sq km (8,544 sq mi) and covers two hydrocarbon provinces with proven, but underexplored, oil and gas plays both in the Beagle and Bedout sub-basins offshore northwest Australia.
The survey includes modern 3D coverage over thePhoenix South and Roc oil and gas discoveries. It also spans the Dorado-1 exploration well and Phoenix South-3 appraisal well, currently being drilled. Dorado-1 has encountered light oil in the Caley Member and gas/condensate in the Baxter Member and as of today, light oil has been confirmed at the deeper Crespin and Milne Members.
TGS also has started reprocessing the Australian Polly 3D seismic survey and neighboring open file data. Acquired in 2013, the Polly 3D covers 7,970 sq km (3,077 sq mi) and ties into the adjacent Capreolus 3D survey. The Polly 3D is being reprocessed using the latest broadband PSDM techniques with reprocessed products available from November 2018.
CEO Kristian Johansen said: “The combination of the Capreolus 3D with the neighboring reprocessed Polly 3D dataset provides E&P companies with modern contiguous 3D data linking the current Dorado-1 oil discovery to the acreage release blocks W18-4 and W18-5 currently on offer.”
