Central Graben - Norway - 2013-2015

PGS15908CGR 3D GeoStreamer

Ideal dataset for detailed mapping of existing fields and exploration targets in this mature basin
Website Map for Survey PGS15908CGR
Long offset GeoStreamer acquisition that illuminates the deepest parts of the Central Graben and reveals interesting exploration targets on the basin flanks.
Well known mature hydrocarbon province with a wide spread of geological targets.
GeoStreamer provides the penetration needed for deep HPHT targets as well as resolution to map more subtle targets in the shallow. This broadband dataset is excellent for reliable QI inversion studies.
