ANG Blk 16 3D GeoStreamer®

3 684 sq. km of GeoStreamer data between prolific producing fields
Website Map for Survey ANG 16 MC3D
This dataset over Block 16 in Angola supports further exploration of the hydrocarbon potential of an offshore area which is surrounded by numerous oil and gas discoveries.
Data quality is high and designed to expand understanding of the geological framework and hydrocarbon potential of Block 16. It also adds a new dimension to knowledge already gained from producing fields in Block 15 to the north, and Block 17 to the south.
