OSLO, Norway – PGS has released final PSTM and PSDM products from its latest multi-client 3D surveys in the Namibe basin offshore Angola and Namibia.
New 3D GeoStreamer seismic coverage brings fresh understanding for exploration in deepwater blocks 29, 30, 44, and 45 in Angola, and blocks 1710, 1711, 1810, and 1811A in Namibia.
The company’s ANG Namibe 2020 3D GeoStreamer dataset targets more than 14,000 sq km (5,405 sq mi), adjacent to the ANG Namibe 2014 3D survey. The NAM 2019 3D GeoStreamer survey covers more than 8,900 sq km (3,436 sq mi) of exploration acreage in the Namibian sector of the basin.

This final PSDM full-stack line from the ANG Namibe 2020 3D GeoStreamer survey demonstrates the high quality of the imaging, showing (1) early post-rift basin-fill containing widespread soft events (candidate source rocks), and (2) overlying interpreted clastic fairways pinching out up-dip.
It now offers continuous coverage of the southern Namibe basin, with final products comprising more than 34,000 sq km (13,127 sq mi) of high-quality broadband seismic data, tying into important exploration and ODP wells.

A final PSDM full-stack line from the NAM 2019 3D GeoStreamer survey offers imaging of (1) deep structuration and basin fill, and (2) thick prognosed clastic fairway identified in potential structural and stratigraphic trapping configurations.
Regional 3D GeoStreamer data, incorporating FWI velocity model building, will help to establish target plays and traps in the southern Namibe basin through better imaging of structure and basin fill, the company said.
Basin-wide broadband coverage enables the mapping of Cretaceous through to Tertiary play elements in a basin framework, facilitating the identification of sweet spots and derisking further exploration.
