PGS releases data offshore Brazil, Namibia and Angola

Fast-track PSDM products are now available from the PGS’ Campos deepwater GeoStreamer X MultiClient 3D survey over Blocks C-M-350, C-M-417, and C-M-485 offshore Brazil. 

PGS said the new data are the first 3D seismic products delivered over this area, allowing Brazil’s 17th Round participants to evaluate this acreage prior to the bid round, scheduled for October 2021. 

Fast-track anisotropic (TTI) PSDM products are now available and include Kirchhoff and RTM stacks and gathers. In addition, final processed gravity and magnetic products are also available over the larger Campos Deepwater GSX programme. 

PGS’ Campos Deepwater GeoStreamer MC3D project was acquired in 2020 and 2021 with 10km-long offsets to improve depth velocity modelling accuracy of the postsalt, salt, and presalt sections. 

Meanwhile, Final PSTM and PSDM products are now available from PGS’ latest multi-client 3D surveys in the Namibe Basin offshore Angola and Namibia. 

New 3D GeoStreamer data brings fresh understanding for exploration in deepwater Blocks 29, 30, 44, and 45 in Angola, and Blocks 1710, 1711, 1810, and 1811A in Namibia. 

PGS’ ANG Namibe 2020 3D Geostreamer dataset targets more than 14,000 km2, adjacent to the ANG Namibe 2014 3D survey. The NAM 2019 3D GeoStreamer survey covers more than 8900 km2 of exploration acreage in the Namibian sector of the basin. 

PGS now offers continuous coverage of the southern Namibe basin, with final products comprising more than 34,000 km2 of broadband seismic data, tying into important exploration and ODP wells. 

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, said PGS. 

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, it added.
