PGS releases data from Angola seismic survey

Beam migrated data is now available for viewing on PGS’ latest 3D GeoStreamer seismic survey over Angola blocks for the 2021 bid round. Modern imaging will unlock links between onshore and offshore presalt and postsalt plays.

“Our initial coverage of shallow blocks six to eight will allow interested E&P companies a head start on derisking prospectivity of the area ahead of bid submissions in 2021”, said Christine Roche, New Ventures Manager for PGS in Angola.

Commercial, strategic and technical benefits are available to early participants in the survey. Preferential license fee rates and early fast-track data deliverables are available for early participants.

A multi-year Angola License Round programme was recently announced during a series of License Round Roadshow events. The shallow-water shelf blocks of the Kwanza Basin present considerable remaining hydrocarbon potential. Past successes within shallow-water Kwanza include the Denden, Azul, Cegonha, Muamba, Pakubalu and Mubafo Fields, with reservoirs in both the presalt and the postsalt. Since 1993, just five exploration wells have been drilled on this acreage.

The multisensor 3D GeoStreamer data over the shallow-water shelf area of the Kwanza Basin, Angola, was acquired in 2019 in cooperation with the Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG).

The survey used a triple source configuration, with 12 x 8025 m streamers operating in fan mode and multisensor GeoStreamer technology. Following modern processing and imaging, these will provide clearer images with reliable attributes.
