In cooperation with the Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG), PGS is acquiring a new survey over the shallow-water shelf area of the Kwanza Basin, Angola. Acquisition commenced in Q1 2019 and is expected to be completed by the end of the year.

Representatives of the ANPG and Sonangol attended a start-up meeting on-board the Ramform Sovereign whilst it was in the port of Luanda. During the visit, they received a vessel tour and were able to learn about the equipment on-board and discuss the planned acquisition with the PGS crew. The survey configuration uses triple source with 12 x 8 025 m streamers operating in fan mode and multisensor GeoStreamer technology and will provide clearer images with reliable attributes.

Industry interest in these underexplored blocks has grown with news of their inclusion in the recently announced License Rounds. Blocks 7 and 8 will be offered by public tender in 2021. This new survey will allow companies to derisk prospectivity ahead of bid submissions.

The shallow-water shelfal blocks of the Kwanza Basin have been overlooked in recent exploration cycles and thus 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 and acreage has remained unlicensed for much of this period.

Commercial, strategic and technical benefits are available to early participants in the survey. Preferential license fee rates are presently being offered for pre-funding clients who will benefit from early fast-track data deliverables.
