PGS said on Thursday that the total GeoStreamer coverage in Blocks 6, 7, and 8 and the surrounding areas of the Kwanza Shelf is now 8,300 square kilometers.

This MC3D Kwanza Shelf survey complements PGS’ earlier acquisition, carried out in 2019 in cooperation with Sonangol.

According to the seismic company, the latest Kwanza Shelf survey will provide key data for the Angolan 2021 License Round and the fast-track dataset is now available for viewing.

PGS stated that the present-day shelf of the Kwanza Basin had been overlooked in previous exploration cycles and that the combination of 3D GeoStreamer technology with modern imaging techniques was expected to unlock plays in shallow Kwanza Shelf open blocks.

Shallow-water environments such as the Kwanza Shelf, PGS said, could present imaging challenges. These are resolved in this survey by enhanced processing flows such as FWI and SWIM enabled by high-quality GeoStreamer 3D broadband data.

Christine Roche, new ventures manager for Africa at PGS, stated: “High-density GeoStreamer acquisition, combined with the latest processing and imaging technology provide a detailed view of the hydrocarbon potential of the Kwanza Shelf area.

“This high-quality dataset will allow for lead and prospect generation, attribute analysis and reservoir-scale evaluations.”
