OSLO, Norway – PGS and the Angolan oil and gas agency ANPG have expanded the Angola MegaSurvey to include Block 16 PSTM GeoStreamer data.
Block 16 in the Lower Congo basin and others in the area have been included in Angola’s 2021 license round.
Last month the country’s 2020-2025 Hydrocarbon Exploration Strategy also secured approval under Presidential Decree No. 282/20.
According to PGS, the aim is to boost oil and gas exploration in order to counter the country’s declining production. In the short term, the focus is on exploration in development areas such as the Lower Congo basin.
The Block 16 GeoStreamer coverage adds a further 3,684 sq km (1,422 sq mi) of broadband data in the Lower Congo basin, with total coverage provide by the Angola MegaSurvey is now more than 45,000 sq km (17,375 sq mi).
Christine Roche, Sales Manager Africa Mediterranean and Middle East at PGS, said that several blocks covered by the expanded MegaSurvey dataset will be included in the 2021 round.
Main exploration targets are in various geological zones. The post-salt section contains the proven Miocene play with numerous producing oil fields.
The Upper Cretaceous section remains relatively underexplored, while the presalt section, set to become the focus of future exploration efforts, has so far only been drilled in the shallow water.
MegaSurveys comprise 3D data that have been re-binned to a common grid and then matched and merged to produce a phase-balanced, uniformly scaled, contiguous regional 3D dataset.
