The OCB has moved from frontier exploration to development planning, with TotalEnergies targeting a Venus FID in 2026 and appraising Mopane. Local-content and state-participation ambitions are watch points. Outlook: Positive.

Description

The ORCB is a volcanic rifted passive margin created by the break-up of the South American and African plates in the Late Jurassic/Early Cretaceous, followed by drifting and the opening of the South Atlantic Ocean. The early Aptian Kudu Shale, deposited in a restricted anoxic proto-South Atlantic, is the world-class source rock. Historic exploration focused inboard of the Outer High in shallow water, where the Kudu gas field (1974) was the main discovery. In 2022 Shell's Graff-1 and TotalEnergies' Venus-1X wells proved a deep-water light-oil system: Venus in Lower Cretaceous (Aptian–Albian) basin-floor fans and Graff in Upper Cretaceous turbidites. Galp's Mopane discoveries (2024) then extended the play inboard of the Outer High, establishing distinct outboard and inboard play fairways.

Summary

The OCB has moved from frontier exploration to development planning following the Venus, Mopane, Graff and Jonker discoveries. TotalEnergies now operates both Venus and Mopane, with a Venus FID targeted for 2026 (first oil c. 2029–30) and a three-well Mopane appraisal programme starting in H2 2026 ahead of a 2028 FID. High gas-oil ratios and cost discipline remain the key hurdles to sanction.
