South Africa’s offshore energy future sharpened into focus in May 2026, when Navitas Petroleum farmed into Block 1 CBK in the Orange Basin, triggering a resource reassessment that now puts the block’s unrisked prospective oil resources at more than 3.6 billion barrels and its prospective gas resources at approximately 4.5 trillion cubic feet.
Those are large numbers. What they mean for ordinary South Africans depends almost entirely on what happens next.
Eco Atlantic Oil & Gas and Navitas Petroleum, the block’s partners, based the updated estimates on existing seismic data, with additional interpretation still underway as both companies continue evaluating development options. The figures are prospective, not proven, and the path from seismic interpretation to production is long. Even so, the scale of the resource assessment has drawn attention from the African Energy Chamber, a regional industry body that has publicly backed sustained international investment in South Africa’s offshore sector.
NJ Ayuk, Executive Chairman of the Chamber, framed the opportunity in direct terms: “South Africa has an opportunity to turn its offshore resource potential into investment, energy security, jobs and economic growth, and we support companies that are prepared to commit capital and technical expertise to that opportunity.” He added that investors require confidence in regulatory clarity and efficiency, and that “South Africa can attract significantly more exploration capital if it provides the certainty required to move projects forward while maintaining strong environmental standards.”
That last phrase carries real weight for citizens. Energy security and job creation are the headline promises of offshore development, but they arrive only if environmental safeguards hold and regulatory conditions remain stable enough to see projects through to production. The Chamber has been explicit that unlocking the Orange Basin’s potential requires not just exploration capital but a predictable framework that enables responsible projects to advance.
Meanwhile, the Block 1 CBK work sits within a broader strategic relationship between Eco and Navitas that extends across the Atlantic Margin. In the Falkland Islands, Navitas has identified a 2U prospective resource of approximately 640 million barrels of oil at its first selected drilling target on PL001 in the North Falkland Basin. Subject to completion of Eco’s acquisition of JHI Associates, Eco’s share of that resource would be approximately 225 million barrels in a drilling-success case. Navitas intends to drill a multi-target exploration well on PL001 as part of its North Falkland Basin campaign, with drilling associated with the Sea Lion project expected to begin in early 2027.
Eco CEO Gil Holzman described Navitas’ updated assessment of Block 1 CBK as evidence of the block’s quality and its capacity to contribute to South Africa’s energy security while attracting international capital. Holzman also pointed to Eco’s existing experience in South Africa and neighboring Namibia, where the company has pursued offshore exploration opportunities, as context for the partnership’s regional ambitions.
For South Africans living with persistent energy challenges, the timing of these resource updates is not incidental. Offshore development on this scale could, in principle, reduce the country’s dependence on imported energy and generate employment across technical and support sectors. But that outcome is not automatic. It requires government authorities to manage the regulatory environment with both efficiency and rigor, ensuring that the pace of development does not outrun the environmental protections that communities along the coastline and beyond have a legitimate stake in.
The African Energy Chamber’s position is that international confidence in South Africa’s offshore sector is growing. The updated Block 1 CBK estimates reinforce that view.

The open question now is whether the regulatory framework will move at a pace that matches investor appetite, and whether the public interest conditions attached to that investment will be enforced with the same urgency as the commercial ones.
