Chevron shifts to execution in Orange Basin
Chevron is preparing to drill the Nabba-1X exploration well in late 2026 within Namibia’s offshore petroleum exploration licence (PEL) 90, marking the next phase of its exploration push in the Orange Basin.
The block is operated by Harmattan Energy Limited, which holds a 52.5% working interest, alongside QatarEnergy International E&P LLC with 27.5%. The remaining stakes are held by the National Petroleum Corporation of Namibia (NAMCOR) and Trago Energy, with 10% each.
The drilling plan was confirmed during the Namibia International Energy Conference 2026, where Chevron outlined its forthcoming steps in the country’s rapidly evolving offshore sector. Beatrice Bienvenu, Chevron’s Namibia country manager, stated that the company is transitioning from evaluation to execution.
"I am excited to share that Chevron is moving into the next phase of our exploration programme. Building on our insights, we expect to drill the Nabba-1X well in PEL 90 in late 2026," said Bienvenu.
"This next step is a testament to our confidence in Namibia’s offshore potential and our commitment to thoroughly testing our portfolio. We are here for the long term, and every well we drill strengthens our partnership with this country."
Investor confidence
The move positions Chevron among a growing list of international oil majors accelerating exploration activity offshore Namibia, following a string of major discoveries in the Orange Basin.
Mines minister Modestus Amutse, said the planned well reflects increasing investor confidence in Namibia’s resource base.
"Chevron’s decision to proceed with a second well in Namibia signals strong confidence in our resource base. The ongoing exploration activities reflect Namibia’s growing standing as a credible and competitive destination for responsible investment," said Amutse.
"The Namibian Government remains committed to constructive engagement with investors to ensure developments align with national interests and deliver meaningful benefits to our economy and our people."
Unlocking potential
Mtundeni Ndafyaalako, Acting MD of NAMCOR, said the Nabba-1X well will be central to unlocking the potential of the block.
"NAMCOR is proud to be part of the joint venture group in PEL 90. The planned Nabba-1X well is a key step in our mission to secure Namibia’s energy future and unlock the full potential of the Orange Basin," he said.
The planned drilling campaign underscores Namibia’s transition from frontier exploration to an increasingly active offshore province, as companies intensify efforts to test and commercialise resources across multiple licences in the basin.
