Equinor Enters Namibia's Orange Basin via Chevron Subsidiary, Takes 17.4% Stake in Drill-Ready PEL 90

Equinor made its Namibia debut on August 18, acquiring a 17.4% participating interest in Petroleum Exploration Licence 90 (PEL 90), Block 2813B, in the deepwater Orange Basin. The company purchased the stake directly from Harmattan Energy Limited, a wholly owned Namibia subsidiary of Chevron Corporation.

Why Harmattan Energy Matters to the Deal Structure

Harmattan Energy is Chevron's incorporated operating vehicle in Namibia. Before the transaction, Harmattan held 52.5% of PEL 90. After selling 17.4% to Equinor, Harmattan retains 35.1% and remains operator. Wire headlines typically name only Chevron; the acquisition was structured through the subsidiary, which holds all Chevron's rights in the block. QatarEnergy holds 27.5%, Trago Energy 10%, and the state oil company NAMCOR 10%, bringing the post-transaction consortium to 100%.

The deal remains subject to regulatory approval and customary closing procedures. Neither Equinor nor Chevron disclosed financial terms.

A Drill-Ready Prospect as the Orange Basin Heats Up

PEL 90 holds a prospect that Equinor describes as drill-ready, with a well test planned before the end of 2026. The Orange Basin has attracted TotalEnergies, Shell, Galp, QatarEnergy, and now Equinor and Chevron in parallel licences over the past three years. TotalEnergies' Venus-1X discovery holds an estimated 3 billion barrels of oil in place. Phase 1 of a Venus development would recover an estimated 750 million barrels, with first oil targeted around 2030, pending a final investment decision TotalEnergies aims to reach by year-end 2026.

Galp Energia's Mopane field, recognized as the 2025 exploration discovery of the year by Africa Oil and Gas Report, carries resource estimates as high as 10 billion barrels in place. In July 2026, Namibia's Ministry of Industries, Mines and Energy approved a TotalEnergies-Galp asset swap that handed TotalEnergies operatorship of both Venus and Mopane. That consolidation puts two of the basin's largest discoveries under a single operator, opening a path to a faster FID on Venus.

Equinor's Strategic Rationale

Philippe Mathieu, Equinor's executive vice president for Exploration and Production International, described the transaction as aligned with the company's strategy to "strengthen and replenish our international portfolio through focused and disciplined growth." He added that it "complements our broader Atlantic Margin position." Equinor already operates deepwater assets in Norway, Brazil, and Tanzania across that margin.

Namibia builds on a run of portfolio moves visible in Equinor's NCS exploration alliance with Aker BP and Var Energi and its 15-year Troll gas supply contract with Uniper. The NCS moves target reserve replacement on the Norwegian Continental Shelf. Namibia targets basin-scale exploration upside on the opposite side of the Atlantic Margin.

What Equinor's 17.4% Could Be Worth

Oil Authority derived the following estimate from public data. If PEL 90 yields a discovery at the scale of Venus phase 1, Equinor's 17.4% working interest in 750 million recoverable barrels yields a gross entitlement of 130 million barrels. Spread across a 15-year production plateau, that represents roughly 24,000 barrels per day attributable to Equinor's account. The 2026 well test will determine whether such a resource base exists.

Namibia's total output potential, if multiple Orange Basin licences reach FID, could approach 700,000 barrels per day by the mid-2030s, according to African Energy Council projections. That would place Namibia among the top five crude producers in sub-Saharan Africa. Guyana's Stabroek block offers the most instructive parallel: ExxonMobil's programme there, covered in Oil Authority's report on the Errea Wittu FPSO deployment, pushed Guyana past 1 million barrels per day within a decade of the 2015 Liza discovery.
