Equinor Buys 17.4% of Namibia Deepwater Block PEL 90 From Chevron Subsidiary Harmattan, Joining QatarEnergy in Orange Basin
Equinor bought a 17.4% stake in Namibia's PEL 90 from Chevron unit Harmattan, completing three farm-outs that cut Chevron's interest from 90% to 35%.
Equinor has acquired a 17.4% participating interest in PEL 90, a 5,433-square-kilometre deepwater block in Namibia's Orange Basin, from Harmattan Energy Limited, an indirect wholly owned Namibian subsidiary of Chevron Corporation. The deal, announced August 18, positions Equinor alongside Chevron, QatarEnergy, Trago Energy, and state-owned NAMCOR in one of Africa's most actively drilled frontier basins.
Three Farm-Outs Cut Chevron's PEL 90 Stake From 90% to 35%
Chevron, through Harmattan, originally held a 90% working interest in PEL 90 alongside Trago Energy's 10% at the time of the block's licensing. Since then, Harmattan executed three successive farm-outs. First, QatarEnergy acquired a 27.5% participating interest, reducing Harmattan to 62.5%. Next, NAMCOR received a 10% carried interest, bringing Harmattan to 52.5%. The August farm-out to Equinor now places Harmattan at 35.1%.
Chevron retains operatorship of Block 2813B despite the stake reductions. That structure is deliberate: by selling interest tranches to QatarEnergy and Equinor, Chevron spreads exploration risk while keeping technical control of a frontier program. Post-deal, Chevron's Harmattan unit holds the block's largest single position at 35.1%. Philippe Mathieu, Equinor's EVP for Exploration and Production International, said the deal "aligns with our strategy to strengthen and replenish our international portfolio through focused and disciplined growth," according to the Equinor press release.
Kapana-1X Dry Hole Did Not Deter New Partners
Harmattan drilled the Kapana-1X exploration well in PEL 90 in January 2025. The well was a dry hole, finding no commercial hydrocarbons. Oil and Gas Journal reported the result at the time, noting the well finished 25% ahead of schedule.
Despite the Kapana result, QatarEnergy farmed into the block in mid-2025 and Equinor followed in August 2026. Sintana Energy, a Canadian junior that tracks Orange Basin activity, said the Kapana-1X results "increased confidence in the future program on PEL 90" by de-risking certain geological targets. Majors farming into a post-dry-hole block signal they see prospectivity in untested sections of the acreage, not a single-well write-off.
The block sits at water depths of 2,300 to 3,300 metres, placing it in ultra-deepwater territory. A single exploration well at those depths typically costs $150 to $200 million. Spreading that cost across five partners reduces Equinor's per-well exposure to roughly $26 to $35 million at its 17.4% share.
QatarEnergy Expands Upstream as Ras Laffan Remains Impaired
QatarEnergy's 27.5% stake is the largest non-operated interest in PEL 90. The NOC maintains that position while its domestic LNG operations remain under force majeure. As Oil Authority reported, QatarEnergy shipped just 18 LNG cargoes in the six months following missile strikes on Ras Laffan in March 2026, representing an estimated $20 billion in lost annual revenue.
QatarEnergy's simultaneous upstream expansion reflects a long-cycle strategy that runs independently of near-term LNG disruption. Orange Basin deepwater wells would not produce first oil before the early 2030s. The NOC is securing decade-out production optionality at a point when its Ras Laffan recovery timeline remains uncertain.
Market Context: Brent at $88 Supports the Long-Cycle Case
Brent crude closed at $88.10 per barrel on Friday's ICE settlement, per Yahoo Finance data for the BZ=F front-month contract. WTI settled at $83.40 per barrel on the CME. Goldman Sachs projects Brent will average $75 per barrel in 2027, its current base case; Wood Mackenzie holds a slightly higher 2027 forecast of $78 per barrel.
Even the Goldman bear case exceeds the typical deepwater breakeven of $40 to $55 per barrel for comparable ultra-deepwater Orange Basin development. Both forecasts support a long-cycle investment decision. The PEL 90 farm-in remains subject to Namibian regulatory approval before it closes.
