Angolan oil tycoon Alberto Almeida de Sousa is searching for a deepwater partner to seal his Chevron block deal

Angola's largest private oil company is searching for an experienced deepwater operator to partner with it on a bid to acquire offshore assets that Chevron has agreed to sell, as it works to satisfy technical requirements tied to its pre-emption of a $260 million deal struck with London-listed Energean.

Etu Energias, controlled by former Sonangol executives Alberto Almeida de Sousa, Ana da Conceição Nunes and Alexandre Salgado Costa, invoked its contractual pre-emption rights after Energean announced in March 2026 that it had agreed to acquire Chevron's 31 percent operated stake in Block 14 and a 15.5 percent non-operated interest in Block 14K in Angola's Lower Congo Basin. Almeida de Sousa, who holds a 50 percent stake in Etu Energias and previously served as head of the geophysics division at Sonangol, is the company's largest shareholder.

The Energean deal included contingent payments of up to $250 million linked to production performance through 2038, bringing the total potential transaction value to $510 million. It was Energean's first venture into sub-Saharan Africa, a significant geographic expansion for a firm that had built its portfolio around gas assets in the Eastern Mediterranean.

Etu Energias faces a specific technical hurdle that is proving the most consequential part of the pre-emption process. Public filings tied to the proposed transaction require a replacement buyer to demonstrate proven experience operating producing deepwater assets in water depths exceeding 300 metres. The Chevron blocks in question are mature offshore producing assets that require advanced engineering and specialised operational expertise that Etu Energias has been working to build but has not yet fully established at the scale the technical requirements demand.

The company is now actively seeking an experienced deepwater operator to partner with it on the bid. The right partner would satisfy the technical criteria while Etu Energias brings its balance sheet, its pre-emption rights and its institutional knowledge of the Angolan upstream to the table. Industry observers say securing such a partner would significantly improve the company's chances of completing the acquisition and would deepen the operational capability it has been building since the Galp acquisition gave it exposure to Angola's ultra-deepwater sector.

Energean has acknowledged the pre-emption claim and confirmed that its sale agreement with Chevron remains effective until any pre-emption process is completed and a new agreement is executed. Chevron has not publicly indicated whether Etu Energias has met all conditions required to replace Energean in the transaction.

Etu Energias was established in 2000 as Somoil. The company has more than doubled its operated production since 2021. It operates Block 2/05 offshore, which contains 18 oilfields with combined reserves exceeding 500 million barrels, alongside multiple onshore blocks and has a growing portfolio of interests acquired from international majors. The rebrand from Somoil to Etu Energias, which stands for Energy, Transparency and Union and is also a Bantu word meaning "you and me together," signalled a strategic transformation into a full-cycle energy business with ambitions in deepwater operations and the broader African energy market.

The company signed a separate agreement with Azule Energy earlier in 2026 to acquire additional interests in Blocks 14 and 14K, adding to its presence in the same offshore region where the Chevron assets are located. If the Chevron pre-emption succeeds, Etu would consolidate a significant position in one of Angola's most established offshore producing areas, generating immediate cash flow from existing infrastructure while extending the productive life of mature reservoirs.

The stakes of the current process extend beyond Etu Energias. Angola has made increasing domestic participation in its oil sector a stated policy objective, and the government has been consistent in its support for indigenous companies acquiring producing fields that international majors are selling. Etu Energias sits at the centre of that policy as the country's largest private oil company, founded by former Sonangol executives who built their careers inside the state system before building a private alternative.

The contest over Chevron's interests illustrates both the opportunities and the challenges facing indigenous operators across Africa. Financial capacity alone is no longer sufficient in transactions involving technically demanding offshore developments where operational experience is considered essential by sellers and regulators alike.

Almeida de Sousa and his co-shareholders have positioned Etu Energias as Angola's answer to that challenge. Whether they can satisfy the deepwater operating requirement that stands between them and the Chevron assets will determine how far that ambition can go.
