<h1>Benguela Belize - Lobito Tomboco Oil Project,Angola</h1>

<h2>Overview</h2>
<p>The Benguela Belize–Lobito Tomboco Oil Project (BBLT) is an operating offshore conventional oil development in Block 14,Angola. The project combines the Benguela,Belize,Lobito,and Tomboco fields and is operated by Chevron. Ownership is held by Chevron Corp (31&#37;),Sonangol EP (20&#37;),Eni SpA (20&#37;),TotalEnergies SE (20&#37;),and Somoil Internacional de Petróleo do Brasil Ltda (9&#37;). BBLT is known for its compliant piled tower production hub,the first such structure installed outside the U.S. Gulf of Mexico. The development was executed in two phases: Phase 1 (Benguela Belize) built an integrated drilling and production platform on the compliant tower,and Phase 2 (Lobito Tomboco) added subsea wells tied back to the central hub.</p>

<h2>Location</h2>
<p>BBLT is located offshore Angola in Block 14,approximately 50–60 miles from the Cabinda coast in water depths of about 1,300 feet. The development is in the deepwater portion of the northern Angolan offshore province,commonly associated with the Lower Congo Basin,though project-specific basin data is not explicitly provided.</p>

<h2>Ownership and Operatorship</h2>
<p>Chevron operates the project through its subsidiary Cabinda Gulf Oil Company. The ownership structure reflects a typical Angolan offshore consortium,with Chevron as the largest equity holder and operator,alongside international participants Eni and TotalEnergies,national company Sonangol,and independent Somoil. This partnership model is standard for deepwater blocks in Angola.</p>

<h2>Development History</h2>
<p>Chevron announced first oil from the Benguela Belize phase in January 2005. The compliant piled tower platform was installed in Block 14,supporting an integrated drilling and production topsides weighing over 40,000 tons. The Lobito Tomboco phase followed as a subsea tieback to the central hub,allowing the four fields to be produced through a common facility. Public sources do not provide a single discovery or final investment decision year for the combined project. The project has been in production since the mid-2000s and remains operating as of 2022.</p>

<h2>Infrastructure and Facilities</h2>
<p>BBLT’s central production hub is a compliant piled tower,the first such deepwater structure outside the U.S. Gulf of Mexico. The tower supports a large topsides with a design capacity of 220,000 barrels per day. The Lobito Tomboco phase uses subsea wells tied back to the hub. The total project cost was reported at USD 2.2 billion. No recent public details are available on current well counts,subsea infrastructure condition,or maintenance history.</p>

<h2>Production and Reserves</h2>
<p>Global Energy Monitor reports a historic project-level production figure of 73.0 million barrels of oil for 2008. The design capacity of the Benguela Belize platform is 220,000 barrels per day. Current project-specific production rates are not confirmed in available sources. Block 14 as a whole was described by Energean in 2026 as producing approximately 40,000 barrels per day gross from nine fields,but this figure includes fields beyond BBLT. Project-level reserves and remaining recoverable volumes are not disclosed.</p>

<h2>Recent Developments</h2>
<p>In May 2025,a fire occurred on the cellar deck of the BBLT platform. Chevron reported one person missing and 17 injured. Production had been shut down since May 1 before the incident; the cause remained under investigation. Separately,Energean announced entry into Angola through acquisition of interests in Block 14 assets,though project-level ownership of BBLT remains as listed.</p>
