Chevron Reports Oil and Gas Condensate Discovery in Angola’s Block 0
Chevron Corporation, through its subsidiary Cabinda Gulf Oil Company Limited (CABGOC), has announced a new oil and gas condensate discovery at the 105-4X exploration well in Block 0, offshore Angola. The discovery adds to Chevron’s long-standing exploration and production presence in the country and highlights the company’s strategy of targeting resources that can potentially be developed using existing infrastructure.
The 105-4X well was drilled in the prolific Lower Congo Basin, one of Angola’s established hydrocarbon-producing regions. The exploration well encountered an oil and gas condensate column exceeding 600 meters, or approximately 2,000 feet, within the primary Pinda reservoir. The well also identified more than 90 meters, or about 300 feet, of net pay in reservoir rocks described as being of excellent quality.
The results provide Chevron and its partners with an opportunity to further evaluate the discovered resources and determine their commercial potential. One of the key advantages of the discovery is its proximity to Chevron’s existing offshore facilities. Subject to further technical and commercial evaluation, the resource could potentially be developed as a tie-back to nearby infrastructure.
A tie-back development could provide a capital-efficient route toward production because it may allow the company to utilize existing facilities, pipelines and associated infrastructure rather than requiring an entirely new standalone development. This approach is consistent with Chevron’s broader strategy of pursuing high-value exploration opportunities that can complement its established production portfolio.
“This discovery is another important milestone for Chevron’s over 70-year history in Angola,” said Kevin McLachlan, Vice President, Exploration, Chevron. He added that combining high-impact exploration with infrastructure-led opportunities close to existing facilities is helping the company expand its resource base, create value and demonstrate the effectiveness of its strategy.
McLachlan also emphasized Chevron’s continued confidence in Angola’s resource potential. The latest discovery reinforces the company’s view that established producing regions can continue to offer opportunities for resource additions through targeted exploration and appraisal activity.
Block 0 is operated by CABGOC, which holds a 39.2% working interest in the block. Sonangol E&P holds a 41% working interest, while TotalEnergies has a 10% interest and Azule Energy holds the remaining 9.8%. The partnership brings together major international and national energy companies with extensive experience in offshore exploration, development and production.
The discovery also forms part of Chevron’s broader exploration activities across Sub-Saharan Africa. The company currently produces approximately 300,000 barrels of oil equivalent per day net across the region, supported by a portfolio of established assets and ongoing exploration programs. Chevron believes its existing resource base, combined with new exploration opportunities, can help sustain and potentially increase production over the long term.
Over the past 12 months, Chevron has continued to expand and strengthen its exploration position in several countries across Sub-Saharan Africa. Nigeria has been a major focus of this strategy. The company farmed into two offshore blocks, PPL2000 and PPL2001, during the previous year and was subsequently awarded deepwater block PPL2010 during Nigeria’s latest bid round.
Chevron has also recorded several near-field exploration successes in Nigeria since late 2024. These include the Meji NW-1, South Delta AA and Awodi-07 discoveries. The company is continuing exploration and appraisal activities around these opportunities as it works to evaluate their resource potential and identify potential development pathways.
The company has also expanded its exploration footprint in Guinea-Bissau. Chevron has secured interests in three blocks in the country, including newly acquired Block 4B, for which the transaction closed on August 13, 2026. The addition further broadens Chevron’s position in West Africa and provides the company with additional acreage for future exploration.
In Equatorial Guinea, Chevron has secured five additional reconnaissance licenses. These licenses give the company the opportunity to evaluate prospective areas and identify potential exploration targets as part of its wider regional portfolio strategy.
Angola remains another important component of Chevron’s exploration program. In addition to the Block 0 discovery, the company is continuing exploration activities in Blocks 49 and 50, Block 33 and Block 14/23. These programs provide opportunities to test additional prospects and potentially identify resources that could contribute to future production.
Chevron’s regional exploration strategy is focused on combining established producing areas with frontier opportunities. The approach allows the company to pursue large-scale exploration prospects while also targeting discoveries located near existing infrastructure. The latter can potentially shorten development timelines and improve project economics by reducing the need for extensive new infrastructure.
The company is also preparing a high-impact, multi-well exploration program across Sub-Saharan Africa. One of the anticipated activities is the Nabba-1X exploration well in Namibia’s PEL90, which Chevron expects to drill before the end of 2026. The program demonstrates the company’s continued willingness to invest in exploration opportunities with the potential to deliver significant resource additions.
For Angola, the latest Block 0 discovery comes against the backdrop of the country’s efforts to maintain and expand its position as a major African oil and gas producer. Offshore Angola contains substantial hydrocarbon resources, and continued exploration around established producing areas can help extend the productive life of existing infrastructure and support future investment.
The 105-4X result therefore has significance beyond the size of the discovered hydrocarbon column. Its location within Block 0 and the potential to connect future production to nearby facilities could make the discovery an attractive candidate for further appraisal and development studies. Additional evaluation will be required to determine the size of the recoverable resource, reservoir performance, development requirements and overall economic viability.
Chevron’s latest announcement also demonstrates the company’s emphasis on disciplined capital allocation. Rather than relying exclusively on large standalone developments, the company is seeking opportunities where exploration success can be integrated with existing operations. Such infrastructure-led projects can potentially create additional production while limiting the capital and construction requirements associated with greenfield developments.
The discovery strengthens Chevron’s exploration portfolio at a time when the company is pursuing opportunities across multiple Sub-Saharan African markets. Angola, Nigeria, Guinea-Bissau, Equatorial Guinea and Namibia all feature in its broader regional strategy, giving Chevron exposure to both established petroleum basins and emerging exploration frontiers.
Overall, the 105-4X discovery represents another step in Chevron’s long-term presence in Angola. The combination of a substantial oil and gas condensate column, strong reservoir quality and proximity to existing facilities provides a foundation for further evaluation. As Chevron and its partners assess the discovery, the project could potentially contribute to future production while supporting the company’s objective of expanding its resource base through focused and high-impact exploration.
The company’s continued activity across Sub-Saharan Africa underscores its confidence in the region’s hydrocarbon potential. By pursuing a balanced portfolio of near-field discoveries, infrastructure-led opportunities and frontier exploration, Chevron is positioning itself to identify new resources and build long-term value while maintaining a disciplined approach to capital investment.
