Why Angola Is Regaining Upstream Investment Momentum
Angola’s upstream oil and gas sector is entering a recalibration phase that presents genuine opportunities for international operators, independents, and service companies. After years of declining output, fiscal rigidity, and bureaucratic inertia, the government in Luanda has enacted a series of structural reforms designed to arrest the production slide and attract fresh capital into exploration and development.
Production averaged approximately 1.13 million barrels per day in 2024, a far cry from the 2008 peak of nearly 2 million bpd. That decline trajectory, however, is precisely what has catalysed reform. Angola’s departure from OPEC in January 2024 removed quota constraints and signalled Luanda’s determination to prioritise volume growth over cartel politics. The question for investors is whether the fiscal, regulatory, and geological fundamentals now align to justify new capital deployment.
The answer, based on a detailed examination of recent licensing rounds, fiscal incentives, and operator commitments, is cautiously affirmative. This article maps the investment landscape across exploration acreage, development-stage assets, and mature-field reinvestment, providing the data points investors and executives need to evaluate Angola’s upstream proposition.
The Fiscal Reset: Presidential Decree 8/24 and Its Implications
The most consequential policy change underpinning Angola’s investment case is Presidential Decree 8/24, signed in early 2024. This decree reduced royalty rates to 15 percent for new developments and capped the Agencia Nacional de Petroleo, Gas e Biocombustiveis (ANPG) share of profit oil at 25 percent. For marginal and deepwater fields, additional incentives apply, including accelerated cost recovery and reduced state participation thresholds.
Under the prior regime, effective government takes on deepwater production sharing agreements frequently exceeded 70 percent over the project lifecycle, rendering marginal discoveries uneconomic. The new fiscal architecture brings Angola’s terms closer to those of Guyana, Namibia, and Mozambique, jurisdictions that have successfully attracted frontier investment in the 2020s.
ANPG, established in 2019 as the dedicated upstream regulator, has moved aggressively to standardise contract terms and accelerate licensing timelines. The agency’s 2025-2026 licensing strategy includes both competitive bid rounds and direct negotiation pathways for pre-qualified operators. For a full analysis of how these agreements are structured, see our guide to production sharing agreements in Angola.
Open Acreage and the 2025-2026 Licensing Rounds
Angola’s sedimentary basins, principally the Lower Congo, Kwanza, and Namibe basins, contain an estimated 55 billion barrels of original oil in place, of which only a fraction has been produced. Proved reserves stand at approximately 2.6 billion barrels, but probable and possible volumes are significantly higher, particularly in the under-explored onshore Kwanza and frontier Namibe basins.
ANPG launched a permanent offer system in 2023, making blocks available on a rolling basis rather than through periodic bid rounds. As of early 2026, more than 35 blocks are available across onshore, shallow-water, and deepwater tranches. Key blocks generating investor interest include:
- Kwanza Basin ultra-deepwater blocks (CON 1-6): Adjacent to TotalEnergies’ Kaminho discovery area. Water depths of 1,500 to 2,500 metres. Prospectivity supported by 3D seismic data indicating multiple pre-salt play types analogous to Brazil’s Santos Basin.
- Lower Congo Basin relinquished acreage: Several blocks returned by operators during the 2015-2020 downturn now carry updated seismic datasets and offer lower entry costs.
- Onshore Kwanza blocks: Early-stage exploration with frontier risk but significant upside. The government is offering enhanced fiscal terms for onshore operations, including reduced signature bonuses and extended exploration periods.
- Namibe Basin frontier blocks: The least explored of Angola’s offshore basins, positioned south of the Kwanza Basin. Geological analogies with Namibia’s Orange Basin, where TotalEnergies’ Venus discovery in 2022 confirmed a major light oil province, have heightened interest.
Shell’s return to Angola through a 17-block memorandum of understanding signed in October 2025, reportedly backed by approximately $1 billion in committed exploration expenditure, validates the prospectivity thesis. Shell had progressively divested Angolan assets during the 2010s; its re-entry signals a meaningful reassessment of the basin’s potential.

Deepwater Development: The Kaminho Catalyst
TotalEnergies’ final investment decision on the Kaminho project in May 2024, valued at approximately $6 billion, represents the largest single upstream commitment in Angola in over a decade. Located in Block 20/11 in the Kwanza Basin, Kaminho targets pre-salt carbonates at water depths exceeding 2,000 metres. First oil is expected around 2028, with plateau production projected at 70,000 bpd.
Kaminho is significant not merely for its volumes but for what it signals about deepwater pre-salt prospectivity in the Kwanza Basin. The geological play type mirrors the prolific pre-salt formations that have driven Brazil’s production growth since 2010. If Kaminho delivers at or above expectations, it could catalyse a wave of follow-on development decisions in adjacent blocks.
Beyond Kaminho, several other deepwater developments are advancing through the pipeline:
- Begonia (Block 17, TotalEnergies): A satellite development tied back to the Pazflor FPSO in the Lower Congo Basin. FID taken in 2022 with first oil achieved in late 2024.
- Ndungu (Block 15/06, Azule Energy): An infill development leveraging the existing FPSO Agogo, targeting incremental production of 30,000 bpd.
- Quiluma and Maboqueiro (Block 15/06, Azule Energy): Non-associated gas developments feeding into the Sanha Lean Gas Connection, which delivered first gas in December 2024.

Mature Field Reinvestment: The Overlooked Opportunity
While exploration and deepwater greenfield projects dominate headlines, mature field reinvestment represents a substantial and often under-appreciated investment category. Angola’s legacy fields in Blocks 0, 2, 3, and 14 in the Lower Congo Basin and Cabinda enclave have been producing for decades, with natural decline rates averaging 8 to 12 percent annually.
Chevron, which operates the Cabinda concession area through its subsidiary Cabinda Gulf Oil Company (CABGOC), has maintained output through aggressive infill drilling, waterflood optimisation, and well intervention campaigns. The Sanha Lean Gas Connection, which commenced operations in December 2024 with an initial capacity of 80 million standard cubic feet per day ramping to 300 mmscf/d, exemplifies how mature asset infrastructure can be repurposed to unlock stranded gas resources.
For smaller operators and service companies, mature field reinvestment offers several advantages: lower geological risk, established infrastructure, shorter time-to-revenue, and potentially favourable fiscal terms under the new incentive framework. ANPG has signalled interest in attracting mid-cap operators to mature blocks that majors may view as non-core. Our analysis of well intervention and workover activity examines the service market dynamics in this segment, while our feature on enhanced oil recovery techniques evaluates the technical potential for EOR in Angola’s mature reservoirs.
Key Operators and Their Strategic Positioning
Understanding the competitive landscape requires examining the strategies of Angola’s principal operators:
Sonangol, the state oil company, is undergoing a multi-year restructuring programme aimed at separating its commercial and regulatory functions. Sonangol retains equity stakes across virtually all producing blocks and is increasing its operated portfolio through farm-ins and direct awards. The company’s upstream ambitions are focused on building operatorship capability, particularly in shallow-water and onshore assets.
TotalEnergies remains the largest foreign operator by production volume, with interests spanning Blocks 17, 32, 14K, and the pivotal Block 20/11 (Kaminho). TotalEnergies’ integrated strategy combines upstream development with gas monetisation and renewable energy investments.
Azule Energy, the joint venture formed by BP and Eni in 2022, manages a combined portfolio that makes it one of Angola’s largest producers. Azule’s asset base spans Blocks 15/06, 17/06, 18, and the onshore Block 6(06), providing diversification across deepwater, shallow-water, and gas-weighted assets.
Chevron operates the Cabinda concession and holds interests in Blocks 0, 2, and 14, with a strategic focus on extending the productive life of mature assets while developing associated gas resources.
ExxonMobil holds interests in Block 15, home to the Kizomba complex, one of Angola’s most prolific deepwater developments. ExxonMobil’s near-term focus is on infill drilling and subsea tieback opportunities.
Shell’s re-entry through the 17-block MoU positions the company for a long-term exploration campaign, with initial seismic acquisition expected through 2026-2027.

Service Sector Opportunities
The upstream investment opportunity extends beyond equity participation in exploration and production. Angola’s service sector market, encompassing drilling, subsea engineering, logistics, and technical services, is poised for growth as development activity accelerates.
The country’s local content requirements, codified in the General Law of Local Content (Law 10/22), mandate minimum thresholds for Angolan workforce participation and procurement from domestic suppliers. International service companies entering the market typically do so through joint ventures with Angolan-owned enterprises. While these requirements add complexity, they also create partnership opportunities for firms with capabilities in deepwater drilling and subsea engineering.
Drilling rig demand is expected to increase through 2026-2028 as Kaminho and other deepwater developments enter their drilling phases. The current drillship fleet operating in Angolan waters includes units from Valaris, Transocean, Seadrill, and Diamond Offshore, with additional mobilisations anticipated as operator programmes ramp up.
Risk Factors and Due Diligence Considerations
No investment analysis is complete without an honest assessment of risks. Angola’s upstream sector carries several material risk factors:
Political and regulatory risk: While the current administration under President Joao Lourenco has prioritised economic reform, Angola remains a presidential republic with significant executive power concentration. Regulatory changes can occur via presidential decree without legislative deliberation.
Currency and transfer risk: The Angolan kwanza (AOA) has experienced significant depreciation over the past decade. Operators must navigate foreign exchange controls and ensure dollar-denominated revenue repatriation mechanisms are contractually secured.
Infrastructure constraints: Port capacity, aviation logistics, and fabrication yard availability can create bottlenecks during periods of high activity. The Luanda and Soyo logistics bases are the primary support hubs, with capacity expansions underway but not yet complete.
Geological risk: While the Lower Congo Basin is well characterised, the Kwanza and Namibe basins carry frontier exploration risk. Pre-salt plays, in particular, involve high well costs ($80-150 million per deepwater well) and binary outcomes.
Local content compliance: Meeting local content obligations requires advance planning and investment in workforce training and supplier development. Non-compliance can result in financial penalties and, in extreme cases, contract termination.

Conclusion: A Measured Case for Capital Deployment
Angola’s upstream sector in 2026 presents a more compelling investment proposition than at any point since the 2014 oil price crash. The fiscal reset under Decree 8/24, the ANPG’s proactive licensing strategy, Shell’s billion-dollar re-entry, and TotalEnergies’ Kaminho commitment collectively signal renewed confidence in the basin.
The opportunity set spans the full risk-return spectrum: from frontier exploration in the Namibe Basin (high risk, high reward) to mature field optimisation in Cabinda (lower risk, moderate returns). For a broader perspective on deal structures and capital flows, see our oil and gas investment opportunities 2026 outlook. Service companies face a growing market as drilling and development activity scales up through the decade.
Investors should approach Angola with clear-eyed recognition of the political, fiscal, and operational risks, while acknowledging that the structural reforms now in place have materially improved the risk-adjusted return profile. For those with the risk appetite and operational capability, Angola’s upstream sector offers a window of opportunity that the market has not yet fully priced.
