ExxonMobil and its partners have committed approximately $1 billion to the Usan Infill Project in Oil Mining Lease (OML) 138, offshore Nigeria. This development marks a notable return to drilling activity by the company’s affiliate, Esso Exploration and Production Nigeria, after nearly a decade without new wells (last in 2016). The project is expected to add up to 40,000 barrels per day (bpd) of crude oil production, with first oil targeted within 18 months.
Project Details and Timeline
The Usan field, which started production in 2012, is a deepwater asset operated by Esso under a production-sharing contract (PSC) with NNPC Ltd. Partners include entities linked to Chevron, TotalEnergies, and CNOOC (or Nexen). Seismic data analysis identified additional opportunities, enabling this infill drilling campaign to tap untapped reserves and enhance output from the existing Usan Floating Production Storage and Offloading (FPSO) facility.
On-block activities are set to commence soon, following earlier commitments (around $300 million for preparatory work). This short-cycle investment focuses on near-term production growth rather than entirely new infrastructure.
Direct Economic Impacts
Increased Oil Production and Revenue: Nigeria relies heavily on oil for foreign exchange earnings and government revenue (often 50-70% of the federal budget in recent years, depending on prices). Adding 40,000 bpd represents a meaningful uplift—potentially contributing hundreds of millions in annual revenue at current oil prices, through royalties, taxes, and profit oil shares under the PSC. This helps offset declines from aging fields, theft, and infrastructure issues.
Foreign Direct Investment (FDI) and Investor Confidence: The project signals renewed international confidence in Nigeria’s offshore sector, especially after ExxonMobil’s onshore divestments. It forms part of broader deepwater plans (including Erha and potential Owowo developments), with cumulative commitments in OML 138 reaching around $17 billion. Such investments attract more capital, stabilize the naira, and support reserves.
Employment and Local Content: Construction, drilling, and operations will create direct and indirect jobs for Nigerians. The Nigerian Content Development and Monitoring Board (NCDMB) framework ensures local participation in services, fabrication, and skills development. Multiplier effects benefit suppliers, logistics, and communities in coastal areas.

Technology Transfer and Infrastructure: Deepwater projects bring advanced seismic, drilling, and production technologies. This enhances local capabilities and supports long-term sector growth.
Broader Macroeconomic Benefits
GDP Growth: Oil and gas contribute substantially to Nigeria’s GDP. Higher output supports related sectors like manufacturing, services, and transport.
Balance of Payments: Increased exports improve the current account and help fund imports and debt servicing.
Fiscal Space: Extra revenue allows more spending on infrastructure, education, and diversification efforts (e.g., gas commercialization or renewables), though prudent management is essential to avoid Dutch disease.
Energy Security and Multiplier Effects: Sustained production aids domestic refining ambitions and gas supply, while signaling stability that benefits non-oil FDI.
Challenges and Context
Nigeria aims to raise production toward 2+ million bpd amid global energy transitions and domestic issues like pipeline vandalism. This project addresses near-term gaps efficiently using existing FPSO assets.
However, benefits depend on oil price stability, transparent revenue management (e.g., via the Nigeria Sovereign Investment Authority), and addressing security and regulatory hurdles.
NUPRC Chief Executive Oritsemeyiwa Eyesan described it as a milestone for sector revival, while ExxonMobil’s Nigeria MD Jagir Baxi highlighted it as part of a long-term deepwater focus.
ExxonMobil’s $1 billion Usan Infill Project is more than an oilfield development—it is a strategic vote of confidence in Nigeria’s energy future. By delivering quick production gains, jobs, and revenue, it strengthens the economy in the short term while laying groundwork for sustained deepwater growth. Realizing full benefits will require effective local content implementation, revenue transparency, and complementary reforms to diversify beyond oil. In a challenging global and domestic environment, such investments are vital for Nigeria’s economic resilience and ambition.
