NNPC, Partners Expedite $21bn Bonga Project
The Nigerian National Petroleum Company Limited and its international partners took a major step toward developing the $21 billion Bonga Southwest/Aparo deepwater project on Monday, 24 August 2026. State oil executives met in Abuja with representatives from Shell, ExxonMobil’s Esso exploration unit, and Eni’s Agip subsidiary to sign addenda to the Oil Mining Lease 118 Production Sharing Contract and Dispute Settlement Agreement. The formal pact establishes long-sought fiscal and commercial terms to push the long-delayed offshore asset toward a Final Investment Decision. Discovered twenty-five years ago, the field spans deepwater acreage across OML 118, OML 140, and OML 132 in the offshore Niger Delta. When operational, the field is expected to deliver peak output of 175,000 barrels of crude oil per day alongside 140 million standard cubic feet of natural gas. Nigeria desperately needs this new offshore production to arrest a decade-long stagnation in national output. Prolonged commercial disputes have kept these vast reserves locked under deep water for a quarter of a century.

The breakthrough follows President Bola Tinubu’s recent signing of the Deep Offshore Oil and Gas Projects Incentives Order, which slashed tax liabilities to attract deepwater capital. Group Chief Executive Officer of NNPC, Bashir Bayo Ojulari, noted that the fresh addenda prove how government fiscal reforms translate directly into project commitments. For years, international energy majors withheld final capital commitments from Nigerian waters because rigid fiscal terms made deepwater extraction unprofitable. Drilling in ultra-deep waters requires billions of dollars in upfront spending on floating production storage and offloading vessels, subsea manifolds, and export flowlines. Oil companies refused to sink that money into Nigeria while more attractive, low-tax basins in Guyana and Namibia competed for mobile exploration budgets. The revised tax remissions provide the long-term investment stability that global energy boards require. Tax relief has finally broken a twenty-year boardroom deadlock.
The operating consortium confirmed the successful completion of the pre-front-end engineering design phase, paving the way for full front-end engineering design studies. Commercial tenders have already identified a preferred bidder for the project’s central floating production storage and offloading vessel. However, formal engineering, procurement, construction, and installation contracts remain subject to final partner reviews and regulatory approvals. These technical design phases will define the exact layout of underwater wells and gas reinjection systems needed to tap complex reservoir formations. Moving into detailed engineering represents the most significant technical progress on the asset since the original Bonga field began pumping crude in 2005. The engineering contracts will also test the capacity of domestic fabrication yards in Lagos and Port Harcourt to handle heavy marine structures. Project planners must ensure that local yards receive real engineering work rather than token administrative subcontracts.
Securing fresh deepwater barrels has become an urgent priority as onshore and shallow-water fields suffer from severe natural depletion. Nigeria has struggled to meet its official output quotas, pumping far below installed technical capacity over the past five years. Onshore fields across the Niger Delta face relentless pipeline vandalism, illegal bunkering, and communal unrest that routinely shut down export trunklines. Deepwater platforms situated over one hundred kilometres offshore offer natural immunity against the bunkerers and vandals who plague onshore swamps. By shifting the bulk of national output into deep marine waters, energy planners can protect state export revenues from land-based sabotage. Offshore rigs pump uninterrupted crude straight into international export tankers without touching vulnerable onshore pipe networks. Deepwater crude provides the state with its most secure revenue stream.
The project promises a massive injection of foreign currency into an economy trying to rebuild its gross external reserves. Over its multi-decade lifespan, the Bonga Southwest development could funnel up to $21 billion in capital contracts, operating expenses, and tax royalties into national accounts. Local content laws require operating consortia to source fabrication steel, subsea engineering services, and marine logistics from registered Nigerian firms. Industry analysts estimate that developing the offshore field will generate thousands of specialised jobs for local welders, marine engineers, and logistics specialists. The influx of offshore capital also helps stabilise the naira by providing steady autonomous dollar liquidity to local contractor banks. Yet these financial gains depend entirely on the consortium reaching a binding final investment decision without fresh bureaucratic delays. Promises of investment mean nothing until construction cranes start swinging in fabrication docks.
Nigeria’s energy planners must now maintain regulatory discipline to prevent the project from stalling during the final contracting stage. Bureaucratic infighting among petroleum regulatory commissions has historically dragged out operating permits and inflated project development costs. The Nigerian Upstream Petroleum Regulatory Commission must fast-track environmental impact approvals and technical safety clearances to keep the construction schedule on track. State authorities must also ensure that national oil company equity calls are funded promptly to prevent cash-call arrears from slowing project partners. The global energy transition leaves Nigeria with a narrowing window of time to monetise its offshore hydrocarbon reserves before global oil demand peaks. Every year lost to regulatory red tape lowers the commercial value of these oil assets. Clear administrative pathways remain essential to turn signed papers into physical barrels.
The signing of the OML 118 addenda marks a welcome return of corporate confidence to Nigeria’s petroleum sector. If the consortium proceeds to a final investment decision on schedule, Bonga Southwest will anchor the next generation of Nigerian deepwater output. The project proves that competitive fiscal terms can revive dormant oil assets even in a tight global capital market. State authorities must now apply this same pragmatic commercial approach to unlock stalled deepwater projects across other offshore blocks. Unlocking idle reserves in fields like Zabazaba and Bonga North would cement Nigeria’s position as Africa’s premier offshore energy hub. The nation cannot afford to let vast wealth lie buried under deep waters while public treasuries borrow trillions for basic survival. Action at sea must match the bold rhetoric in Abuja.
