THE BONGA SOUTH-WEST APARO PROJECT

After more than two decades beneath the deep waters of Nigeria's offshore Niger Delta, the Bonga South-West Aparo project is moving closer to reality. Its potential lifetime investment, estimated at between $15 billion and $21 billion, could make it one of the country's defining tests for restoring confidence in large-scale energy projects.

The project has survived changes in government, shifting fiscal policies, prolonged negotiations and commercial disputes. It has also advanced during a period when the global energy transition has made investment decisions on large oil developments increasingly difficult.

Momentum returned in August 2026, when NNPC Limited and contractor partners signed addenda to the Oil Mining Lease 118 Production Sharing Contract and the Dispute Settlement Agreement. The partners are Shell Nigeria Exploration and Production Company, Esso Exploration and Production Nigeria (Deepwater), and Nigerian Agip Exploration.

The agreements give effect to fiscal and commercial terms approved by the Federal Government. They are intended to create the conditions needed for the partners to proceed toward a Final Investment Decision, or FID, on the long-delayed development.

The latest step followed the government's approval of the Deep Offshore Oil and Gas Projects Incentives (Tax Remission) Order, 2026. The policy aims to improve the competitiveness of Nigeria's deepwater investment environment, which is crucial for projects requiring large amounts of capital and long development timelines.

For Nigeria, the significance extends beyond a single oilfield. At the upper end of current projections, the project could attract $21 billion in investment at a time when global capital is increasingly cautious about long-cycle fossil-fuel developments. The article presents that figure as a major measure of whether Nigeria has rebuilt the conditions needed to attract substantial upstream investment.
