Shell Nigeria Exploration and Production Company (SNEPCo), a subsidiary of Shell Plc, on Monday confirmed plan to acquire TotalEnergies’ 12.5 % stake in deepwater Bonga Field.

Consequence upon this, an agreement has been signed by the two parties.

Shell confirmed the divestment in a statement on Monday, saying the transaction, when completed, will increase its interest in the OML 118 PSC from 55% to 67.5%.

The stake is in the OML 118 Production Sharing Contract (OML 118 PSC), an oil mining lease offshore Nigeria that includes the Bonga field.

SNEPCo is the operator under the OML 118 PSC. It currently produces from the Bonga field via the Bonga Floating Production Storage and Offloading (FPSO) vessel and announced the development of the Bonga North field in December 2024.

“Following our final investment decision on Bonga North last year, this acquisition brings another significant investment in Nigeria’s deep-water that contributes to sustained liquids production and growth in our Upstream portfolio,” said Peter Costello, Shell’s President, Upstream.

The transaction is subject to regulatory approvals and other closing conditions. The transaction is expected to be completed before the end of this year.

SNEPCo (55%) operates the Bonga field in partnership with Esso Exploration and Production Nigeria Ltd. (20%), Nigerian Agip Exploration Ltd. (12.5%), and TotalEnergies EP Nigeria Ltd. (12.5%), on behalf of the Nigerian National Petroleum Company Limited (NNPC).

After completion of the transaction, SNEPCo will hold a 67.5% stake, alongside Esso Exploration and Production Nigeria Ltd. (20%) and Nigerian Agip Exploration Ltd. (12.5%).

This targeted investment contributes towards growing Shell’s combined Integrated Gas and Upstream total production by 1% per year to 2030 and contributes towards sustaining our 1.4 million barrels per day of liquid production.

The Bonga field is a deep-water development located in OML 118, at water depths exceeding 1,000 meters. Production from Bonga began in 2005, with a capacity to produce 225,000 barrels of oil per day. The Bonga field produced its one-billionth barrel of crude oil in 2023.

In December 2024, Shell announced a final investment decision on Bonga North, a subsea tie-back to the Bonga FPSO. Bonga North currently has an estimated recoverable resource volume of more than 300 million barrels of oil equivalent and is expected to reach peak production of 110,000 barrels of oil a day, with first oil anticipated by the end of the decade.

The estimated peak production and recoverable resources mentioned above are 100% total gross figures. The recoverable resources are currently classified as 2P (proven and probable) under the Society of Petroleum Engineers’ Petroleum Resources Management System.
