Securing transaction of approximately US$840mn, Shell Offshore Inc has closed the sale of its non-operated 50% working interest in the Na Kika platform and associated fields, alongside its fully owned Coulomb subsea tieback in the Gulf of Mexico.

The offshore assets were acquired jointly by a subsidiary of Talos Energy and an affiliate of Ridgewood Energy.

Shell retains rights to uncapped upside-linked payments running through 2027, as well as overriding royalty interests (ORRI) on future production derived from new tiebacks to the Na Kika host facility.

The acquiring parties have agreed to assume defined decommissioning obligations, backed by financial security guarantees.

The divestment falls in line with Shell’s strategic focus on streamlining its upstream portfolio for lower-cost, resilient deep-water developments. After studying internal modeling, the company concluded that neither asset would contribute significantly to its long-term production profile heading toward 2030.

Operating since 2003, Shell held the semi-submersible Na Kika facility with bp, which serves as the operator and retains its 50% stake. At year-end 2025, Shell’s proved reserves stood at 4.3 million barrels of oil equivalent (boe). The Coulomb Tieback, on the other hand, has been integrated into the regional infrastructure in 2005. The asset held 7.2 million boe in proved reserves for Shell at the end of 2025.

Shell’s net entitlement share across both assets averaged approximately 37,000 boe per day during 2025.

Despite the sale, Shell maintains a prominent presence in high-margin deep-water basins, remaining the premier producer and operator in the Gulf of Mexico alongside extensive holdings in Brazil.

The United States remains one of Shell’s largest global markets, spanning major deep-water operational hubs, a nationwide retail network of nearly 12,000 branded stations, extensive LNG trading operations, and a domestic workforce exceeding 11,000 employees.
