Shell, via its subsidiary Shell Offshore, has finalised the sale of its 50% non-operated working stake in the Na Kika platform and related fields, as well as its 100% ownership of the Coulomb tieback in the Gulf of Mexico (GoM).
The transaction, announced in June 2026, has resulted in Shell receiving approximately $840m (£631.93m) in cash, following adjustments from the effective date of 1 July 2025 until the deal’s completion.

The assets have been acquired by a subsidiary of Talos Energy and an affiliate of Ridgewood Energy.
As part of the transaction, the buyers have taken on certain decommissioning obligations and are required to provide security for these commitments.
Shell will retain offtake rights from Na Kika and Coulomb through separate agreements arranged with the new owners.
The deal also allows Shell to earn upside-linked payments through 2027 without a set cap. This is in addition to overriding royalty interests on production from any additional Na Kika tiebacks, contingent upon specific conditions.
When the sale was signed, the total consideration was set at $1.7bn before usual adjustments and potential contingent payments.
During 2025, Shell’s share of production from these assets amounted to 37,000 barrels of oil equivalent per day.
According to Shell’s internal projections, neither Na Kika nor Coulomb are expected to make significant contributions to the company’s production portfolio by 2030.
The Na Kika semi-submersible platform has been in production since 2003, with the Coulomb tieback beginning output in 2005.
BP holds the remaining 50% operated interest in Na Kika.
At the end of 2025, Shell reported proved reserves of approximately 4.3 million barrels of oil equivalent (mboe) for Na Kika and 7.2mboe for Coulomb.
Shell maintains significant operations in the US, with activities and interests in every state.
According to the company, it is the largest deep-water operator and oil and gas producer in the GoM and ranks among the major buyers of US liquefied natural gas.
As of January 2026, Shell employed more than 11,000 people in the US, where it has been present for more than a century.
