Shell joining Equinor’s deepwater Gulf of Mexico project as operator

Norwegian state-owned oil and gas giant Equinor has inked a deal to transfer a majority stake and operatorship of its field in the Gulf of Mexico to the UK-headquartered oil major, Shell.


Equinor revealed on Wednesday that it had agreed to sell 51 per cent of its interest in the North Platte deepwater development project in the U.S. Gulf of Mexico to Shell. No financial details have been revealed so far.

After the deal is completed, Equinor will retain 49 per cent interest in this project, while Shell will become the new operator of the field. In lieu of this change, the two energy giants have agreed to rename the North Platte development to the Sparta development.

Commenting on this deal, Chris Golden, Equinor’s Senior Vice President, U.S. Upstream, Exploration and Production International, remarked: “Equinor has a long-term view of Sparta as a high-quality project with a clear strategic fit for the company. Sparta will strengthen our position in the Gulf of Mexico as well as our overall role as a reliable energy supplier to the U.S.”

The North Platte field was discovered in 2012 by Cobalt International Energy, which at the time held 60 per cent interest, while Total (now TotalEnergies) held the remaining 40 per cent. In March 2018, Equinor joined as a partner by acquiring Cobalt’s 40 per cent interest, while TotalEnergies became the operator of this project with 60 per cent interest, following the acquisition of a 20 per cent stake for $339 million during Cobalt’s bankruptcy auction sale

Moreover, the North Platte field (now renamed Sparta) straddles four blocks of the Garden Banks area – GB blocks 915, 916, 958 and 959 – 275 kilometres or 171 miles off the coast of Louisiana in approximately 1,300 meters or 4265 feet of water depth.

Back in December 2019, TotalEnergies started the front-end engineering and design (FEED) for the North Platte discovery and Worley was working on the FEED for the development under a contract awarded in early 2020. The final investment decision was expected in 2021, however, TotalEnergies withdrew from the project in February 2022 releasing all its equity to Equinor.

While announcing the deal with Shell, Equinor explained that the FEED had matured for the project. The company intends to work closely with Shell to review the work that has been completed and to update the development plan. This transaction is subject to customary conditions and authority approval.

“This is a development opportunity that is expected to add significant value with lower carbon emissions intensity. We are pleased to welcome Shell and look forward to sharing our experience and technology to move this valuable project forward,” added Golden.
