Shell Divests Na Kika Gulf Deepwater Stake to Talos Energy and Ridgewood for $1.7 Billion

Shell Offshore Inc. has agreed to sell its 50% non-operated working interest in the Na Kika semi-submersible production platform and associated deepwater fields, plus its wholly owned Coulomb subsea tieback, to subsidiaries of Talos Energy and Ridgewood Energy. The purchase price is $1.7 billion, subject to customary adjustments and contingent payments that include uncapped upside-linked compensation through 2027. BP, which operates Na Kika and holds the remaining 50% working interest, has a 30-day right of first refusal to acquire Shell's stake at the same terms.

Na Kika: 23 Years in the Mississippi Canyon

Na Kika sits in the Mississippi Canyon approximately 140 miles southeast of New Orleans, in water 6,340 feet deep. When it began producing in 2003, the facility was the world's deepest permanently moored semi-submersible production platform. The field is named after the Polynesian deity of the octopus, a reference to how its subsea tiebacks fan out from a central hull to connect multiple small fields. Shell's 50% entitlement production from the platform and associated fields averaged approximately 37,000 barrels of oil equivalent per day in 2025. Shell also holds 100% of the Coulomb tieback, which entered production in 2005.

Shell stated in the press release that it expects Na Kika and Coulomb will not be meaningful contributors to production by 2030. Together, the two assets reported combined proved reserves of 11.5 million barrels of oil equivalent at year-end 2025, split between 4.3 million boe for Na Kika and 7.2 million boe for Coulomb. The Coulomb tieback, entirely owned by Shell, accounts for nearly two-thirds of the combined proved inventory despite being a single subsea installation.

The Valuation Math: $148 Per Proved Barrel at Current Brent

At $1.7 billion for 11.5 million boe in proved reserves, the implied price is approximately $148 per barrel of oil equivalent. Brent crude futures were trading at $71.82 per barrel in early Tuesday morning trading on ICE, per OilPrice.com, down from Monday's ICE settlement of $73.44. Buyers are paying roughly 2.1 times today's Brent benchmark per barrel of proved reserves. That premium reflects future tieback optionality: Shell retains only an overriding royalty interest on future tiebacks, meaning Talos and Ridgewood capture the full economic upside from any new fields connected to the platform after closing.

Shell's entitlement production of 37,000 boe/day translates to a flowing-barrel acquisition cost of approximately $46,000 per daily barrel. WTI crude futures were trading at $68.75 per barrel in early July 1 trading on CME, per OilPrice.com. At that WTI level, Shell's share of production generates roughly $2.5 million per day in gross commodity revenue before royalties and lifting costs.

BP as Operator Holds a 30-Day Wild Card

Under the Na Kika joint operating agreement, BP has 30 days from the announcement date to elect whether to acquire Shell's interest at the same price and terms offered to Talos and Ridgewood. BP has operated Na Kika since first oil in 2003 and holds the complementary 50% working interest. An exercise of that right would consolidate 100% operated control of the world's second-deepest production semi-submersible and position BP as sole decision-maker on future Mississippi Canyon tiebacks. BP has not publicly stated its intentions regarding the preferential right.

Shell Retains Operated Gulf Hubs; Talos Adds Scale

Na Kika was Shell's only non-operated platform in the Gulf of America. Shell continues to operate the Mars, Ursa, and Olympus semi-submersible hubs in the same basin. Upstream President Peter Costello said the company is actively shaping its portfolio to ensure the upstream business remains resilient and competitive. Shell Trading US Company retains offtake rights under negotiated commercial agreements with the buyers, maintaining its marketing presence on the production stream after the ownership transfer.

Talos Energy (NYSE: TALO) was founded in 2012 with backing from Apollo Global Management and Riverstone Holdings and went public in 2018 following a merger with Stone Energy Corporation. The company focuses exclusively on deepwater and shelf operations in the Gulf of America. Ridgewood Energy, a private equity-backed Gulf deepwater specialist, is the other buyer. Neither company has disclosed its individual portion of the $1.7 billion purchase price.

Pricing Context: Oil Enters H2 2026 Under Pressure

Brent shed approximately 2.2% overnight from Monday's ICE settlement, entering H2 2026 under pressure from OPEC+ production ramp-ups and normalized Hormuz traffic. As Oil Authority reported on the Iran ceasefire settlement, Goldman Sachs projected Brent at $82 per barrel in Q3 2026, a target the market has moved further from in recent sessions. Shell's decision to divest Na Kika at roughly $148 per proved barrel, with WTI at $68.75, suggests management viewed the aging non-operated asset as more valuable in a pure-play buyer's portfolio at current prices.
