Shell Offshore Divests Coulomb Field and Na Kika Interests to Talos Energy and Ridgewood for $1.7 Billion

Shell Offshore Inc. is the US subsidiary of Shell plc, one of the world's largest integrated oil and gas companies. On June 30, it agreed to sell its deepwater Gulf of America oil interests to Talos Energy and Ridgewood Energy for a combined $1.7 billion. The assets include a 50% stake in the Coulomb field and Shell's existing interests in the BP-operated Na Kika platform, both located in Mississippi Canyon on the outer continental shelf.

Deal Structure: Two Buyers, Split Assets

Under the purchase agreement dated June 30, 2026, Talos Energy's subsidiary Talos Ocho Energy LLC acquires a 50% working interest and full operatorship in the Coulomb field. Talos and Ridgewood Energy, through affiliate RE Fund V Holdco II Infrastructure LLC, together acquire a 25% non-operated interest in the Na Kika platform and four associated fields: Kepler, Ariel, Fourier, and Herschel. Each buyer holds an undivided 50% interest in all acquired assets, per Talos's SEC filing. Talos's gross purchase price is approximately $850 million, with a net price of $450 million to $500 million after adjusting for cash flows generated since the July 1, 2025 effective date.

BP Holds a 30-Day Preferential Right on Na Kika

BP, which operates the Na Kika platform, holds a 30-day preferential purchase right on the interests Talos and Ridgewood are acquiring. If BP exercises that right, the acquisition narrows to Coulomb only, with the Na Kika portion removed from the $1.7 billion total. BP has not publicly stated whether it will exercise the right. The preferential period began upon notification to BP at or near the June 30 signing date.

Assets Produce 16,000 Boe/d at 77% Oil

The combined Coulomb and Na Kika assets produced approximately 16,000 barrels of oil equivalent per day in Q1 2026, with crude oil making up roughly 77% of that output, per Talos's SEC disclosure. Proved reserves stand at approximately 23 million barrels of oil equivalent, with another 10 million MMBoe classified as probable. In 2025, these interests generated $371 million in revenues and $335 million above direct operating costs, according to financial statements in Talos's July 1 SEC filing. Q1 2026 results tracked at an annualized revenue pace of $358 million, with $328 million above direct operating costs.

$73.90 Per Proved Barrel: How the Valuation Stacks Up

At the $1.7 billion combined deal price and 23 million MMBoe of proved reserves, Shell is monetizing its deepwater position at approximately $73.90 per barrel of oil equivalent in the ground. WTI crude futures traded at $68.58 per barrel on Wednesday, per oilprice.com near-real-time data, down $0.92 or 1.32% from Tuesday's close. Talos's $850 million gross investment against annualized Q1 2026 cash flow above direct operating costs of approximately $328 million implies a 38.6% annual operating cash yield before G&A and capital expenditures. Those offshore margins carry a meaningful premium over many shale alternatives at current WTI levels.

Shell's Broader Portfolio Pivot: Exiting Oil, Entering Montney Gas

This divestiture runs alongside Shell's concurrent bid to acquire ARC Resources for CAD $22 billion, as previously reported by Oil Authority. That deal would give Shell operatorship of the Groundbirch gas complex in the Montney formation, feeding LNG Canada's export terminal at Kitimat. Together, the two transactions reveal a deliberate rebalancing: Shell is shedding mature deepwater Gulf of America oil while acquiring a large-scale Canadian gas position tied to Pacific LNG export. The Montney acquisition is pending an ARC Resources shareholder vote; the Gulf of America asset sale is expected to close by end of 2026, subject to antitrust clearance and BP's preferential rights period.

Financing and Timeline

Talos funded its portion through a combination of cash on hand and expanded credit facilities. The company secured $150 million in new incremental commitments, raising its borrowing base from $700 million to $850 million, per its June 30 SEC filing. A $42.5 million escrow deposit was placed at signing. Hart-Scott-Rodino antitrust clearance is required before the deal can close, alongside expiration of BP's preferential purchase right period.

Executive Comments

Talos CEO Paul Goodfellow, in documents filed with the U.S. Securities and Exchange Commission on June 30, described the transaction as "highly accretive" and said it "materially enhances free cash flow." Goodfellow added that the acquired assets provide "infrastructure-led exploration opportunities" given the deepwater Mississippi Canyon infrastructure already in place. CFO Zach Dailey noted the deal maintains "balance sheet strength and financial flexibility," per the same SEC filing. Neither executive issued a standalone press release as of Wednesday afternoon.
