Shell Plc and Ineos Energy are moving forward with oil and gas exploration projects close to Shell’s Appomattox platform in the Gulf of Mexico, The Times reported. That includes ongoing work at the Fort Sumter discovery and plans for a potential new exploration well, which could be drilled before the decade wraps up. The effort comes as Shell looks to sharpen its U.S. offshore strategy, landing just ahead of its first-quarter earnings release.
Timing is a key issue here. Shell CEO Wael Sawan faces mounting demands to clarify how the company—the biggest in Europe by oil and gas market value—intends to replenish its shrinking reserves without compromising hefty cash returns. Back in February, Reuters flagged that Shell’s reserve life had slipped below eight years, well short of the more than 12 years reported for Exxon Mobil and TotalEnergies.
The Gulf announcement comes just a week after Shell unveiled its plan to acquire Canada’s ARC Resources, picking up 370,000 barrels of oil equivalent a day in the process. That’s “boe”—a standard metric bundling oil, gas, and liquids production into a single figure. With ARC folded in, Shell expects its annual production growth rate to rise to 4% through 2030. Shell
The Times says the Ineos collaboration breaks down into three main pieces: work on Fort Sumter, scouting for a potential second exploration well nearby, and chasing broader prospects around Appomattox. Fort Sumter itself carries more than 125 million barrels of oil equivalent in recoverable resources, according to Shell’s 2016 discovery announcement.
Ineos stepped up its role at Appomattox after wrapping up its acquisition of CNOOC’s U.S. Gulf assets in April 2025. The move handed Ineos stakes in both Appomattox and Stampede, pushing its worldwide production past 90,000 boe per day, according to the company.
“The USA is a very attractive place for INEOS Energy to invest,” Ineos Energy CEO David Bucknall said at the announcement of the CNOOC deal. According to Bucknall, Ineos’ energy capital spending stateside has topped $3 billion — describing it as “a strong platform for future growth.” INEOS
Shell holds a 79% working interest in Appomattox, with Ineos owning the other 21%, according to Shell’s April 2025 statement on the Dover subsea tieback. Dover—tied back to Appomattox—is targeting peak output of up to 20,000 boe per day. Shell’s current figure for recoverable resources at Dover sits at 44.5 million boe.
Shell has relied on Appomattox as a central hub for nearby fields, sidestepping the higher costs of building separate platforms. This year, the company brought Rydberg online—a fresh tieback to Appomattox—with an expected peak of 16,000 boe a day. “We will continue to mature the best opportunities for growth in the Gulf of Mexico,” said Rich Howe, Shell’s deep-water EVP, at the time.

Shell’s North American gas ambitions now get a major Canadian boost. Sawan described ARC as turning Canada into a “heartland” for the company, a move he says will back up Shell’s supply for “decades to come.” ARC’s assets are concentrated in the Montney shale across British Columbia and Alberta. The purchase is directly linked to Shell’s LNG push; the company wants more feedstock for its liquefied natural gas business—natural gas cooled to a liquid state for shipping by sea. ARC Resources
With the London Stock Exchange shuttered for the early May bank holiday on Monday, markets didn’t get any new signals out of the city. Shell’s on deck with its first-quarter earnings and interim dividend update, both scheduled for release at 07:00 BST this Thursday, May 7, per the company’s financial calendar.
Still, there’s plenty that could trip up the timeline. Gulf ventures hinge on drilling outcomes, costs staying in check, and whether final investment calls go their way. Over on the ARC front, shareholders, courts and regulators in both Canada and the U.S. all have to sign off before anything closes. ARC has pegged the transaction to wrap up in the back half of 2026, assuming all those hurdles are cleared.
