Shell Expands Gulf of America leadership position with Dover development

HOUSTON, April 8, 2025 /PRNewswire/ -- Shell Offshore Inc. (Shell), a subsidiary of Shell plc, today announced the start of production at Dover, the second subsea tieback connecting new wells to the existing infrastructure of the Shell-operated Appomattox production hub in the Gulf of America. Dover brings an estimated peak production of 20,000 barrels of oil equivalent per day.

"Shell continues to unlock more value from the prolific basins in our portfolio," said Colette Hirstius, Executive Vice President, Gulf of America. "Dover is another example of the ways in which we maximize the production of our deep-water hubs as we deliver on our strategy to create more value with less emissions. The high-margin, lower-carbon barrels from the Gulf of America are essential to our energy system, both now and in the future."

Shell is the leading deep-water operator in the Gulf of America, where our production has among the lowest greenhouse gas intensity in the world for producing oil.

Notes to editors

• Shell discovered Dover in 2018.
• Dover is located within Mississippi Canyon, approximately 170 miles offshore southeast of New Orleans, Louisiana in about 7,500 feet of water.
• Shell has 100% working interest (WI) in Dover.
• The Dover development is a subsea tieback to the Shell-operated Appomattox asset with up to two production wells produced through a 17.5-mile flowline and riser.
• Shell operates Appomattox with 79% WI, with INEOS Energy Petroleum Offshore USA Inc. controlling the remaining 21%. Dover is expected to produce up to 20,000 barrels of oil equivalent per day at peak rates.
• Current estimates are that Dover will contain 44.5 million barrels of oil equivalent recoverable resources, adding stable, secure energy resources that the United States and the world need today and in the future. The estimate of resource volumes is currently classified as 2P under the Society of Petroleum Engineers' Resource Classification System.
• Rydberg, the first subsea tieback to Appomattox, came online in February 2024.
• The reference to our Gulf of America production being among the lowest GHG intensity in the world is a comparison among other IOGP oil and gas producing members.
• The estimated peak production and current estimated recoverable resources presented above are 100% total gross figures.

Shell's Net Carbon Intensity

Also, in this press release we may refer to Shell's "Net Carbon Intensity" (NCI), which includes Shell's carbon emissions from the production of our energy products, our suppliers' carbon emissions in supplying energy for that production and our customers' carbon emissions associated with their use of the energy products we sell. Shell's NCI also includes the emissions associated with the production and use of energy products produced by others which Shell purchases for resale. Shell only controls its own emissions. The use of the terms Shell's "Net Carbon Intensity" or NCI are for convenience only and not intended to suggest these emissions are those of Shell plc or its subsidiaries.

Shell's net-zero emissions target

Shell's operating plan, outlook and budgets are forecasted for a ten-year period and are updated every year. They reflect the current economic environment and what we can reasonably expect to see over the next ten years. Accordingly, they reflect our Scope 1, Scope 2 and NCI targets over the next ten years. However, Shell's operating plans cannot reflect our 2050 net-zero emissions target, as this target is currently outside our planning period. In the future, as society moves towards net-zero emissions, we expect Shell's operating plans to reflect this movement. However, if society is not net zero in 2050, as of today, there would be significant risk that Shell may not meet this target.

Forward-looking non-GAAP measures

This press release may contain certain forward-looking non-GAAP measures such as cash capital expenditure and divestments. We are unable to provide a reconciliation of these forward-looking non-GAAP measures to the most comparable GAAP financial measures because certain information needed to reconcile those non-GAAP measures to the most comparable GAAP financial measures is dependent on future events some of which are outside the control of Shell, such as oil and gas prices, interest rates and exchange rates. Moreover, estimating such GAAP measures with the required precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable effort. Non-GAAP measures in respect of future periods which cannot be reconciled to the most comparable GAAP financial measure are calculated in a manner which is consistent with the accounting policies applied in Shell plc's consolidated financial statements.
