Shell Offshore, a subsidiary of Shell plc, this week 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.

Key facts

• 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.

• 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.
