Shell announces offshore Dover field startup in the GoM

Shell Offshore Inc. has reported the start of production at Dover, its second subsea tieback connecting new wells to the Shell-operated Appomattox production hub in the US Gulf of Mexico.

The Dover development is a subsea tieback to the Appomattox asset with up to two production wells produced through a 17.5-mile flowline and riser.

First discovered in 2018, Shell says that the Dover field brings an estimated peak production of 20,000 barrels of oil equivalent (boe) per day.

The Dover field is located within Mississippi Canyon, approximately 170 miles offshore southeast of New Orleans, Louisiana, in about 7,500 ft of water.

Current estimates are that Dover will contain 44.5 MMboe recoverable resources. The estimate of resource volumes is currently classified as 2P under the Society of Petroleum Engineers' Resource Classification System.

“Shell continues to unlock more value from the prolific basins in our portfolio,” said Colette Hirstius, Shell's executive vice president, Gulf of America. “Dover is another example of the ways in which we maximize the production of our deepwater 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.”
