Shell Offshore, a subsidiary of Shell, has commenced production at Dover, a subsea tieback project linked to the Appomattox production hub in the Gulf of Mexico.
The Dover development is expected to reach peak production of 20,000 barrels of oil equivalent per day (boepd), strengthening Shell’s leadership in deep-water operations.
Discovered in 2018, Dover is situated within the Mississippi Canyon, approximately 170 miles (273.5km) south-east of New Orleans, Louisiana, in water depths of around 7,500 feet.
Shell holds a 100% working interest in Dover, which connects to the Appomattox asset through a 17.5-mile flowline and riser.
Shell operates Appomattox with a 79% working interest, while INEOS Energy Petroleum Offshore USA holds the remaining 21%.
Shell executive vice-president Gulf of America Colette Hirstius said: “Shell continues to unlock more value from the prolific basins in our portfolio.
“Dover is another example of the ways in which we maximise 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.”
The Dover development is expected to contribute 44.5 million barrels of oil equivalent in recoverable resources, classified as 2P (proven and probable) under the Society of Petroleum Engineers’ Resource Classification System.
Shell highlights that its Gulf of Mexico production boasts one of the lowest greenhouse gas intensities worldwide among oil-producing members of the International Association of Oil & Gas Producers.
In a related development, Shell Brasil has reached a final investment decision on the Gato do Mato project in Brazil’s pre-salt Santos Basin.
This deep-water project involves a consortium, with Shell holding a 50% stake, alongside Ecopetrol and TotalEnergies.
The project will feature an floating production storage and offloading vessel designed to produce up to 120,000 barrels of oil per day.
