BP PLC announced on 30th July 2026 that it has increased the production capacity of the Atlantis deepwater field on the United States side of the Gulf of America by 10,000 barrels of oil equivalent a day (boed), marking another step in its ongoing Atlantis expansion efforts.
In a press release, BP stated, “The expansion project adds two new subsea water injection wells to help increase the pressure of targeted reservoirs, unlocking additional barrels and extending the producing life of one of BP’s flagship U.S. offshore assets”.
The company also confirmed that the project reached completion ahead of schedule while remaining under budget. Commenting on the development, Andy Krieger, BP senior vice president for the Gulf of America and Canada, said, “Atlantis has been one of the anchors of our Gulf business for nearly two decades, and this expansion proves there is still more value to be generated”.
BP noted that the earlier Atlantis Drill Center 1 Expansion project, completed in late 2025, had already contributed an additional 15,000 boed of production capacity. Prior to these two projects, the Atlantis field had a declared peak production capacity of 200,000 barrels of oil and 180 million cubic feet of gas per day. The Atlantis expansion continues to build on the field’s established production base.
BP Advances Wider Gulf of America Offshore Development Portfolio
BP operates the Atlantis field, located around 150 miles south of New Orleans, with a 56 percent interest, while Australia’s Woodside Energy Group Ltd owns the remaining 44 percent stake.
Last year, BP sanctioned the Tiber-Guadalupe oil project, which includes a new production platform designed with a capacity of 80,000 barrels per day (bpd). The company plans to bring the project onstream in 2030, when the Tiber platform is expected to become BP’s seventh operated Gulf production platform. BP said on 29th September 2025, that the Tiber and Guadalupe developments, together with the under-construction Kaskida project, are expected to lift the company’s Gulf production to more than 400,000 boed. The initial phase of Tiber and Guadalupe is estimated to contain around 350 million boe of recoverable resources and involves an investment of $5 billion, including six wells in Tiber and a two-well tieback in Guadalupe.
BP also announced a final investment decision on Kaskida on 30th July 2024. The project has a production capacity of 80,000 bpd and is planned to begin operations in 2029 through a six-well development. According to BP, the field contains an estimated 275 MMboe recoverable resources. Kaskida, Guadalupe and Tiber are all situated in the Keathley Canyon area off the coast of New Orleans.
Alongside the Atlantis expansion, BP continues to operate four producing platforms in the Gulf of America—Argos, Mad Dog, Na Kika and Thunder Horse. On 4th August 2025, the company announced the start of production at the Argos Southwest Extension project, which added 20,000 bpd of capacity to the Argos platform that entered production in 2023.
