BP starts up Atlantis major facility expansion project in US Gulf

BP has started up its Atlantis Major Facility Expansion project in the US Gulf of America, adding two new subsea water injection wells to one of the company's longest-running deepwater assets. 

Atlantis is located about 150 miles south of New Orleans and has been in production for nearly 20 years, since its discovery in 1998. According to BP, the expansion project increases pressure at targeted reservoirs, unlocking additional barrels and extending the producing life of the field. The project also adds new subsea trees and new water injection pumps on the platform's topsides, and enables future water injection capability at Atlantis, which operates in 7,074 feet of water. 

BP said the project was delivered ahead of schedule and under budget. It adds approximately 10,000 barrels of oil equivalent per day (boe/d) of gross peak annualized average production, with around 5,000 boe/d net to BP. 

"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," said Andy Krieger, BP's senior vice president for the Gulf of America and Canada. "We're extending the life of a great asset while supporting jobs and investment in the region — all while making the most of infrastructure that's already in place."  

BP is the operator of Atlantis with a 56% working interest, while co-owner Woodside Energy holds the remaining 44%. Atlantis is one of five production platforms BP operates in the deepwater Gulf of America, alongside Argos, Mad Dog, Na Kika and Thunder Horse. 

The start-up follows BP's Atlantis Drill Center 1 expansion, which delivered first oil two months ahead of schedule at the end of 2025 as the company's seventh major project of that year. BP has also recently sanctioned two new production platforms, Kaskida and Tiber, which together are expected to add 160,000 barrels per day of new oil production capacity in the US offshore region by the end of 2030, as part of the company's plan to deliver ten major project start-ups globally by 2027.
