Fossil Energy – Expansion Project
BP has put into production mode an expansion project in the Gulf of Mexico.

It is its seventh major upstream project to start this year, and the fifth to come online ahead of schedule.
Two months after bringing its Murlach subsea tie-back development to the existing Eastern Trough Area Project (ETAP) central processing facility (CPF) on stream in the UK sector of the North Sea as its sixth major project in 2025, BP has delivered first oil two months ahead of plan from the two-well Atlantis Drill Center 1 expansion project in the Gulf of America, which is its seventh major project start-up.
This subsea tie-back to the existing Atlantis platform will add gross peak production of around 15,000 barrels of oil equivalent per day (boe/d). Atlantis, one of BP’s longest-running platforms in the Gulf of America, has a gross production capacity of up to 200,000 barrels of oil per day. The firm is Atlantis’ operator with a 56% working interest, and the co-owner is Woodside Energy with the remaining 44% working interest.
The Atlantis Drill Center 1 expansion, which connects new wells to existing offshore production facilities through pipelines, extends the footprint of the Atlantis field discovered in 1998. The company delivered the tie-back by utilizing existing subsea inventory, drilling and completing wells more efficiently, and streamlining offshore execution planning.
