BP and ExxonMobil have reached a final investment decision for a subsea pump project linked to the Thunder Horse offshore platform in the U.S. Gulf of Mexico.

The development is intended to increase production from BP’s largest oil and gas production platform. Based on current plans, the project is expected to contribute approximately 15,000 barrels of oil equivalent per day in peak gross annual average production.

Under the current schedule, first oil is targeted for 2028.

The subsea pump project is being introduced to support and strengthen production at Thunder Horse. The development is also viewed as the first use of an approach that BP expects could be expanded to future projects, including Kaskida and Tiber.

Project Manager Joseph Scattergood said the initiative reflects close cooperation with ExxonMobil, adding that safety, collaboration, quality and capital productivity remain key elements for successful project delivery.
