US Gulf of Mexico Faces Production Decline Despite Record Output

Beacon Offshore Vice President Joseph Leimkuhler warned at the 2026 Offshore Technology Conference that energy production from the US Gulf is poised to decline in the coming years, despite record-high crude oil output in 2025. He highlighted that the number of operators and service providers active in the region hit "an all-time low" last year, creating an ironic contrast with the reported production peak. Leimkuhler stated, "I fully expect US offshore production to decline in the next couple of years," emphasizing the need for more operators and more wells to be drilled.

Near-Term Challenges and Future Projects

While acknowledging new mega-projects like Shell's Sparta and BP's Kaskida could eventually change the equation, Leimkuhler noted these developments will take years to enter production. BP targets a 2029 online date for Kaskida, and Shell, which made a final investment decision on Sparta in 2023, predicts first production in 2028. This timeline sets up the region for declining rates in the near term.

Lessons from the Shenandoah Project

Leimkuhler provided an update on the groundbreaking Shenandoah US Gulf project, which is only the second offshore development in the region requiring certification of subsea equipment capable of operating at 20,000 pounds per square inch (20K technology). The project faced significant technical challenges, causing several companies to drop out before LLOG and Beacon took over the lease. Shenandoah achieved first production in July 2025 and is now producing 120,000 barrels per day of oil, with an expansion underway. The partners are drilling two additional wells at the Monument site to be tied back to the production platform, and plans include developing the subsea Shenandoah South site to add more wells.

Timeline and Technical Hurdles

Leimkuhler explained that Shenandoah was a challenge because the project was conceived before the necessary technology existed. The timeline shows 22 years passed from the offshore lease award to first production, with hydrocarbons first discovered at the site 17 years ago. In April, the US Department of the Interior reported that oil production from the US Gulf hit a record high in 2025, with producers delivering a combined 714 million barrels for the full year, described as "the highest annual output on record."
