ExxonMobil Guyana Limited announced that it has secured Front‑End Engineering and Design (FEED) contracts for the Floating Production, Storage and Offloading (FPSO) vessel that will serve the Longtail development in Guyana. The award is a critical step toward the final investment decision and eventual production of the project.

The Longtail project is expected to produce up to 250,000 barrels per day of liquids and handle more than 1 billion cubic feet per day of gas, marking ExxonMobil’s first major foray into non‑associated gas development in the region. The project is estimated to cost roughly US$13 billion, with a final investment decision targeted for the end of 2026, production slated to begin in 2030, and an anticipated operating life of about 30 years.

This contract underscores ExxonMobil’s continued focus on Guyana’s high‑return offshore assets. The Stabroek Block, where Longtail is located, is estimated to hold nearly 9 billion oil‑equivalent barrels, and the award moves the project closer to a definitive investment, reinforcing the company’s strategic position in the region.

SBM Offshore, the design and construction partner, will build the FPSO using its Fast4Ward program and a ninth new‑build Multi‑Purpose Floater hull. This marks SBM’s sixth FPSO award from ExxonMobil Guyana, highlighting a strong and ongoing partnership in Guyana’s offshore developments.

Alistair Routledge, President of ExxonMobil Guyana, said the Longtail project would be a premium benchmark for next‑generation deepwater resource management, emphasizing reinjection, efficiency and longevity. He also noted that if gas is available and a market exists, the project could feed gas into that market.
