Wedoany.com Report-Aug. 9, On August 8, 2025, ExxonMobil Guyana commenced operations at the Yellowtail development, its fourth offshore oil project in the Stabroek block, located off the coast of Guyana. The ONE GUYANA floating production, storage, and offloading (FPSO) vessel enhances Guyana’s oil production capacity, bringing the total to over 900,000 barrels per day, alongside the existing Destiny, Unity, and Prosperity FPSOs.

Dan Ammann, president of ExxonMobil Upstream Company, stated: “Yellowtail’s ahead-of-schedule startup is a significant milestone for ExxonMobil and the people of Guyana. With Guyanese making up more than 67% of the country’s oil-and-gas workforce and over 2,000 local businesses engaged, this project reflects our deepening roots in the country and our shared commitment to long-term, inclusive growth.”

The ONE GUYANA FPSO, the largest in the Stabroek block, has an initial production capacity of 250,000 barrels per day and can store up to two million barrels of crude oil, which will be marketed as Golden Arrowhead crude. This development strengthens Guyana’s position in the global energy market.

ExxonMobil Guyana projects a total production capacity of 1.7 million oil-equivalent barrels per day by 2030, with plans for eight developments in the Stabroek block. The company has successfully launched four major offshore projects in the past five years, all completed ahead of schedule and within budget, while also planning four additional projects by the decade’s end.

ExxonMobil Guyana Limited operates the Stabroek block with a 45% stake, while Hess Guyana Exploration Ltd. holds 30%, and CNOOC Petroleum Guyana Limited owns 25%. The project emphasizes local workforce participation and business engagement, fostering sustainable economic growth in Guyana.
