Daily oil production in the Stabroek Block has increased to 900,000 barrels, ExxonMobil Guyana and its co-venturers have announced.

In a statement, ExxonMobil said the achievement comes just months after the successful startup of Guyana’s fourth offshore oil project at Yellowtail. The project has now achieved its initial annual average production capacity of 250,000 barrels of oil per day.

ExxonMobil Guyana President, Alistair Routledge, said the operators in the Stabroek Block continue to safely deliver industry-leading performance.

“Guyana’s story is one of continuous achievements because of the close collaboration with the Government of Guyana, our co-venturers, suppliers, contractors, and employees. Together, we are building a world-class energy sector that is delivering significant value for the people of Guyana,” Routledge said.

The Stabroek co-venturers have committed more than US$60 billion to develop seven projects on Guyana’s offshore Stabroek block including Uaru, Whiptail, and Hammerhead.

The Uaru and Whiptail projects, Guyana’s fifth and sixth projects, are each expected to produce approximately 250,000 bopd. The projects are expected to begin operations in 2026 and 2027, respectively, while the Hammerhead, the seventh project, is expected to add approximately 150,000 bopd when production begins in 2029.

Exxon said the eighth project, Longtail, is currently undergoing regulatory reviews. Once approved, ExxonMobil Guyana expects to have total production capacity of 1.7 million bopd from eight developments.
