Oil production offshore Guyana averaged 685,000 barrels per day (b/d) in August, up from 664,000 b/d in July, driven mainly by the start-up of the Yellowtail project. The new development, which began production on August 8, averaged 75,000 b/d in its first weeks and is expected to continue ramping up toward its design capacity of 250,000 b/d by the final quarter of the year.
Among the other projects, Liza 1 averaged 131,000 b/d in August, a gradual decline from its plateau of 160,000 b/d, observed last year. Liza 2 averaged 233,000 b/d, down about 31,000 b/d from July, although this project can produce up to 270,000 b/d. Meanwhile, Payara hit 263,000 b/d, reflecting strong performance near its 265,000 apparent limit.

Exports from Yellowtail were limited in August, with a single million-barrel cargo shipped to the Netherlands. Additional cargoes followed in September as the field’s output slowly increased.
On a broader scale, year-to-date production averaged 648,000 b/d in the first eight months of 2025, up from 597,000 b/d in the same period last year. Installed capacity across Guyana’s four producing projects now exceeds 900,000 b/d. The government projects that combined output will reach 786,000 b/d in the final quarter.
All of Guyana’s current oil production comes from the ExxonMobil-operated developments in the Stabroek Block, with partners Hess (acquired by Chevron) and CNOOC holding stakes in the projects.
