Guyana is approaching oil production of one million barrels per day (b/d), less than seven years after the country produced its first commercial crude from the ExxonMobil-operated Stabroek Block.
Production from four offshore projects averaged 903,000 b/d in April 2026, according to government data reviewed by OilNOW. The Uaru project, expected to begin producing before the end of this year, is positioned to carry national output beyond the one-million-b/d threshold.
The milestone will be supported by the Errea Wittu floating production, storage and offloading vessel. The FPSO is designed to produce approximately 250,000 b/d.
Uaru will become Guyana’s fifth producing development. It follows Liza 1, Liza 2, Payara, and Yellowtail, which brought the country from no oil production in 2019 to more than 900,000 b/d by early 2026.
The journey began on December 20, 2019, when the Liza Destiny FPSO achieved first oil at the Liza 1 development. The start-up came approximately four and a half years after ExxonMobil announced the Liza-1 discovery in May 2015.
Liza Destiny was initially designed to produce 120,000 b/d. Optimization work later allowed the vessel to operate above its original nameplate capacity. The project established the production infrastructure and operating model that would be used for subsequent developments in the Stabroek Block.
Guyana’s second project, Liza 2, began production in February 2022 through the Liza Unity FPSO. The vessel was originally designed for 220,000 b/d, but its optimized production capacity has since increased to approximately 270,000 b/d.

Payara became the third development to enter production when the Prosperity FPSO started operations in November 2023. The project reached its initial production target of 220,000 b/d in January 2024, three months ahead of schedule.
Those three projects were producing approximately 650,000 b/d before the start-up of Yellowtail in August 2025. Yellowtail added the ONE GUYANA FPSO, the fourth production vessel deployed offshore the country.
First oil was achieved on August 8, 2025, four months ahead of schedule. The development reached its initial target rate of 250,000 b/d in November, helping total production in the Stabroek Block reach 900,000 b/d.
Output continued to increase after Yellowtail’s ramp-up. Production averaged approximately 915,000 b/d in January 2026 and reached a record 918,000 b/d in February.
Uaru is expected to provide the next major increase. The government approved the US$12.7 billion project in April 2023. It targets more than 800 million barrels of recoverable oil from the Uaru, Mako, and Snoek fields.
The development comprises up to 10 drill centers and 44 production and injection wells. Errea Wittu will also be capable of processing 540 million cubic feet of gas per day, injecting 350,000 barrels of water per day, and storing approximately two million barrels of crude.
Production will increase progressively as wells are brought online. S&P Global Commodity Insights data reported by OilNOW projected that Uaru could initially produce approximately 136,000 b/d before ramping up to about 215,000 b/d in 2027. Even at the projected initial rate, Uaru would be sufficient to lift Guyana’s output beyond one million b/d if production from the four existing developments remains near current levels.
