Oil production offshore Guyana has climbed to 900,000 barrels per day (bpd), operator ExxonMobil said on Wednesday.
The boost comes as the Yellowtail development, which began production in August, reached its initial capacity of 250,000 bpd. The increase combines with higher-than-planned production from the Liza 1, Liza 2 and Payara projects, all located in the prolific Stabroek Block.
Exxon and its partners Hess (now owned by Chevron) and China’s CNOOC have committed to invest more than US$60 billion to develop seven government-approved projects in the block, including Uaru, Whiptail and Hammerhead.
Uaru and Whiptail, each designed to produce about 250,000 bpd, are scheduled to begin operations in 2026 and 2027 respectively. Hammerhead, expected online in 2029, will add roughly 150,000 bpd. A proposed eighth project, Longtail, is under regulatory review and targeted for a 2030 startup.
Once all eight projects are producing, total capacity offshore Guyana is expected to reach about 1.7 million bpd, Exxon said.
Analyst firms such as Americas Market Intelligence have said that the addition of the Yellowtail project makes Guyana the world’s largest oil producer per capita.
