Stabroek output climbs further to 918,000 b/d in February

March 30 (oilnow.gy) Crude oil production offshore Guyana averaged about 918,000 barrels per day (b/d) in February 2026, reflecting continued gains from optimization work across ExxonMobil’s Stabroek Block developments.

Government data shows that approximately 25.7 million barrels were produced during the month across four projects. 

Output was distributed as follows: 

• Liza 1: 129,000 b/d
• Liza 2: 261,000 b/d
• Payara: 264,000 b/d 
• Yellowtail: 264,000 b/d

The February average marks a modest increase from January’s 915,000 b/d and stands as the highest monthly production rate recorded to date. It also highlights the steady ramp-up that began in late 2025, when Yellowtail reached its initial target rate of 250,000 b/d and subsequently safely surpassed it.

Yellowtail is now producing at an upper limit of roughly 263,000 b/d. ExxonMobil has indicated that it is awaiting government agreement to conduct a study that could support further increases, with the company assessing the potential to lift production at the project to 290,000 b/d.

Across the Stabroek Block, production levels are increasingly safely exceeding their initial targets as a result of debottlenecking, and reservoir management improvements. These efforts are allowing the operator to push output higher without major new infrastructure.

Average production for the full year 2025 stood at about 716,000 b/d, demonstrating the scale of growth in production that has occurred in recent months. The latest figures signal that Guyana’s offshore output is now approaching the one million barrel per day threshold.

That expansion is expected to accelerate further with projects set to begin production this year and the next. The Uaru project is designed to add 250,000 b/d to capacity before yearend. This will be followed by the Whiptail project in 2027, which is also expected to contribute 250,000 b/d, and the Hammerhead project in 2029, projected to add 150,000 b/d/. Hammerhead will add 90 million cubic feet per day (mcf/d) of natural gas to the 50 mcf/d set to flow through a pipeline to Wales later this year. 

Beyond oil-focused developments, ExxonMobil and its partners are advancing a series of gas-centered projects set to reshape the production profile of the block. The proposed Longtail development, currently under review, is expected to deliver about 1.2 billion cubic feet per day (bcf/d) of gas and approximately 250,000 b/d of condensate when it comes on stream around 2030.

The company is also preparing to initiate the application process for a ninth project, anchored by the Haimara discovery and incorporating volumes from the Pluma field. Both are gas-rich discoveries, reinforcing a broader shift toward monetizing the block’s substantial gas resources alongside oil production.

All offshore production in Guyana is currently operated by ExxonMobil, which holds a 45% stake in the Stabroek Block. Its co-venturers are Hess, now part of Chevron, with 30%, and China’s CNOOC with 25%.
