ExxonMobil Guyana Produced 892,000 B/D in December

• ExxonMobil Guyana averaged 892,000 barrels per day (b/d) of crude oil production in December 2025 across its four producing developments in the Stabroek Block, according to newly released government data. Production by project was 130,000 b/d at Liza 1, 244,000 b/d at Liza 2, 256,000 b/d at Payara, and 262,000 b/d at Yellowtail.
• Yellowtail, the newest development, began producing oil in August and reached its initial production capacity of 250,000 b/d in November. The project’s ramp-up was the primary driver of higher overall output in the final months of the year. December’s average compares with 894,000 b/d in November and 841,000 b/d in October, reflecting the step change in output after Yellowtail stabilised. For the full year, crude oil production from the Stabroek Block averaged 716,000 b/d.
• Liza 1 showed signs of natural decline during the year, falling from highs of around 160,000 b/d in some months of 2024 to 130,000 b/d in December 2025, consistent with the typical production profile of offshore oil projects that move from ramp-up to plateau and then gradual decline.
• A new Stabroek Block project, Uaru, is due to start production this year, adding 250,000 b/d to capacity. All offshore production in Guyana is operated by ExxonMobil, which holds a 45% stake in the Stabroek Block. Co-venturers include Hess, now part of Chevron, with 30%, and China National Offshore Oil Corporation CNOOC with 25%.
