Global oil markets face tightening supplies and elevated prices amid geopolitical concerns and reduced inventories. Guyana has emerged as a significant contributor to global petroleum supply, reaching 908,000 barrels per day by late August 2026, positioning the nation as South America’s third-largest oil producer. The country achieved this milestone in approximately seven years following its initial commercial production startup in 2019, marking an exceptionally rapid development trajectory.
The offshore Stabroek Block, operated by ExxonMobil with a 45% stake alongside partners Chevron and CNOOC holding 30% and 25% respectively, has proven to be a prolific resource base. The block contains an estimated 11 billion barrels of recoverable oil and gas equivalent, supporting over 35 discoveries. Four floating production facilities currently operate in the region, with the One Guyana vessel commencing operations in August 2025 at the Yellowtail project. The Errea Wittu vessel arrived in late August 2026 and is scheduled to begin operations at the Uaru project before year-end, adding another 250,000 barrels daily.
Production is expected to surpass one million barrels daily by the end of 2026, with four additional projects—Whiptail, Hammerhead, Longtail, and Haimara—scheduled for startup between late 2026 and 2031. These facilities will contribute an additional 650,000 barrels of crude oil, 510,000 barrels of condensate, and three billion cubic feet of natural gas daily. By decade’s end, Guyana’s output is projected to reach approximately two million barrels of oil equivalent per day.
Guyana’s petroleum expansion is generating substantial economic benefits. First-half 2026 oil exports reached $15 billion, representing an 82% increase year-over-year. Annual petroleum revenues are forecast to approach $6.5 billion. The International Monetary Fund predicts Guyana’s GDP will expand 22.3% in 2026, making it the world’s fastest-growing economy. Since petroleum production commenced in 2019, the nation’s GDP has grown nearly eightfold to approximately $40 billion, elevating it to the continent’s highest per capita wealth and the 10th globally on that basis.
Approximately 60% of Guyana’s oil exports are directed toward Europe, with roughly one-third destined for the United States. This geographic distribution provides an alternative supply source for regions affected by Middle East supply disruptions, contributing to broader energy security across the Americas and globally.
