ExxonMobil announces discovery at Uaru-2 offshore Guyana

• Guyana potential increases to as many as 10 floating production storage and offloading vessels (FPSO)
• Estimated recoverable resource of approximately 9 billion oil-equivalent barrels to increase
• Six drillships now operating offshore Guyana

“The Uaru-2 discovery enhances our work to optimally sequence development opportunities in the Stabroek Block,” said Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil. “Progressing our industry-leading investments and well-executed exploration plans are vital in order to continue to develop Guyana’s offshore resources that unlock additional value for the people of Guyana and all stakeholders.”

In January 2020, ExxonMobil announced that Uaru-1 was the 16th discovery in the Stabroek Block. The well encountered approximately 94 feet (29 meters) of high-quality oil-bearing sandstone reservoir and was drilled in 6,342 feet (1,933 meters) of water. 

In March 2021, ExxonMobil secured a sixth drillship, the Noble Sam Croft, for exploration and evaluation drilling activities offshore Guyana. A fourth project, Yellowtail, has been identified within the block with anticipated start up in late 2025 pending government approvals and project sanctioning. This project will develop the Yellowtail and Redtail fields, which are located about 19 miles (30 kilometers) southeast of the Liza developments.

ExxonMobil anticipates at least six projects online by 2027 and sees potential for up to 10 FPSOs to develop its current recoverable resource balance.

The start-up of Liza Phase 2 remains on target for 2022, as the Liza Unity FPSO prepares for sail away from Singapore to Guyana later this year. The Unity FPSO has a production capacity of 220,000 barrels of oil per day at peak rates. The hull for the Prosperity FPSO vessel, the third project at the Payara Field, is complete, and topsides construction activities have commenced in Singapore with a startup target of 2024.

These new projects continue to drive investment in the Guyanese economy. More than 2,300 Guyanese are now supporting project activities on and offshore, which reflects a more than 20 percent increase since the end of 2019. ExxonMobil and its key contractors have spent approximately US$388 million with more than 800 local companies since 2015. 

The Stabroek Block is 6.6 million acres (26,800 square kilometers). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45 percent interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30 percent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 percent interest.
