ExxonMobil has increased its estimated recoverable resource base in Guyana to more than 8 billion oil-equivalent barrels and made a further oil discovery northeast of the producing Liza field at the Uaru exploration well, the 16th discovery on the Stabroek Block.
The new recoverable resource estimate includes 15 discoveries offshore Guyana through year-end 2019. The Uaru discovery is the first of 2020 and will be added to the resource estimate at a later date.
“The Uaru discovery is another positive step as we begin a new decade with the Co-operative Republic of Guyana and our co-venturers,” said Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil.
Uaru encountered approximately 94 feet (29 meters) of high-quality oil-bearing sandstone reservoir. The well, drilled in 6,342 feet (1,933 meters) of water, is located approximately 10 miles (16 kilometers) northeast of the Liza field, which began producing oil in December 2019.
Production from the Liza Phase 1 development is currently ramping up and will produce up to 120,000 barrels of oil per day in the coming months, utilizing the Liza Destiny floating production storage and offloading vessel (FPSO).
Four drillships in Guyana continue to explore and appraise new resources as well as develop the resources within approved projects. A fifth drillship is expected to be deployed later this year.
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 Limited, holds 30 percent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 percent interest.
