ExxonMobil increases Guyana recoverable resources

11 February 2020

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 the year-end 2019. The Uaru discovery is the first of 2020 and will be added to the resource estimate at a later date.

Uaru encountered approximately 94 feet (29 meters) of a 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).

The Liza Unity FPSO, which will be employed for the second phase of Liza development and will have a production capacity of 220,000 barrels of oil per day, is expected to start production by mid-2022.
