ExxonMobil’s Uaru development is the first Stabroek Block project to utilize a subsea tieback connecting three fields – Uaru, Mako, and Snoek oil fields – to a single production facility.
Tiebacks, by industry definition, transport hydrocarbons from seabed wells to a host platform via pipelines. This approach reduces the need for new offshore production platforms. Wells are drilled on the seabed and linked by flowlines to gathering systems. Hydrocarbons undergo minimal processing at the host platform before export.

Uaru was ExxonMobil’s 16th discovery in the block, announced in January 2020. The Uaru-1 well was drilled in 6,342 feet of water and found 94 feet of quality oil-bearing sandstone. The Mako discovery, the 15th in the block, was announced in December 2019. Mako-1 was drilled in 5,315 feet of water and hit 164 feet of oil-bearing sandstone. Snoek, discovered in March 2017, was Exxon’s third find in the Stabroek Block. The Snoek-1 well encountered 82 feet of oil-bearing sandstone at 5,128 feet of water depth.
The Uaru project was the fifth offshore development approved in Guyana. Valued at US$12.7 billion, it targets over 800 million barrels of oil. The development includes up to 10 drill centers and 44 wells. Initial production is expected to reach 250,000 barrels per day by 2026.
Japanese firm MODEC is building the FPSO for the project, named Errea Wittu.
