ExxonMobil Guyana Limited advanced its programme at the Uaru development while the Yellowtail field moved into full operation. Work at the Uaru development moved into a new phase on 17 November 2025, when the company initiated drilling at the UA_3i02 Drill Center within the Stabroek Block of Guyana’s Exclusive Economic Zone.
Data from the Maritime Administration Department confirms that the MODU Noble Bob Douglas is overseeing the drilling campaign, which is scheduled to continue until 31 December 2025. The UA_3i02 site lies nearly 105.1 nautical miles (194.6 km) offshore, covering an area close to one square kilometre.

The $12.7 billion Uaru development is engineered to deliver up to 250,000 barrels per day once production begins in 2026. Current plans outline as many as 10 drill centers and 44 wells, targeting more than 800 million barrels of recoverable resources.
Supporting infrastructure is progressing in parallel. Japan’s MODEC is building the Errea Wittu FPSO, the unit designated to process and store production from Uaru. Completion of the vessel is essential as operations transition beyond Yellowtail and move into the next scheduled stage of offshore output.
