Hess Guyana Drilling Operations Map

World Class Petroleum Province, Offshore Guyana

The Stabroek Block, located approximately 120 miles offshore Guyana, is 6.6 million acres. The block is equivalent in size to 1,150 Gulf of Mexico blocks and contains multiple prospects and play types representing additional multibillion barrel unrisked exploration potential. Hess has a 30 percent interest; ExxonMobil is the operator.


Gross discovered recoverable resources for the Stabroek Block are currently estimated at more than 11 billion barrels of oil equivalent with multi-billion barrels of exploration potential remaining. Based on the discoveries on the block to date, six floating production, storage and offloading (FPSO) vessels with gross production capacity of more than 1.2 million gross barrels of oil per day are expected to be online by the end of 2027 with potential for up to 10 FPSOs to develop the discovered resources on the block.


The Liza Phase 1 development delivered first production in December 2019 utilizing the Liza Destiny FPSO. Production optimization work in 2022 expanded its production capacity to more than 140,000 gross barrels of oil per day.


The Liza Phase 2 development, sanctioned in May 2019, achieved first production in February 2022 utilizing the Liza Unity FPSO with gross production capacity of approximately 220,000 barrels of oil per day. A third development, at the Payara Field was sanctioned in September 2020 and achieved first production in November 2023 utilizing the Prosperity FPSO, which added 220,000 gross barrels of oil per day of production capacity to the Stabroek Block.


The fourth and largest development on the Stabroek Block at Yellowtail was sanctioned in April 2022 with first oil expected in 2025. Yellowtail will utilize the ONE GUYANA FPSO with a production capacity of approximately 250,000 gross barrels of oil per day.

Uaru, the fifth development on the Stabroek Block, was sanctioned in April 2023. Uaru will utilize the Errea Wittu FPSO with a production capacity of approximately 250,000 gross barrels of oil per day. Production is targeted to startup in 2026.

Pursuing Play Extension in Suriname

In 2016, Hess acquired a one-third non-operated interest in the Block 42 contract area, which is located offshore Suriname along the northeast margin of South America. Deepwater Block 59, which is to the north and contiguous to Block 42, was awarded to Hess and co-venture partners ExxonMobil and Equinor in 2017.
