Multiple Prospects and Play Types Offshore Guyana

The Stabroek Block, located approximately 120 miles offshore Guyana, is 6.6 million acres (26,800 square kilometers). 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. Esso E&P Guyana Ltd is the operator and has a 45 percent working interest, while Hess Guyana Exploration Ltd has 30 percent interest and CNOOC Petroleum Guyana Limited has 25 percent interest.


To date, 13 significant discoveries have been made on the block at Liza, Payara, Snoek, Liza Deep, Turbot, Ranger, Pacora, Longtail, Hammerhead, Pluma, Tilapia, Haimara and Yellowtail. Gross discovered recoverable resources for the Stabroek Block are currently estimated at more than 5.5 billion barrels of oil equivalent with multi-billion barrels of additional exploration potential on the block.

The Liza Phase 1 development, sanctioned June 2017, is progressing rapidly, laying the foundation for first production by the first quarter of 2020. Liza Phase 1 will produce up to 120,000 gross barrels of oil per day at peak rates utilizing the Liza Destiny floating production, storage and offloading (FPSO) vessel.

The second phase of the Liza development, sanctioned in May 2019, will utilize a second FPSO with gross production capacity of approximately 220,000 barrels of oil per day, with start-up expected by mid 2022. Planning is underway for a third phase of development, which is expected to be sanctioned in 2019 with startup projected in 2023.

In April 2018, Hess acquired a 15 percent interest in the Kaieteur Block, located approximately 155 miles (250 kilometers) offshore and adjacent to the Stabroek Block. The Kaieteur Block covers 3.3 million acres (13,535 square kilometers). Seismic interpretation and evaluation of a future drilling program are planned for 2018.

Pursuing Play Extension in Suriname

In 2016, Hess Suriname Exploration Limited, a wholly-owned subsidiary of Hess Corporation, 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. Kosmos Energy Suriname is the operator and has one-third working interest, while Hess Suriname Exploration Ltd. and Chevron Suriname Exploration each have one-third interest. An exploration well is planned for 2020.

Deepwater Block 59, which is to the north and contiguous to Block 42, was awarded to Hess Suriname Exploration Limited and co-venture partners ExxonMobil Exploration and Production Suriname B.V. and Equinor Suriname B59 B.V. in 2017. Each have a one-third interest and ExxonMobil Exploration and Production Suriname B.V. is the operator. In 2019, 2D seismic acquisition is planned.
