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 Nexen Petroleum Guyana Ltd. has 25 percent interest.
To date, eight significant discoveries have been made on the block at Liza, Payara, Snoek, Liza Deep, Turbot, Ranger, Pacora and Longtail.
Hess and its co-venture partners believe there are multi-billion barrels of additional exploration potential on the block.
Development drilling at the Liza Phase 1 development, sanctioned June 2017, is underway, laying the foundation for first production in early 2020. Liza Phase 1 will consist of 17 wells connected to a floating production, storage and offloading (FPSO) vessel designed to produce up to 120,000 barrels of oil per day.
The second phase of the Liza development 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. A third phase of development is planned to closely follow Liza Phase 2 and is expected to bring gross production to more than 500,000 barrels of oil per day by late 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.
