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, 12 significant discoveries have been made on the block at Liza, Payara, Snoek, Liza Deep, Turbot, Ranger, Pacora, Longtail, Hammerhead, Pluma, Tilapia and Haimara. Gross discovered recoverable resources for the Stabroek Block are currently estimated at approximately 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 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. Planning is underway for a third phase of development, which is targeted to be sanctioned in 2019 and will use an FPSO designed to produce approximately 180,000 barrels of oil per day, with first production as early as 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 is the operator and has 33.3 percent working interest, while Hess Suriname Exploration Ltd. and Chevron Corporation each have 33.3 percent interest. 3-D seismic has been acquired and is being interpreted.

Deepwater Block 59, which is to the north and contiguous to Block 42, was awarded to Hess and co-venture partners ExxonMobil and Statoil in 2017. Each have a one-third interest and Exxon is the operator. In 2018, seismic acquisition is planned.

Hess Exploration Drilling in Nova Scotia

An Emerging Play in Nova Scotia

Hess has partnered with operator BP to explore four deepwater licenses offshore Nova Scotia, which combined are equal in size to 600 deepwater Gulf of Mexico OCS blocks. Although a frontier area, based on 3D seismic data the geology appears analogous to deepwater Gulf of Mexico. Exploration drilling commenced in 2018. Hess has a 50 percent working interest.
