Hess announces two discoveries offshore Guyana

The Seabob-1 well encountered approximately 131 feet (40 m) of high quality oil bearing sandstone reservoirs. The well was drilled in 4 660 ft (1421 m) of water by the Stena Carron and is located approximately 12 miles (19 km) southeast of the Yellowtail Field.

The Kiru-Kiru-1 well encountered approximately 98 feet (30 m) of high quality hydrocarbon bearing sandstone reservoirs. The well was drilled in 5760 feet (1756 m) of water by the Stena DrillMAX and is located approximately 3 miles (5 km) southeast of the Cataback-1 discovery. Drilling operations at Kiru-Kiru are ongoing.

“We are excited to announce two more discoveries on the Stabroek Block, bringing our total this year to seven,” CEO John Hess said. “These discoveries will add to the discovered recoverable resource estimate for the block of approximately 11 billion barrels of oil equivalent, and we continue to see multibillion barrels of future exploration potential remaining.”

Hess and its co-venture partners currently have four sanctioned developments on the Stabroek Block. The Liza Phase 1 development, which began production in December 2019, reached its new production capacity of more than 140 000 gross barrels of oil per day in the second quarter of 2022 following production optimisation work on the Liza Destiny floating production, storage and offloading vessel (FPSO). The Liza Phase 2 development, which achieved first oil in February 2022 utilising the Liza Unity FPSO, reached its production capacity of approximately 220 000 gross barrels of oil per day earlier this month. The third development at Payara is on track to come online in late 2023 utilising the Prosperity FPSO with a production capacity of approximately 220 000 gross barrels of oil per day. The fourth development, Yellowtail, will be the largest development to date and is expected to come online in 2025, utilising the ONE GUYANA FPSO with a production capacity of approximately 250 000 gross barrels of oil per day.

At least six FPSOs with a production capacity of more than 1 million gross barrels of oil per day are expected to be online on the Stabroek Block in 2027, with the potential for up to 10 FPSOs to develop gross discovered recoverable resources.

The Stabroek Block is 6.6 million acres. ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45% interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Limited holds 25% interest.
