ExxonMobil reports it made an oil discovery on the Stabroek Block offshore Guyana at the Tripletail-1 well in the Turbot area. The discovery adds to the previously announced estimated recoverable resource of more than 6 billion oil-equivalent barrels on the Stabroek Block.
Tripletail-1 encountered approximately 33 metres of a high-quality oil-bearing sandstone reservoir. Tripletail-1, drilled in 2,003 metres of water, is located approximately 5 kilometres northeast of the Longtail discovery. After completion of operations at Tripletail, the Noble Tom Maddendrillship will next drill the Uaru-1 well, located approximately 10 kilometres east of the Liza field.
“This discovery helps to further inform the development of the Turbot area,” says Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil. “Together with our partners, ExxonMobil is deploying industry-leading capabilities to identify projects that can be developed efficiently and in a cost-effective way.”
Exploration and development activities are moving forward elsewhere on the Stabroek Block offshore Guyana. The Stena Carron drillship is currently drilling the Ranger-2 well and upon completion will conduct a well test at Yellowtail-1. The Noble Bob Douglas drillship is currently completing development drilling operations for the Liza Phase 1 project. ExxonMobil will add a fourth drillship, the Noble Don Taylor, in October 2019 as it continues to optimise drilling plans based on well results and ongoing study of the basin.
The Liza Phase 1 development remains on schedule to start up by early 2020 and will produce up to 120,000 barrels of oil per day utilising the Liza Destiny floating production storage and offloading (FPSO), which arrived in Guyana on August 29, 2019.
ExxonMobil approved funding for the Liza Phase 2 development after it received government and regulatory approvals in May 2019. Expected to start-up by mid-2022, the project plans to use the Liza Unity FPSO to produce up to 220,000 barrels of oil per day. Pending government approvals, a third development, Payara start-up could be as early as 2023 and production would reach an estimated 220,000 barrels of oil per day.
The Stabroek Block is 26,800 square kilometres. 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, a wholly owned subsidiary of CNOOC Limited, holds 25% interest.
