Tripletail-1 faced around 108 feet (33 meters) of a high-quality oil bearing sandstone reservoir. Tripletail-1, drilled in 6,572 feet (2,003 meters) of water, is located around 3 miles (5 kilometers) northeast of the Longtail discovery.

After completing operations at Tripletail, the Noble Tom Madden drillship will next drill the Uaru-1 well, located about 6 miles (10 kilometers) east of the Liza field.

This discovery helps to further inform the development of the Turbot area. Together with our partners, ExxonMobil is deploying industry-leading capabilities to identify projects that can be developed efficiently and in a cost-effective way

states Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil.


Exploration and development activities are now proceeding elsewhere on the Stabroek Block offshore Guyana. The Stena Carron drillship is now drilling the Ranger-2 well and when completed, it will perform a well test at Yellowtail-1.

In addition, the Noble Bob Douglas drillship is finalizing development drilling operations for the Liza Phase 1 project. ExxonMobil will also add a fourth drillship, the Noble Don Taylor, in October 2019, while at the same time continuing to improve its drilling plans according to well results and study of the basin.

What is more, the Liza Phase 1 development is planned to begin by early 2020 and will be able to produce up to 120,000 barrels of oil per day using the Liza Destiny floating production storage and offloading (FPSO), which arrived in Guyana on August 29, 2019.

ExxonMobil had approved funding for the Liza Phase 2 development when it received government and regulatory approvals back in May 2019. Forecast to startup by mid-2022, the project aims to use the Liza Unity FPSO to produce up to 220,000 barrels of oil per day.

Awaiting for government approvals, a third development, Payara startup could be as early as 2023 and production would reach around 220,000 barrels of oil per day.

The Stabroek Block is 6.6 million acres (26,800 square kilometers).
