ExxonMobil Strikes Oil At Tripletail Offshore Guyana

An approximately 108 feet (33 meters) of a high-quality oil-bearing sandstone reservoir was found at Tripletail-1, which is drilled in 6,572 feet (2,003 meters) of water. Tripletail-1 is located approximately 3 miles (5 kilometers) northeast of the Longtail discovery. Longtail discovery was ExxonMobil’s eighth oil discovery offshore Guyana at the Longtail-1 well in June 2018, which created the potential for additional resource development in the southeast area of the Stabroek Block. Noble Tom Madden drillship, which is currently completing operations at Tripletail, will drill next at the Uaru-1 well, which located approximately 6 miles east of the Liza field. ExxonMobil, together with its partners, is continuously deploying industry-leading innovations and capabilities to identify projects that can be developed effectively and in a cost-efficient way.

The global crude oil market was volumed at around 101.40 MB/d in 2025 and is expected to expand at a CAGR of 0.90% from 2026 to 2035, reaching approximately 110.90 MB/d by 2035.

With the advancement in technology, the exploration and development activities are moving forward elsewhere on the Stabroek Block offshore Guyana. While the Stena Carron drillship is currently drilling the Ranger-2 well, the Noble Bob Douglas drillship is involved in the development of drilling operations for the Liza Phase 1 project. After this, Stena Carron drillship will be utilised to conduct a well test at Yellowtail-1. Moreover, ExxonMobil will be deploying a fourth drillship, the Noble Don Taylor, which is expected to begin Guyana operations in October, aiming to further optimise company’s drilling plans, which will be based on well results and ongoing study of the basin.

As scheduled, the Liza Phase 1 project development will start by early 2020, producing up to 120,000 barrels of oil per day. The company will be utilising the Liza Destiny floating production storage and offloading (FPSO), which arrived in Guyana on August 29, 2019, in order to reach this production volume.

In May 2019, ExxonMobil received government and regulatory approvals for Liza Phase 2 development project, after which the company approved funding for the same. The project is expected to start by mid-2022, and the company has planned to use the Liza Unity FPSO for this project, aiming to produce up to 220,000 barrels of oil per day. A third development, Payara startup, though subject to regulatory approvals, is expected to start its operation by 2023, further aiding the company to reach an estimated production capacity of around 220,000 barrels of oil per day.
