Exxon strikes oil in Longtail-3 discovery

Georgetown: ExxonMobil on Wednesday announced that it made a discovery at Longtail-3 in the Stabroek Block offshore Guyana.

Drilling at Longtail-3 encountered 230 feet (70 meters) of net pay, including newly identified, high quality hydrocarbon bearing reservoirs below the original Longtail-1 discovery intervals. The well is located approximately two miles (3.5 kilometers) south of the Longtail-1 well. It was drilled in more than 6,100 feet (1860 meters) of water by the Stena DrillMAX.

“Longtail-3, combined with our recent discovery at Uaru-2, has the potential to increase our resource estimate within the Stabroek block, demonstrating further growth of this world-class resource and our high-potential development opportunities offshore Guyana,” said Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil. “We will continue to leverage our core competitive advantages in our ongoing exploration campaign, delivering substantial value to the Guyanese people, our partners and shareholders.”

The Government of Guyana in a statement said it anticipates that this new development will further increase the potential for more floating production storage and offloading vessels (FPSO). Additionally, this will increase the estimated recoverable resource given by the operator, Esso Exploration and Production Guyana Limited (EEPGL).

“As such, the Ministry and the Petroleum Sector regulatory agencies will continue to work with other operators to expedite their drill programme as we seek to expand the sector,” Minister of Natural Resources, Vickram Bharrat said.

The Longtail-1 discovery in the Stabroek Block was drilled in 2018, encountering approximately 256 feet (78 meters) of high-quality, oil-bearing sandstone reservoir.
