Hess has made a tenth discovery offshore Guyana at the Pluma-1 well on the Stabroek Block.

As a result of this new discovery and further evaluation of previous discoveries, the estimate of discovered recoverable resources for the Stabroek Block has been increased to more than 5 billion barrels of oil equivalent, up from the previous estimate of more than 4 billion barrels of oil equivalent announced in July 2018.

Pluma-1 encountered approximately 121 feet (37 meters) of high-quality, hydrocarbon-bearing sandstone reservoir. Pluma-1 reached a depth of 16,447 feet (5,013 meters) in 3,340 feet (1,018 meters) of water. The Noble Tom Madden drillship began drilling on Nov. 1. The well is located approximately 17 miles (27 kilometers) south of the Turbot-1 well. The Noble Tom Madden will next drill the Tilapia-1 prospect located 3.4 miles (5.5 kilometers) west of the Longtail-1 well.
