Hess announced another oil discovery offshore Guyana at the Redtail-1 well, the 18th discovery on the Stabroek Block, which will add to the previously announced gross discovered recoverable resource estimate for the block of more than 8 billion barrels of oil equivalent.

Redtail-1 encountered approximately 232 feet (70 meters) of high quality oil bearing sandstone and was drilled in 6,164 feet (1,878 meters) of water. The well is located approximately 1.5 miles (2.5 kilometers) northwest of the Yellowtail discovery and is the ninth discovery in the southeast area of the block.

In addition to the Redtail-1 discovery, drilling at Yellowtail-2 resulted in the discovery of additional reservoir intervals adjacent to and below the Yellowtail-1 discovery. Yellowtail-2 encountered 69 feet (21 meters) of high quality oil bearing reservoirs, which comprise the 17th discovery on the Stabroek Block. This resource is currently being evaluated for development in conjunction with other nearby discoveries.

“The Redtail-1 and Yellowtail-2 discoveries further demonstrate the significant exploration potential of the Stabroek Block and will add to the recoverable resource estimate of more than 8 billion barrels of oil equivalent,” CEO John Hess said. “Redtail is the ninth discovery in the southeast area of the block which we expect will underpin future development.”

The Stabroek Block is 6.6 million acres. ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45 percent interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30 percent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 percent interest.
