ExxonMobil and partners (Hess Corp. and CNOOC Ltd.) have made its 18th discovery offshore Guyana at the Redtail-1 well.
This will add to the previously announced estimated recoverable resource of more than 8 billion oil-equivalent barrels on the Stabroek Block.
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.
In addition to the Redtail-1 discovery, drilling at Yellowtail-2 encountered 69 feet (21 meters) of net pay in newly identified, high quality oil bearing reservoirs among the original Yellowtail-1 discovery intervals. This resource is currently being evaluated for development in conjunction with nearby discoveries.
