The updated resource estimate includes another significant discovery on the Stabroek block at the Cataback well. The well encountered 243 ft (74 m) of net pay in high quality hydrocarbon bearing sandstone reservoirs of which 102 ft (31 m) is oil bearing. Cataback is located approximately 3.7 miles (6 km) east of Turbot-1 and was drilled in 5928 ft (1807 m) of water by the Noble Tom Madden.
CEO John Hess said: “We are pleased that Cataback is our 21st significant discovery on the Stabroek Block and further underpins the potential for future developments. We continue to see multibillion barrels of additional exploration potential remaining on the block.”
