The new Barreleye-1 well, drilled in 3,840 feet of water, found roughly 230 feet of hydrocarbon-bearing sandstone reservoirs, 52 feet of which is high quality oil bearing. The well is located about 20 miles southeast of the original Liza Field which is the first oil development at Guyana’s Stabroek Block.
The drill campaign at Barreleye-1 had started in January but was not completed then.
“Drilling of the Barreleye well on the Stabroek Block was temporarily suspended for operational reasons. We are now resuming activities,” ExxonMobil Guyana’s Media and Communication Manager Janelle Persaud told OilNOW in March.
The Lukanani-1 well, sited in water depths of about 4,068 feet, found 115 feet of hydrocarbon-bearing sandstone reservoirs of which around 76 feet is high quality oil bearing. The well is located in the southeastern part of the block, about two miles west of the Pluma discovery, announced in December 2018.
The Patwa-1 well, drilled in 6,315 feet of water, found 108 feet of hydrocarbon bearing sandstone reservoirs. The well is sited about three miles northwest of the Cataback discovery.
“These discoveries and the updated resource estimate increase the confidence we have in our ambitious exploration strategy for the Stabroek Block and will help to inform our future development plans for the southeast part of the block,” said Liam Mallon, president of ExxonMobil Upstream Company.

The three new discoveries further show the “extraordinary resource density” of the Stabroek Block, Hess CEO John Hess said in a separate statement. The finds “will underpin our queue of future development opportunities,” he said.
The 6.6 million acres Stabroek Block is projected to have more than 20 billion oil equivalent barrels – double the current discovered resources – according to Exxon and analysts in the industry.
