ExxonMobil today said it had made an oil discovery offshore Guyana at the Mako-1 well southeast of the Liza field, marking the 15th discovery on the Stabroek Block.
Mako-1 found approximately 164 feet (50 meters) of a high-quality oil bearing sandstone reservoir. Mako-1, drilled in 5,315 feet (1,620 meters) of water, is sited approximately six miles (10 kilometers) southeast of the Liza field, which began producing oil in December 2019.
“New discoveries in this world-class basin have the potential to support additional developments,” said Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil. “Our proprietary full-wave seismic inversion technology continues to help us better define our discovered resource and move rapidly to the development phase.”
The Liza Unity FPSO, which will be utilised for the second phase of Liza development and will have a production capacity of 220,000 barrels of oil per day, is under construction and expected to start production by mid-2022.
Pending government approvals and project clearance of a third development, production from the Payara field north of the Liza discoveries could start as early as 2023, reaching an estimated 220,000 barrels of oil per day.
Drilling activities in Guyana continue with four drillships to further explore and evaluate new resources as well as develop the resources within approved projects.
