ExxonMobil has announced that it made an oil discovery offshore Guyana at the Mako-1 well southeast of the Liza field, marking it the 15th discovery on the Stabroek Block.

The discovery adds to the previously announced estimated recoverable resource of more than 6 billion oil-equivalent barrels on the Stabroek Block.

According to the company, Mako-1 encountered 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 located approximately six miles (10 kilometers) southeast of the Liza field.

Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil, said “New discoveries in this world-class basin have the potential to support additional developments”. “Our proprietary full-wave seismic inversion technology continues to help us better define our discovered resource and move rapidly to the development phase”, he added.
