ExxonMobil's Liza discovery, offshore Guyana, has upped its potential due to the company's successful run at the Liza-3 appraisal well, according to partner Hess Corp.

The Liza-3 appraisal well on the Stabroek Block was successfully completed, and is now expected to be on the upper end of the scale.
“Based on the positive results of the Liza-3 well, we now expect Liza to be at the upper end of the previously announced estimated recoverable resources range of 800 MMboe to 1.4 billion boe,” Hess CEO John Hess said.
Liza-3 well is in the Stabroek block, about 193km offshore Guyana. The Liza wells are being drilled with the Stena Carron harsh environment drillship.
In late June, Exxon’s drilling results at Liza-2 revealed more than 58m of oil-bearing sandstone reservoirs in Upper Cretaceous formations. The well was drilled to 5475m at 1692m water depth. Drilling results confirmed recoverable resources to be between 800 MMboe – 1.4 billion boe. Data from the Liza-2 well test is being assessed.
In May 2015, Exxon confirmed its significant oil discovery at its Liza-1 exploration well, where the well encountered more than 295ft of high quality oil-bearing sandstone reservoirs.
Stabroek is operated by Esso E&P Guyana with 45% interest. Partners include Hess (30%), and CNOOC Nexen Petroleum Guyana (25%).
