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 StenaCarron 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%).
