Hess Announces Increased Resource Estimate for Stabroek Block, Offshore Guyana

Hess Corporation today announced an increased estimate of gross discovered recoverable resources for the Stabroek Block, offshore Guyana to more than 4 billion barrels of oil equivalent, up from the previous estimate of 3.2 billion barrels of oil equivalent.

The increase follows completion of testing at the Liza-5 appraisal well, a discovery at Ranger, incorporation of results from the eighth discovery on the Block at the Longtail exploration well into the Turbot area evaluation, and completion of the Pacora discovery evaluation. This evaluation supports a third phase of development and consideration of two additional phases. There is potential for additional development phases from significant undrilled targets and plans for rapid exploration and appraisal drilling, including at the Ranger discovery.

“The Stabroek Block is a massive world class resource that keeps getting bigger and better,” CEO John Hess said. “Since the end of 2016, the estimate for recoverable resources on the block has quadrupled and we continue to see multi billion barrels of additional exploration potential on the block. We believe the investment opportunity in Guyana has the potential to be transformative for our company and create significant value for our shareholders for many years to come.”
