ExxonMobil made an oil discovery at Longtail-3 well in the Stabroek Block offshore Guyana, the company said in a statement on Wednesday.
The Longtail-1 discovery, drilled in 2018, encountered approximately 78 meters of high-quality, oil-bearing sandstone reservoir.
“Longtail-3, combined with our recent discovery at Uaru-2, has the potential to increase our resource estimate within the Stabroek block, demonstrating further growth of this world-class resource and our high-potential development opportunities offshore Guyana,” said Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil.
Six drillships now operate offshore Guyana, which includes the 26,800 square-kilometer Stabroek Block.
ExxonMobil affiliate Esso Exploration and Production Guyana Limited is the operator and holds a 45% interest in the Block. Hess Guyana Exploration Ltd. holds a 30% interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds a 25% interest.
