ExxonMobil to carry out appraisal of latest Guyana discovery

ExxonMobil will carry out a 'comprehensive' appraisal process of the newly discovered reservoir encountered by the Lancetfish-2 appraisal well in the Liza petroleum production license area, the country’s Ministry of Natural Resources said last week.  

The Ministry's release comes following partner Hess Corp.’s third-quarter 2023 earnings statement in which it detailed Lancetfish-2 (OGJ Online, Oct. 25, 2023). Hess said the appraisal well encountered about 125 ft of net oil pay in appraisal reservoirs and about 65 ft of net oil pay in a new discovery interval.

The well was drilled in 5,649 ft of water and lies about 4 miles southeast of the Lancetfish-1 discovery well, which—drilled by the Noble Don Taylor—encountered about 92 ft of high-quality oil-bearing sandstone. That well was drilled in 5,843 ft of water and is about 4 miles southeast of the Fangtooth discovery.

ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. is operator and holds 45% interest in Stabroek block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Ltd. holds 25% interest.
