ExxonMobil plans to carry out a fresh exploration programme soon in the Stabroek block offshore Guyana that is expected to test the prospectivity of deeper reservoirs in the prolific play.

According to project partner, US independent Hess, which holds a 30% working interest at Stabroek, the consortium intends to spud the Fangtooth-1 wildcat by the end of the year.

“This well is a significant step out test that will target deeper Campanian and Santonian aged reservoirs,” Hess chief operating officer Greg Hill told investors in a conference call.

Hill refrained from providing additional information, just saying Fangtooth-1 is located about 14 kilometres north-west of the giant Liza field.

He also said one of the consortium’s main objectives for 2022 is to target deeper horizons at Lower Campanian and Upper Santonian reservoirs with new exploration wells in the Stabroek block.

Appraisal activities will continue in the fourth quarter, he added, with ExxonMobil set to spud the Tripletail-2 well and run drillstem tests at the Longtail-2 and Whiptail-2 discoveries.

ExxonMobil has four Noble Corporation drillships — Noble Sam Croft, Noble Bob Douglas, Noble Don Taylor and Noble Tom Madden — as well as the Stena Drilling drillships Stena Carron and Stena DrillMax operating in Guyana.

Hess reported a net profit of $115 million in the third quarter, compared with a net loss of $243 million a year ago. Hydrocarbons production, excluding Libya, fell 17.5% to 265,000 barrels of oil equivalent per day.
