ExxonMobil reports it has made a discovery at Pinktail in the Stabroek Block offshore Guyana. The Pinktail well encountered 67 metres of net pay in high quality hydrocarbon bearing sandstone reservoirs.

In addition to successful appraisal of the Turbot discovery, the Turbot-2 well encountered 13 metres of net pay in a newly identified, high quality hydrocarbon bearing sandstone reservoir separate from the 23 metres of high-quality, oil-bearing sandstone reservoir pay encountered in the original Turbot-1 discovery well. This follows the additional pay in deeper reservoirs encountered at the previously announced Whiptail discovery. These results will be incorporated into future developments.

“These discoveries are part of an extensive well program in the Stabroek Block utilising six drillships to test play extensions and new concepts, evaluate existing discoveries and complete development wells for the Liza Phase 2 and Payara projects,” says Mike Cousins, senior vice president of exploration and new ventures at ExxonMobil. “Our exploration successes continue to increase the discovered resource and will generate value for both the Guyanese people and our shareholders.”

Separately, the Liza Unity floating production storage and offloading (FPSO) vessel set sail from Singapore to Guyana in early September. The FPSO will be utilised for the Liza Phase 2 development and is expected to begin production in early 2022, with a capacity to produce approximately 220,000 barrels of oil per day. ExxonMobil anticipates at least six projects online by 2027 and sees potential for up to 10 projects to develop its current discovered recoverable resource base. The Liza Destiny FPSO vessel is currently producing approximately 120,000 barrels of oil per day.

The Pinktail discovery is located approximately 35 kilometres southeast of the Liza Phase 1 project, which began production in December 2019, and 6 kilometres southeast of Yellowtail-1. Pinktail was drilled in 1,810 metres of water by the Noble Sam Croft. The Turbot-2 discovery is located approximately 60 kilometres to the southeast of the Liza phase one project, and 4 kilometres from the Turbot-1 discovery announced in October 2017. Turbot-2 was drilled in 1,765 metres of water by the Noble Sam Croft.

The Stabroek Block is 26,800 square kilometres. ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45% interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Limited holds 25% interest.
