ExxonMobil has made a discovery at the Pinktail well, on Guyana’s offshore Stabroek Block.
Pinktail found 220 feet (67 metres) of net pay, the US company said, while reporting another 43 feet (13 metres) of net pay at the Turbot-1 well. This comes in addition to the 75 feet (23 metres) of oil-bearing pay at the original Turbot-1 well.
“These discoveries are part of an extensive well programme 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,” said Exxon senior vice president of exploration and new ventures Mike Cousins.
“Our exploration successes continue to increase the discovered resource and will generate value for both the Guyanese people and our shareholders.”
Pinktail is 35 km southeast of Liza Phase 1 and 6 km southeast of Yellowtail-1. The Noble Sam Croft drilled Pinktail in 1,810 metres of water.
The Turbot-2 well was drilled 60 km southeast of Liza Phase 1 and 4 km from the Turbot-1 discovery, which was drilled in October 2017. The Noble Sam Croft drilled the Turbot-2 in 1,765 metres of water.
Hess CEO John Hess noted that Pinktail was the “20th significant discovery on the Stabroek Block, which will add to the discovered recoverable resource estimate of more than 9 billion barrels of oil equivalent”.
In addition, the Liza Unity floating production, storage and offloading (FPSO) vessel left Singapore early this month.
The Liza Unity is the first vessel from SBM Offshore’s Fast4Ward programme.
The company will use this vessel for the Liza Phase 2 development, which is due to start in early 2022. This next phase off Guyana will have 220,000 barrels per day of oil capacity. The first FPSO, the Liza Destiny, is producing 120,000 bpd.
Exxon discovered Liza in 2015. It began producing in 2019.
Exxon said it expects there to be six projects online by 2027. This could rise to 10, in order to develop all the discovered resources.
Exxon operates Stabroek via its Esso Exploration and Production Guyana unit, which has a 45% stake. Hess Guyana has 30% and CNOOC Petroleum Guyana 25%.
The US supermajor is also looking beyond Stabroek. It spudded a well on Guyana’s Canje Block in August.
