The drillship Stena Carron drilled the Payara-1 well roughly 10 mi (16 km) northwest of the Liza discovery, encountering more than 95 ft (29 m) of good-quality, oil-bearing sandstone reservoirs.
Drilling started on Nov. 12, 2016, with a TD of 18,080 ft (5,512 m) in 6,660 ft (2,030 m) of water, followed by two side tracks. The partners plan a production test to evaluate the find and further appraisal drilling later this year.
Hess added that the Liza-3 appraisal well, completed in November, identified another good-quality, deeper reservoir directly below the Liza field that is estimated to contain 100-150 MMboe. This resource will likely be part of the full Liza field development.
John Hess, CEO of Hess, said: “While further appraisal is required, we believe that the resources recently discovered are significant and will be accretive to the more than 1 Bboe already confirmed at the Liza discovery.”
On completion of operations at Payara-1, the Stena Carron will transfer to spud the Snoek exploration prospect, 6 mi (10 km) south of Liza-1.
