France’s Total E&P Norge’s appraisal well 34/6-3 S on the 34/6-2 S oil discovery and wildcat well 34/6-3 A hit two pay zones in the the North Sea but drilled dry in Statfjord formation.
The wells were drilled about 18 miles northeast of the Visund field in the northern North Sea in the Total operated production license 554.
Appraisal well 34/6-3 S was drilled to delineate the 34/6-2 S oil discovery made in the Cook formation in the Lower Jurassic in 2012.
Before drilling, the discovery was estimated at 6 million cubic meters recoverable oil.
A secondary target to prove petroleum in the Statfjord group in the Lower Jurassic was also drilled.
The primary target proved a total gross oil column of 120 meters in the Cook formation with a “very good” quality reservoir.
Preliminary calculation of the size of the oil discovery is between 6 and 14 million cubic meters of recoverable oil.
The secondary target in the Statfjord group came up dry.
The well was tested with a stable production rate of 940 standard cubic meters of oil per flow day through a 24/64-inch nozzle opening, with a maximum production rate of 1,100 standard cubic meters oil per flow day through a 28/64-inch nozzle opening.
Statoil is undertaking extensive data analyse to confirm the resource estimate and assess possible development solutions.
Wildcat well 34/6-3 A also hit a pay zone in its primary target.
The well encountered a 12 meter net oil column in the Cook formation with recoverable resources estimated at up to 500,000 standard cubic meters of oil.
The secondary exploration target to prove petroleum in the Statfjord group in the Lower Jurassic drilled dry.
Well 34/6-3 S was drilled to a measured depth of 14,639 feet to the Statfjord group in the Early Jurassic. Well 34/6-3 A was drilled to a measured depth of 13,185 feet under the sea surface.
The wells will be permanently plugged and abandoned.
