The well was drilled about 12 miles west of the Aasta Hansteen field to prove petroleum in Upper Cretaceous reservoir rocks, in the Nise formation.
Well 6706/11-2 was drilled to a vertical depth of 8,385 feet below the sea surface and was terminated in the Nise formation in the Upper Cretaceous in water depths of 4,173 feet.
The well encountered a total gas column of about 229 feet in the Nise formation, with about 131 feet being sandstone with “very good reservoir quality,” according to the Norwegian Petroleum Directorate (NPD).
The find is Statoil’s third consecutive discovery at the Aasta Hansteen area in three months and is the second exploration well in production licence 602.
Preliminary estimates place the size of the discovery between one and three billion standard cubic meters of recoverable gas.
Statoil estimates recoverable resources in the Gymir prospect to be in the range of 6 to 19 million barrels of oil equivalent.
The well was not formation-tested, but extensive data acquisition and sampling have been carried out.
“The licensees will assess the discovery together with other discoveries in this production licence and the neighboring licence (218 with regard to development and tie-in to the Aasta Hansteen field,” the NPD said.
The well will now be permanently plugged and abandon.
Well 6706/11-2 was drilled by the Transocean Spitsbergen drilling facility that will now be laid up at Averøy outside Kristiansund.
The rig has completed its contract with Statoil.
“Our 2015 exploration campaign around Aasta Hansteen has proven an upside potential in the area. The discoveries will now be further evaluated for future tie-in to the Aasta Hansteen facilities in order to optimize utilization of the infrastructure and prolong the production plateau,” Statoil’s vice president exploration Norwegian and Barents Sea Dan Tuppen said.
Statoil holds a 40 percent operating stake in the license.
Norway’s Petoro holds a 20 percent stake, Centrica Resources Norge holds a 20 percent stake, Atlantic Petroleum Norge holds a 10 percent stake and Wintershall Norge holds a 10 percent stake.
