Statoil has drilled a dry well on the Spinell Sor prospect in the Norwegian North Sea. The primary exploration target for the well was to delineate the 6407/4-1 gas/condensate discovery.
The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks in the Ile formation. Reservoir rocks in the Garn formation in the primary target were encountered with poorer reservoir quality than expected; and the secondary target in the Ile formation had reservoir rocks with the expected reservoir quality, however, both exploration targets are water-bearing.
Drilled by the Transocean Leader semsiub, the 6407/4-2 well was drilled to a vertical depth of 13,802 feet (4,207 meters), terminating in the Ile formation in the Middle Jurassic. The well will now be plugged and abandoned. The licensees in production license 429 are Statoil (operator, 70%) and Dong (30%).
