LONDON, June 30 -- StatoilHydro is considering tying in its discovery of 5.6-12.5 million boe of recoverable oil in the Tampen area of the Norwegian North Sea to its Visund project.
Exploration wells 34/8-13 A and 34/8-13 S, drilled to test Brent group targets, made the discovery on the Titan prospect directly east of northern Visund.
“Although it’s only a small find, the volumes proven could be very significant for realizing a Visund North development,” said Visund operations head Tom Karsten Gustavsen.
Visund field produces oil and gas from subsea wells tied to a floating production, storage, and quarters platform. North Visund is a separate subsea development about 10 km north of the platform.
While 13 A on the Titan prospect found a small oil column in Upper Jurassic sands, the underlying Brent group proved to be an aquifer. Well 13 S, drilled 2.7 km to the southeast, found oil in the Brent group.
The oil zones in the two wells are likely to be in communication, and both have been subject to extensive data gathering and coring, the company said.
Well 13 A reached a TVD of 3,108 m subsea and terminated in the Statfjord formation. Well 13 S reached a TVD of 3,258 m subsea and ended in the Hegre group.
StatoilHydro used the Scarabeo 5 semisubmersible rig to drill the wells in 381 m of water. The rig has moved to PL 199 for a workover of production well 6406/2-S-4 H.
Both wells have been plugged and abandoned.
Operator StatoilHydro has 59.06% of PL 120, where its partners are Petoro with 16.94%, ConocoPhillips 13%, and Total E&P Norge 11%.
