* Well encountered 30 metre oil column
* Well had "very high" reservoir quality in entire interval
OSLO Nov 6 Tests on the giant Johan Sverdrup
oil field in the Norwegian North Sea are "very good" and show
very high reservoir quality, licence partner Det norske
said on Tuesday.
An appraisal well, the ninth in the license, encountered an
oil column of approximately 30 meters in Upper Jurassic
reservoir rocks of very high reservoir quality, Det norske said
in a statement.
Johan Sverdrup was one of the world's biggest oil
discoveries last year and could hold up to 3.3 billion barrels
of recoverable oil in relatively shallow waters.
"Det Norske oljeselskap ASA is of the opinion that the well
results are every good," the firm said in a statement. "The
results will eliminate the uncertainty pertaining to the
reservoir quality of the northern part of central Johan
Statoil earlier said it would provide an updated resource
estimate sometime in the first quarter of 2013.
Johan Sverdrup lies in two licenses with Statoil and Lundin
Petroleum operating the two halves.
In production license 265, Statoil holds a 40 percent stake,
with other owners including state holding firm Petoro (30
percent), Det norske (20 percent) and Lundin (10 percent).
In license 501 Statoil and Lundin both hold 40 percent and
Maersk has 20 percent.
