LONDON, Nov. 21 -- DNO ASA estimates it has discovered 107 million bbl of oil in place in Paleocene rocks in its Storskrymten prospect in the Norwegian North Sea.

It estimates total recoverable volumes at 9-44 million bbl. DNO will assess production through the Petrojarl Varg floating production unit on Varg oil field 17 km south of Storskrymten.

Using the Maersk Giant jack up, the company drilled exploration well 15/12-18S and sidetrack 15/12-18A between Sleipner and Varg fields in 90 m of water. The exploration well reached 3,520 m TD in a Permian formation. The sidetrack was drilled to a TD of 3,036 m and was completed in late Cretaceous rocks.

DNO found oil in a Paleocene reservoir. Its exploration well targeted the Storskrymten prospect and the Grytkollen prospect assessing Jurassic-Triassic rocks.

"In the Paleocene, a 23 m oil column was discovered in sandstone with good reservoir properties and belonging to the Ty formation. A 9 m thick sand was penetrated in the Jurassic age (Grytkollen), but this was water-bearing," DNO said.

The sidetrack found the Heimdal sandstone reservoir to be oil-bearing. The well found sand in the Ty formation, DNO added. "Further analyses are necessary to determine if an appraisal well has to be drilled."

It will abandon the well before transferring the rig to Talisman. Licensees in Production License 337 are DNO with 45%, Dana Petroleum 25%, Revus Energy 20%, and Bridge Energy 10%.
