Dry well on Heimdalshø

Dry well on Heimdalshø

Det norske oljeselskap ASA, as operator of production license 494, has

completed the drilling of wildcat well 2/9-5S. The well was drilled

about 30 km east of the Valhall field on the Heimdalshø prospect.

2/9-5S was the first well to test a new play concept in the Mandal High

area, where Johan Sverdrup and Utsira High is the analogue.

The purpose of the well was to prove petroleum in Upper Jurassic

reservoir rocks and secondary to prove sandstones with hydrocarbons in

the pre-Jurassic rocks.

The well encountered a few thin sandstones with reservoir quality in the

main target and only few and thin sandstones in the secondary target. No

traces of hydrocarbons were proven.

2/9-5S is the first exploration well in production license 494, awarded

in the APA 2008. The well was drilled to a vertical depth of 3,525.5

meters below sea level (3,587 meters MD RKB) and was completed in rocks

expected to be of Permian age. The water depth is 65 meters. The well

will now be permanently plugged and abandoned.

Well 2/9-5S was drilled by the drilling rig Maersk Giant, which will now

go to the Yme field operated by Talisman.

Det norske oljeselskap ASA is the operator of the license with a 30

percent working interest. Other partners are Dana Petroleum with 24

percent, Fortis Petroleum with 16 percent, Spike Exploration with 15

percent and Tullow Oil with 15 percent.
