DNO ASA - Drilling result of well 24/9-8, the Lie prospect in PL305

Well 24/9-8 was drilled into the reservoir section to TD at 2165 m below sea level. Hydrocarbons were not encountered and the well will now be plugged and abandoned. Through a transaction reported 19 January 2006, all well related costs for the Company's share will be paid by PA Resources.
This was the first well to be drilled by the Bredford Dolphin rig in the three year drilling contract the Company and six other operators in a consortium have with Dolphin. The rig will drill one well for another operator prior to returning to Det Norske Oljeselskap ASA to drill well 24/12-5S, the Thorkildsen prospect in PL341. The Company's share of the well related costs for the Thorkildsen well will also be paid by PA Resources.
The licensees in PL305 are Det Norske Oljeselskap ASA (30%), Revus Energy ASA (30%), Talisman Energy Norge AS (30%) and PA Resources Norway AS (10%).
