DONG Makes Discovery on Siri Field

DONG has completed the appraisal well Siri-5/5A (5604/20-8) at the Siri Field in the North Sea. The well was drilled with the jackup, Maersk Gallant in the part of the Siri Field referred to as Stine Segment 2.

The well was spudded November 21, 2002 in approximately 193 feet of water.

Siri-5 was drilled in the southern part of Stine Segment 2. The well reached total depth at 2108 meters below sea level and finalized in the Vale Formation just above the Chalk. Siri-5 confirmed the expectations to the presence of oil in the Paleocene sandstone reservoir in the southern part of the Stine Segment 2 area. Subsequently a deviated side-track, Siri-5A, was carried out in order to acquire further information about the reservoir and the extent of the oil accumulation.

The well has now been plugged and abandoned and the drilling unit has been moved into the Norwegian sector.

Production from Stine Segment 2 was established in the autumn of 2001 through a horizontal well from the Siri platform. Based on the results from Siri-5/5A the oil companies plan to drill a further horizontal producer from the Siri platform to the southern part of Stine Segment 2. The well will be spudded within 1-11/2 months, when Maersk Gallant returns to the Danish sector.

The 6/95-licence group consists of the following companies: DONG as operator with 50%; Paladin Oil Denmark Limited with 30%; and DENERCO with the remaining 20%.
