6305/5-3 S

30/10/2009 A/S Norske Shell, operator of the Ormen Lange field, has completed the drilling of appraisal well 6305/5-3 S in production licence 209 (on behalf of the Ormen Lange field licensees).

Ormen Lange was proven in 1997 and has been in production since 2007. The reservoir is in Paleocene and Upper Cretaceous reservoir rocks (Egga reservoir unit and the Jorsalfare formation). The field is situated about 130 km northwest of Kristiansund  in the southern part of the Norwegian Sea, and the water depth is 800-1100 metres.  The well was drilled six kilometres northeast of the field's main production area.

The objective of well 6305/5-3 S  in production licence 209 was to delineate the northern extent of the field. The well encountered reservoir rocks of variable quality in both the Egga reservoir unit and the Jorsalfare formation. Gas was encountered in Egga, and it was confirmed that there is pressure communication with the area from which gas is produced. Preliminary evaluations show gas-water contact in the Egga reservoir unit. The gas-water contact was encountered at a shallower level than in the main part of the field. The well was not formation-tested, but extensive data acquisition and sampling have been carried out.

The result of this appraisal well will be incorporated into a major re-interpretation of the field aimed at providing a better resource estimate. It is uncertain whether the original upside potential can be realised. Parts of the future field development and the long term production profile may be affected by the new estimate.

Well 6305/5-3 S is the seventh exploration well to be drilled on the Ormen Lange field. The appraisal well was drilled to a vertical depth of 2815 metres below sea-level, and was terminated in the Kyrre Formation in the Upper Cretaceous. The water depth is 832 metres. The well has been temporarily abandoned. The well was drilled by the semi-submersible drilling facility Leiv Eiriksson, which will now carry out drilling operations outside the Norwegian shelf.
