STAVANGER, Norway -- Norske Shell, operator of the Ormen Lange field, has completed drilling appraisal well 6305/5-3 S in production license 209 in the North Sea.
The objective was to delineate the northern extent of the field. The well encountered reservoir rocks of variable quality in the Egga reservoir unit and the Jorsalfare formation, the company reports. Gas encountered in Egga confirms pressure communication with the gas-producing area. Preliminary evaluations show gas/water contact in the Egga. The gas/water 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 was done.
The appraisal well results will be incorporated into a major re-interpretation of the field aimed at a better resource estimate, the company says. Parts of the field’s future development and long-term production profile may be affected by the new estimate, the company says.
The semisubmersible Leiv Eiriksson drilled the well to a vertical depth of 2,815 m (9,235 ft) below sea level. The well was terminated in the Kyrre formation in the Upper Cretaceous. The well has been temporarily abandoned.
