A/S Norske Shell, operator of the Ormen Lange field, has completed the drilling of appraisal well 6305/4-2 S on the Ormen Lange field.
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 in 800-1100 metres of water in the southern part of the Norwegian Sea, about 130 kilometres northwest of Kristiansund. The well was drilled about 12 kilometres northwest of the field’s main production area.
The purpose of well 6305/4-2 S in production license 209 was to delineate the most northern extent of the field. The well encountered reservoir rocks of variable quality in both the Egga reservoir unit and the Jorsalfare Formation, but the well was dry.
Extensive data acquisition and sampling have been carried out. The result of this appraisal well will be incorporated into the ongoing evaluation of the Ormen Lange field, but will not result in changes to the assumed recoverable volumes for Ormen Lange.
Well 6305/4-2 S is the eight exploration well to be drilled on the Ormen Lange field. The appraisal well was drilled to a vertical depth of 2869 metres below the sea surface, and was terminated in the Kyrre formation in the Upper Cretaceous. The water depth at the site is 1086 metres. The well has been permanently plugged and abandoned.
The well was drilled by the drilling ship West Navigator(image), which will continue drilling production wells on the Ormen Lange field.
