Norske Shell found a 28-m gas column with an appraisal well in Ormen Lange field, the Norwegian Petroleum Directorate reported.
The gas column and an underlying 70-m water zone are in the Vale formation’s Egga reservoir unit, NPD said.
The objective of well 6305/8-2, drilled in the southern Norwegian Sea, was to delineate the field to the south.
The well was drilled to a vertical depth of 3,038 m subsea and was terminated in the Kyrre formation in Upper Cretaceous. Water depth is 615 m. The well is about 7 km south-southeast of the southernmost subsea template on the field.
Well 6305/8-2 was drilled in production license 250 by Transocean Ltd.’s Transocean Barents semisubmersible drilling rig, which will move to Draugen field to permanently plug production well 6407/9-A-53-H in PL 093.
NPD said the results of extensive data acquisition and sampling do not provide a basis for changing the expected recoverable reserves from Ormen Lange (OGJ Online, Nov. 30, 2007). Ormen Lange was proven in 1997 and has been producing since 2007.
