Maersk Interceptor completes Ivar Aasen pilot well campaign
The jackup Maersk Interceptor has completed drilling two geo pilot wells on the Ivar Aasen field in the central Norwegian North Sea for operator Det norske oljeselskap.
Det norske says the program should increase its understanding of the reservoir and will provide insights into the optimal location of production and injection wells.
The main aims of wells 16/1-21 S and 16/1-21 A were to investigate reservoir rocks and reservoir quality, and the extension of an overlying gas cap in the eastern part of the field.
Well 16/1-21 S encountered a 54-m (177-ft) oil column, including 25 m (82 ft) of good-quality reservoir in the Skagerrak formation, but no gas. In the Heimdal formation, the well intersected 27 m (88.6 ft) of water-filled sandstone, also of good quality.
16/1-21 A encountered a 41-m (134.5-ft) oil column and a 4-m (13-ft) gas column, with a total of 29 m (95 ft) of high-quality reservoir in the Sleipner and Skagerrak formations. The well did not find the oil/water contact.
These wells were the first drilled by the new jackup, claimed to be the world’s largest, which arrived in Norway last October.
Det norske has contracted the rig for five years, with an option for two more. After drilling an appraisal well in the western part of the field the rig is assigned to drill 15 development wells, comprising eight producers and seven water injectors.
