Ekofisk 2/4 M was installed in the summer of 2005 south-east of Ekofisk 2/4 J and tied to the latter by a bridge. Aker Verdal built the jacket and bridge support, Aker Kværner Technology designed the jacket, and Kværner Egersund fabricated the module support frame and bridge.
The installation was constructed as part of the Ekofisk Area Growth project, which aimed to improve oil and gas recovery as well as to increase processing capacity and reliability from the Greater Ekofisk Area.
In addition to 30 well slots come a high-pressure separator, equipment for treating produced water, and risers for use in future projects. Processing capacity is 240 000 barrels of oil and 8.5 million standard cubic metres of gas per day. In addition, water treatment capacity is 150 000 daily barrels.
The platform does not have its own drilling rig, and wells are drilled by a chartered jack-up. However, arrangements are made for operations using coiled tubing – a long length of pipe reeled on a drum for use with well workovers and drilling.
Production from 2/4 M began on 23 October 2005, and petroleum and energy minister Odd Roger Enoksen performed the official inauguration on 9 January 2006.
