Ekofisk 2/4A - end of an era

After 39 years, Ekofisk 2/4A has been shut-down permanently and decommissioning work on the wells will start next year. The steel platform was built in France and produced 70,000 bbls per day at peak production and a total of 872 MMBOE. The last well to be shut-in, A20 produced 87 million barrels.

Originally the platform had a crew of 35 people but since 1996 it was remotely operated, first from the Ekofisk 2/4K control room, and latterly from the onshore operations centre in Tananger.

The Rowan Gorilla 6 drilling rig will plug and abandon the 23 wells and this work is expected to be complete in 2016.

Although the 2/4A platform is shut-in, production from the Ekofisk field continues from the other platforms and new wells continue to be drilled.
