Ekofisk was Norway's first producing field and is also one of the largest on the Norwegian continental shelf. The reservoir is Cretacious (chalk) with a 300 meter high oil column. It covers an area of 10x5 kilometers, 3000 meters below sea level. It produces both oil and gas.

Production started in 1971. The Ekofisk South development project (2013) contributes to continued production towards 2050.​

Ekofisk 2/4 K-B

Ekofisk 2/4 K-B is located 2.3 kilometers north of the Ekofisk Complex. These two platforms have joint staffing and are connected with a gangway. Operations on the two platforms are controlled from the control room on Ekofisk 2/4 K.

 

Ekofisk 2/4 B

Ekofisk 2/4 B is a production platform for oil and gas with 24 wells. The oil and the gas from 2/4 B is transported by pipelines to the Ekofisk Complex. Personnel who work daily on this platform live on Ekofisk 2/4 K.​
 

Ekofisk 2/4 K

Ekofisk 2/4 K is a water injection and accommodation platform with 30 wells. The living quarters module has 182 beds on five floors, and both personnel working on this platform and on Ekofisk 2/4 B live here.
 
The water injection on Ekofisk started from Ekofisk 2/4 Kilo in 1987. From 1990, Ekofisk 2/4 K has supplied injection water to other platforms as well. From 2010, when the seabed unit Ekofisk 2/4 VA came on stream, water injection on the Ekofisk field has been done either from 2/4 K or from this new unit.
 
The daily injection rate into the Ekofisk reservoir is approximately 450,000 barrels of water. Part of this injection water is supplied from Eldfisk 2/7 E and transported in a 24-kilometer long pipeline to Ekofisk 2/4 K for injection from there.
 
The total daily injection rate on Ekofisk and Eldfisk is approximately 650,000 barrels of water.
 
Water injection is used to increase the recovery of oil and gas. The function of the water is to maintain reservoir pressure at a stable level as oil and gas is recovered from the reservoir. Water injection is the single most important factor in keeping the production on the Ekofisk field at a high level.​
