Statoil Heidrun Nordflanken

Statoil HEIDRUN Nordflanken

Norway Blocks 6507/7 and 6507/8

Landmark: Statoil's first field which can handle produced water without environmentally harmful discharges

Heidrun was discovered in 1985 by Conoco, which served as operator for the exploration and development phase. Statoil took over in 1995 as production operator. The north bank of Heidrun was brought onstream in August 2000, which helped maintain the plateau production for a further four years until 2004.

Oil from the field is primarily shipped by shuttle tanker to Statoil’s Mongstad crude oil terminal near Bergen for continued transport to customers. Gas from Heidrun is piped to Tjeldbergodden in mid-Norway and provides the feedstock for the Statoil methanol plant. From 2001, the field has also been tied to Åsgard Transport. Heidrun gas is piped through this trunkline to Kårstø, north of Stavanger and on to Dornum in Germany, a total distance of roughly 870 miles (1,400 km).

Heidrun has become the first Statoil field which can handle all produced water without any environmentally harmful discharges. The field partners have invested in a plant for the injection water. Any oil or chemical residues the outflow contains are injected back into the reservoir. Under normal operations, there are neither harmful discharges into the water nor additional emissions into the air. The injected water serves as pressure support to improve oil recovery.
