Development

Edvard Grieg is a field in the Utsira High area in the central North Sea, 35 kilometres south of the Grane and Balder fields. The water depth is 110 metres. Edvard Grieg was discovered in 2007, and the plan for development and operation (PDO) was approved in 2012. The field is developed with a fixed installation with a steel jacket and full process facility, and it utilises a jack-up rig for drilling and completion of wells. The production started in 2015. The Edvard Grieg installation supplies power to the Ivar Aasen field and processes the well stream from Ivar Aasen. The Solveig field is tied-back to Edvard Grieg. The Troldhaugen discovery is temporarily tied-back to Edvard Grieg for test production.

Reservoir

Edvard Grieg produces undersaturated oil from alluvial, aeolian and shallow marine sandstone and conglomerate of Late Triassic to Early Cretaceous age. The reservoir is at a depth of 1900 metres. The eservoir quality varies from moderate to very good in marine and aeolian sandstone, while the quality is poorer in alluvial sandstone and conglomerate. Oil is also proven in the underlying basement.

Recovery strategy

The field is produced by pressure support from water injection.

Transport

The oil is exported by pipeline to the Grane Oil Pipeline, which is connected to the Sture terminal. The gas is exported in a separate pipeline to the Scottish Area Gas Evacuation (SAGE) system in the UK.

Status

Edvard Grieg production went off plateau in 2023. The field has been producing better than expected and the recoverable volumes have increased significantly since the PDO due to excellent reservoir performance. Two infill campaigns were finished in 2021 and 2023. Test production from the Troldhaugen discovery started in 2021 and has continued in 2023.
