Operator Lundin has hit oil on the Edvard Grieg field in the central North Sea.
The firm’s Norwegian arm drilled the appraisal well 3km southwest of the field’s namesake platform.
The Island Innovator drilling facility found a 15 metre column of oil in Cretaceous and Triassic/Jurassic sandstone with “very good” reservoir quality.
Before the well was drilled, the operator’s resource estimate for the field was 35 million standard cubic metres (Sm3) of recoverable oil equivalents.
Lundin said: “The objective of the well was to investigate the scope of the field, its reservoir properties and total oil column in the southwestern part of the Edvard Grieg field.
“The objective also included optimising the drainage strategy in order to ensure the best possible placement of development wells in this area.
“Preliminary calculations shows that the results from the well can lead to an increase of between 1.6 to 4.8 million standard cubic metres (Sm3) of recoverable oil in this part of the Edvard Grieg field.
“Further work is expected to reduce the uncertainty in this estimate. The results have provided valuable information with regard to final placement of production and water injection wells.”
This was the 11th exploration well in production licence 338 and the eighth exploration well on Edvard Grieg.
The appraisal well was drilled to a vertical depth of 2229 metres below the sea surface and terminated in granitic basement. The well has been permanently plugged and abandoned.
Lundin acheived first production from the field in 2015. Read more here.
