Lundin Petroleum discovered a 15m oil column at the Edvard Grieg Southwest appraisal well in the North Sea, confirming an upside for the field.

Lundin subsidiary Lundin Norway completed the 16/1-27 appraisal well in PL338, on the southwestern flank of the Edvard Grieg field, targeting additional resources.
The well was drilled 3km west of the Edvard Grieg platform with the Island Innovator semisubmersible.
Lundins says that the objective of the well was to appraise the southwestern flank of the field to optimize the drainage strategy and to prove additional resources. The well encountered a 15m gross oil column in a 94m thick sandstone reservoir compared to the pre-drill estimate of 38m thickness.
“The top reservoir was encountered deeper than prognosed with excellent reservoir quality that was better than expected,” says Lundin. “The oil water contact was encountered at 1948m below mean sea level 9m deeper than the established contact in this part of the Edvard Grieg field.”
The company says that pressure data confirms communication with the Edvard Grieg field.
Extensive data acquisition was carried out in the reservoir including conventional coring and fluid sampling.
“The well results confirm a preliminary resource upside for this part of the Edvard Grieg field in the order of 10-30 MMboe,” says Lundin.
Lundin will provide total reserves for the Edvard Grieg field at the end of the year.
The well will be permanently plugged and abandoned.
Lundin Norway is the operator of PL338 and holds a 65% working interest. The partners are OMV Norge (20%) and Wintershall Norge (15%).
