Lundin Petroleum has completed its appraisal well off the flank of the Edvard Grieg field.
The well was drilled 3 km west of the Edvard Grieg platform and was targeting additional resources.
It was also drilled to appraise the southwestern flank of the field in order to optimise the drainage strategy and to prove additional resources.
A report read: “The well encountered a 15 metres gross oil column in a 94 metres thick sandstone reservoir compared to the pre-drill estimate of 38 metres thickness. The top reservoir was encountered deeper than prognosed with excellent reservoir quality that was better than expected. The oil water contact was encountered at 1,948 metres below mean sea level 9 metres deeper than the established contact in this part of the Edvard Grieg field. Pressure data confirms communication with the Edvard Grieg field.”
The well results confirm a preliminary resource upside for this part of the Edvard Grieg field in the order of 10 to 30 MMboe. The final implication for total reserves for the Edvard Grieg field will be confirmed in the 2017 year end reserves update.
The well was drilled using the semi-submersible drilling rig Island Innovator and will be permanently plugged and abandoned.
The Edvard Grieg field is located in the Utsira High area in the central North Sea. The Utsira High area is Lundin Norway’s main focus area with the majority of Lundin Norway’s 2P reserves and contingent resources situated in this area.
Since making the Edvard Grieg discovery in 2007, Lundin Norway has made five additional discoveries in the Utsira High area with Apollo, Tellus, Luno South, Luno II and the giant Johan Sverdrup discoveries.
The Edvard Grieg reservoir is situated at a depth of approximately 1,900 metres, and consists of alluvial, eolian and shallow marine conglomerates and sandstones from the Triassic to Lower Cretaceous ages.
The field’s gross 2P reserves are estimated at 187 million of barrels of oil equivalents, boe (29.5 million Sm³ of oil equivalents).
