Lundin strikes oil in Rolvsnes prospect (Norway)

Lundin Petroleum has completed the Rolvsnes exploration well 16/1-25 S, in the North Sea offshore Norway, as an oil discovery.

The well was spud in October 2015. It is located in PL338C south of the Edvard Grieg field in the central North Sea sector of the Norwegian Continental Shelf (NCS).

The well is on the southwestern flank of the Utsira High, approximately 6 km south of the Lundin Petroleum operated Edvard Grieg field and 3 km south of the Edvard Grieg South discovery.

According to Lundin, the well encountered a gross oil column of 30 metres in porous granitic basement. Pressure data and oil type indicate that the petroleum system is in communication with the Edvard Grieg South discovery which was made by Lundin Norway in 2009. Extensive data acquisition and sampling was carried out in the reservoir including conventional coring and fluid sampling, Lundin said.

A production test (DST) was performed, achieving a production rate of 265 barrels of oil per day through a 36/64″ choke. Further studies will be required to incorporate all the findings and establish future planning, such as the potential drilling of an extended reach well from the Edvard Grieg platform with an associated long-term production test, Lundin added.

The gross contingent resource range for Rolvsnes, based on natural depletion drive, including the Edvard Grieg South discovery is estimated to be between 3 and 16 million barrels of oil equivalents (MMboe). There remains significant resource upside including potential to find a more extensive fracture network and secondary recovery potential. Including this prospective upside potential the total gross resource estimate is between 10 and 46 MMboe.

Exploration well 16/1-25 S is the second well drilled in PL 338C, which was carved out from PL338 in late 2014. Well 16/1-25 S was drilled to a total depth of 2,096 metres below mean sea level in a water depth of 106 metres.

The well was drilled using the semi-submersible drilling rig Bredford Dolphin and will be permanently plugged and abandoned.

Lundin Norway is the operator of PL338C with 50 percent working interest. The partners are Lime Petroleum Norway with a 30 percent working interest and OMV (Norge) AS with 20 percent working interest.
