Lundin Petroleum’s subsidiary Lundin Norway has completed the Rolvsnes exploration well 16/1-25 S in the Norwegian North Sea as an oil discovery, according to a news release.

The well, located south of the Edvard Grieg Field, encountered a gross oil column of 30 m 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, Lundin said in the news release. Extensive data acquisition and sampling were carried out in the reservoir including conventional coring and fluid sampling.

A production test was performed, achieving a production rate of 265 barrels of oil per day (bbl/d) through a 36/64-in. choke, the release said.

Lundin said 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.

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), Lundin said in the release. Significant resource upside remain, including the 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, according to Lundin.

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.
