The Rolvsnes exploration well 16/1-25 S, 6 km south of Edvard Grieg field, encountered a gross 30-m oil column in porous granitic basement in PL338C, which is operated by Lundin Petroleum AB’s subsidiary Lundin Norway AS.
The new well is located in the central North Sea, 3 km south of Lundin’s earlier Edvard Grieg South discovery made in 2009. The well lies on the southwestern flank of the Utsira High. Pressure data and oil type indicate that the petroleum system is in communication with the original discovery. Production tests achieved 265 bo/d through a 36/64-in. choke. The operator is planning further study to prove potential for an extended reach well from the Edvard Grieg platform.
Gross contingent resources for Rolvsnes, including the Edvard Grieg South discovery, is estimated at 3-16 million boe. Upside potential for prospect is 10-46 million boe, Lundin said in a press release.
Exploration well 16/1-25 S is the second well drilled in PL338C, which was carved out from PL338 in late 2014 (OGJ Online, Feb. 24, 2015). Well 16/1-25 S was drilled to a total depth of 2,096 m below mean sea level in 106 m of water. The Bredford Dolphin semisubmersible drilled the well, which will now be permanently plugged and abandoned.
Lundin Norway is operator of PL338C with 50% working interest. Partners include Lime Petroleum Norway and OMV (Norge) AS with 30% and 20% working interest, respectively.
Lundin started oil production on Nov. 28, 2015, from Edvard Grieg field in PL338 (OGJ Online, Nov. 30, 2015).
