Sweden-based Lundin Petroleum said Wednesday that its exploration well 16/4-9 S made an oil discovery at the Luno II North prospect in the Norwegian North Sea.

Well 16/4-9 S is located on the southwestern flank of the Utsira High, 9.3 miles south of the Lundin Petroleum operated Edvard Grieg field and 2.4 miles northwest of the Luno II discovery well, 16/4-6 S.

The well is located in a separate sub-basin northwest of the Luno II discovery at PL359, in the central North Sea sector of the Norwegian Continental Shelf.

Well 16/4-9 S encountered a 75 foot gross oil column of “reasonable quality Jurassic/Triassic conglomeratic sandstones,” Lundin said.

Lundin said pressure data indicates that the petroleum system at the Luno II North discovery is different than the system observed in the Luno II discovery.

Extensive data acquisition and sampling was carried out in the reservoir, including conventional coring and fluid sampling.

One production test was performed in the oil zone, producing at a rate of 1,000 barrels of oil per day through a 32/64″ choke.

The gross contingent resource range for the Luno II North discovery, representing the southern part of the prospect, is estimated to be between 12 to 26 million barrels of oil equivalents.

The well was drilled to a total depth of 7,562 feet below mean sea level in a water depth of 328 feet.

“Whilst the analysis of the economic viability of the various development concepts is ongoing one possible development solution could be a combined Luno II and Luno II North subsea tie-back to the Edvard Grieg field,” Lundin said.

Both the Luno II North and the Luno II discoveries are located wholly in PL359 with a fully aligned ownership between PL359 and Edvard Grieg’s PL338.

The Luno II discovery is estimated to contain a gross contingent resource range of between 27 and 71 million barrels of oil equivalents.

Well 16/4-9 S was drilled using the semi-submersible drilling rig Bredford Dolphin.

The well will be permanently plugged and abandoned.

Lundin Norway  is the operator of PL359 with a 50 percent working interest.

OMV (Norge) holds a 20 percent working interest in the permit, Norway’s Statoil Petroleum holds a 15 percent working interest and Wintershall Norge holds a 15 percent working interest.
