On 7 February 2018 Lundin spudded Luno II appraisal well 16/4-11 in PL 359 with the âCOSL Innovatorâ S/S. 16/4-11 is located in the southerly part of the field in the central section (segment B), approximately 2 km southeast of the discovery well. The well was terminated in Triassic or Permian rocks at 2,450 m TVDSS and encountered a 20 m oil column in Triassic sandstones. Reservoir quality is good to very good and the OWC was encountered at approximately 1,947 m subsea. The reservoir (including the water zone) has a total thickness of around 400 m comprising mainly sandstone with some layers of conglomeratic sandstone. Estimated recoverable reserves are between 31 â 82 MMbo and 35 â 106 Bcfg. On 26 March 2018 the well was being abandoned.  The licensees will now begin development planning for the discovery with PDO submission likely at the end of 2018. If development of Luno II goes ahead it would be a phased tie-back to Edvard Grieg. Phase I would focus on segment B and would include four wells and then future phases would cover segments A (southeast) and C (northwest) plus any additional prospectivity (segment D and Fignon to the northwest and Back Basin to the north) that is proved to be successful.   Luno II discovery well 16/4-6 S was drilled in 2013. A 280 m Jurassic / Triassic sandstone with high net to gross was encountered containing a 45 m gross oil column. The oil is light, the OWC is at 1,950 m and there is a thin gas cap. The well flowed at a rate of over 2,000 bo/d through a 48/64â choke. Later in 2013 Lundin drilled appraisal well 16/5-5 to test the potential southeasterly extension of Luno II. A 150 m thick fine-grained Triassic sandstone came in high to prognosis but was of poor quality. It was concluded that there is a pressure barrier between this well and the discovery well and that 16/5-5 lies in a separate sub-basin. A further appraisal well, 16/4-8 S, was drilled in 2014 and proved a 500 m thick sandstone in the Jurassic / Triassic with a 30 m oil column lying below a very thin gas zone. The well flowed at a rate of 450 bo/d through a 28/64â choke. Estimated recoverable reserves for Luno II are 27-71 MMboe (79% oil).  In 2015 Lundin made a small light oil discovery with exploration well 16/4-9 S drilled on the Luno II North prospect. A gross oil column of 23 m was proven in conglomeratic sandstones of the Jurassic / Triassic in a separate sub-basin to the northwest of Luno II. The pressure regimes are different in Luno II and Luno II North and the OWC for Luno II North is deeper at 1,954 m subsea. The well was tested and flowed at a rate of 1,000 bo/d through a 32/64â choke. Estimated recoverable reserves are 12-26 MMboe and it is likely that Luno II and Luno II North will be developed together as a subsea tieback to Edvard Grieg.   Interest in PL 359 is divided between Lundin Norway AS (50% + operator), OMV (Norge) AS (20%), Statoil Petroleum AS (15%) and Wintershall Norge AS (15%).  Â   Â
