EquinorÂ used the âTransocean Spitsbergenâ S/S to drill exploration wellÂ 16/5-7Â on theÂ KlaffÂ prospect which was spudded 12 June 2019 (delayed from 2018). The well is located inÂ PL 502, immediately southwest of Johan Sverdrup. It had objectives in the Jurassic, Triassic and Permian and partner Aker BP reported prospective, pre-drill, resources of 50-372 MMboe. 16/5-7 was drilled to TD at 2,028 m in Basement and on 12 July 2019 it was abandoned. No reservoir intervals were encountered at any level, although oil shows were observed in the upper 19 m of the weathered and fractured Basement (possibly residual). The well is classified as a dry hole.    The first phase of Johan Sverdrup is due onstream in November 2019. Development will concentrate on the Field Centre (in the north-west area of the field, PL 265) and will consist of four bridge-linked fixed platforms (WHP plus drilling, processing, riser/utility and accommodation) plus three subsea water injection templates. A total of 35 wells are planned for Phase I. The PDO for Phase II was submitted in August 2018 with a planned onstream date of Q4 2022. Phase II will include a new processing platform added to the Field Centre facilities, increasing processing capacity to 660,000 boe/d. There will be five subsea templates hosting 28 new wells and the establishment of the power-from-shore solution for the whole Utsira High area by 2022. In August 2018 recoverable reserves for Johan Sverdrup were increased to 2.2 - 3.2 Bboe.    Equinor Energy AS operates PL 502 with a 44.44% interest. Petoro AS holds 33.33% and Aker BP ASA holds the remaining 22.22%.
016/05-07 (Klaff) nfw (Equinor 44,44% op, Petoro 33,33%, Aker BP 22,22%) in PL 502, SW of Johan Sverdrup, P&A, dry,  intersected about 110m of basement rock. It noted that roughly 77m of this was weathered and fractured basement rock with poor to moderate reservoir properties. While the well did encounter traces of oil in a 19m zone in the upper part of the basement, it was impossible to determine whether the oil was producible or simply residual. Along with the basement rock, the well was also drilled to investigate potential reservoir rocks in several other levels including the Upper Jurassic intra Draupne formation sst, Upper Triassic Skagerrak Fm. and Upper Permian Zechstein group. TD=2028m.
