Ardent Oil is looking to farm-out part of its interest in licence 11/16 (blocks 5604/27c, 5604/28a, 5604/31b and 5604/32) containing the Jarnsaxa prospect. Mean recoverable prospective resources are estimated at 130 MMbo. The licence was awarded in the 7th Danish Licensing Round in April 2016. The licence is for a six year term split into four phases. Phase 1 (2016-2018) requires data reprocessing and technical studies to be completed followed by a drill or drop decision. Phase 2 (2019) involves drilling one exploration well to evaluate the Pre-Cambrian basement with phase 3 (2020-2021) committing to drill a second exploration well or to relinquish the licence. Phase 4 (2022) will require the second exploration well to be drilled. The data used to define Jarnsaxa consists of the PGS Broadband Geostreamer (323 km sq), Danish Megasurvey (11,180 km sq) and legacy 2D data. Well studies included relevant source rock penetrations and offshore Palaeozoic penetrations from nearby wells.   The Jarnsaxa structure is a thrust-fault bounded anticline deformed by later faulting episodes. Pre-Cambrian fractured basement form the reservoir objective. The basement was subject to multiple tectonic phases of contraction, strike-slip and extension. The basement would have likely been exposed subaerially and any leach zone at the basement unconformity would enhance fractured reservoir effectiveness. Late Jurassic Kimmeridge Clay equivalent source rocks in the Tail End Graben charge nearby producing fields and could source Jarnsaxa. The Stork-1 well penetrated the source rock ~5 km from the acreage and is thought to be stratigraphically placed against the fault systems bounding Jarnsaxa. Carboniferous strata from a deep Palaeozoic sediment filled basin to the south could also charge the prospect. Seals from overlying Palaeozoic sediment was penetrated by offset wells and is interpreted to be tight clastic and volcaniclastic sediment. Further seal potential in the typically tight Late Cretaceous pelagic chalk units over lie the Permian clastics. The depth to the crest of the structure is 2,575 m subsea. The main risks consist of fractured basement reservoir and seal effectiveness.   Interest in 11/16 is held by Ardent Oil (Denmark) SA (80% + operator) and Danish North Sea Fund (20%).
