OKEA spudded its first operated exploratory well on 16 October 2019 using the newbuild âDeepsea Nordkappâ S/S. 6407/9-12 is located on the Skumnisse prospect but is classified by the NPD as a Draugen appraisal. The well is located in PL 093 D approximately 4 km east of Draugen and the company hoped that it would identify new volumes in the area which could have helped in extending the fieldâs life into the 2040s. The main target was the Upper Jurassic Rogn Formation, prognosed at 1,658 m. A 12-1/4" pilot hole was drilled to around 1,050 m and the 20 x 9-5/8" casing was set before the well was suspended (around 18 October 2019) whilst the rig was used for the company's Infill O well (see separate article). On 1 November 2019 Skumnisse was re-entered and the reservoir section was drilled and cored. TD was reached at 1,775 m in the Middle Jurassic Garn Formation. The Rogn Formation (45 m thick) had only thin, poor quality clay-rich sandstones (totalling 15 m) and the well was abandoned as a dry hole on 8 November 2019.   OKEA gained its interest in PL 093 in late 2018 by way of a deal with previous operator Shell. The deal covered both Draugen and Gjoa (a 12% non-operated interest) and consisted of an initial consideration of USD 526 million (NOK 4.52 billion) with Shell retaining an 80% liability for the total decommissioning costs up to an agreed limit of USD 74 million after tax (NOK 638 million). OKEA will be responsible for the remaining liability. Decommissioning costs for the two assets are estimated to be around USD 120 million after tax (NOK 1 billion). Once OKEA has completed the decommissioning Shell will pay an additional USD 43 million (NOK 375 million) to OKEA. The deal increased OKEAâs net reserves to 53 MMboe.   Draugenâs main reservoir is the Rogn Formation at around 1,600 m. It also produces from the Middle Jurassic Garn Formation. OKEA believes that there are a number of follow-up targets which it will investigate in the coming years.  Interest in PL 093 D is divided between OKEA ASA (44.56% + operator), Petoro AS (47.88%) and Neptune E&P Norge AS (7.56%).
6407/09-12 (Skumnisse) appr. (Okea 44,56% op, Petoro 47,88%, Neptune 7,56%) in PL 093 D P&A dry at TD=1775m, Target Upper Jurassic Rogn Fm. Well confirmed the presence of a number of clay-rich sst. layers in the expected reservoir interval, but these were thinner and with poorer reservoir quality than expected, with no traces of hc observed.
