Lille John-2 appraisal well encounters oil in the Danish North Sea
As operator of licence 12/06 Dana Petroleum Denmark B.V. has drilled the Lille John-2 (5504/20-06) appraisal well in the southern part of the Danish North Sea. The well confirmed the presence of oil in Miocene sandstones in the Lille John structure.
In 2011 the Licensee in licence 12/06 drilled the Lille John-1 exploration well and made the Lille John oil discovery in sandstones of Miocene age. The Lille John-2 appraisal well and a side-track, Lille John-2A, were drilled in order to further evaluate the extent of the discovery.
Lille John-2 was drilled as a vertical well and reached its total depth 1344 meters below mean sea level in clay stones of Miocene age. Cores were taken and a comprehensive logging programme was carried out. During a production test oil and gas was produced. Subsequently a deviated side-track was drilled.
The results of the well will now be evaluated by the companies in order to assess if the oil discovery can be produced commercially.
Lille John-2 was spudded on 12 December 2014 with the jack-up rig Paragon C20052 at the position 55° 25’ 11.309” N, 04° 50’ 08.648” E (UTM zone 31; 6,143,176 m N; 616,199 m E), where the water depth is 44.2 metres.
