Dana Petroleum has completed drilling of the Lille John-2 appraisal well and side-track on the Lille John oil field in the Danish North Sea.
The appraisal well and side-track confirmed the presence of sweet, light oil in the Late Miocene sandstone reservoir.
The company said the thickness and quality of the sandstone reservoir encountered in LJ-2 was found, as expected, to be improved relative to the LJ-1 discovery well drilled in 2011.
Dana’s exploration director Dr Richard Fox said: “The results of the appraisal well and side-track are very encouraging demonstrating a healthy oil flow rate. The 12/06 licence is a great strategic fit for Dana giving us access to resources close to our existing licences operated from our Netherlands office, as we look to grow and develop our European operations.”
The entire reservoir package was cored and a comprehensive log suite gathered followed by a drill stem test over the entire interval.
Dana said the production test showed a maximum flow rate of 1,400 bbls/day, with no sand production.
The oil quality was similar to that found in the LJ-1, being 34°-35° API with no H2S.
A detailed evaluation of the acquired data will now be performed to confirm the thickness of the oil pay in order to assess the recoverable volumes in the Lille John accumulation and determine its commerciality.
The Danish exploration licence 12/06 also contains the Broder Tuck gas/ condensate discovery.
Dana acquired a 40% equity in the licence from PA Resources last year and assumed operatorship on June 1 2014.
The 12/06 licence is located near existing Dana operated licences in the Netherlands; the F02a production licence containing the Hanze oil field and Pliocene (shallow) gas field and the F06 exploration licence.
The following companies participate in License 12/06: Dana Petroleum Denmark B.V. (40% and operator), PA Resources (24%), Nordsøfonden (20%), Danoil Exploration A/S (8%) and Spyker Energy ApS (8%).
