Det norske has successfully completed a production test on the Draupne discovery, where the company holds a 35% interest.
The production test was carried out using the Songa Delta drilling rig (picture). A limited part of the total hydrocarbon column in the vertical appraisal well was perforated. During the test, it produced between 1,100 and 3,300 barrels of oil per day through a choke with an opening of between 28/64 and 60/64 inches.
The oil was light and of good quality. Based on the results, Det norske believes that production wells in the field can yield good production rates, with an average production of about 12,000 barrels per day per well.
The production test in appraisal well 16/1-11 was Det norske’s first production test and as such an important milestone for the company. It provides a good basis for production testing in future exploration and appraisal wells operated by Det norske.
Draupne was discovered in 2008, and a total hydrocarbon column of 44 metres was encountered in the discovery well. Appraisal well 16/1-11 proved a hydrocarbon column of 57 metres. It has now been decided to drill a side track to determine the oil-water contact in the field. The test is a major step in the right direction for a commercialisation of Draupne, but further analysis of the results, as well as the information from the upcoming side track well, is necessary before an investment decision can be made.

In addition to the appraisal well on Draupne, Det norske is currently involved in another four well operations on the Norwegian continental shelf, including in PL 337, Storkollen, where Det norske is operator and has an ownership interest of 45%.
