Side-track Success for Lundin at Johan Sverdrup

Sweden's Lundin Petroleum reported Monday that its wholly-owned subsidiary Lundin Norway has successfully completed the well 16/2-13A – the side-track of the Johan Sverdrup appraisal well 16/2-13S.

Lundin described the results of the well as "excellent" with respect to reservoir quality and thickness – validating the field geological model and confirming a deeper oil-water contact.

Well 16/2-13S was drilled approximately 1.5 miles northeast of the discovery well 16/2-6 and the side-track well 16/2-13A was drilled less than a mile to the north north-west. The Johan Sverdrup is located in licenses PL501 and PL265 on the Norwegian Continental Shelf.

The side-track well found a gross reservoir column of approximately 70 feet, of which a section of around 40 feet was above the oil-water contact. The top of the reservoir was around 15 feet shallower than the prognosis, while the oil-water contact was established approximately 6,315 below mean sea level (approximately 10 feet deeper than observed in earlier PL501 wells).

In a company statement, Lundin CEO Ashley Heppenstall said:

"The results from the latest appraisal well are positive. The Johan Sverdrup reservoir quality, as in previous wells, was excellent. However, we are particularly pleased that the side-track was not only shallow to prognosis but also encountered a lower oil water contact. We will now drill our next appraisal well to the north west to test the extent of the field in this area."

According to the Norwegian Petroleum Directorate, the wells were drilled by the Transocean Arctic (mid-water semisub) drilling facility which will now proceed to production license 490 to drill wildcat well 7120/6-3 S, where Lundin Norway is also the operator.
