Johan Sverdrup Appraisal Well Successful

Sweden's Lundin Petroleum and the Norwegian Petroleum Directorate (NPD) announced Friday that the 16/2-16AT2 appraisal well on the Johan Sverdrup discovery on production license 501 has been successfully completed.

The well was drilled as a side track to well 16/2-16 on the northeastern flank of the Johan Sverdrup field – approximately 0.6 miles to the west of the main bore hole. The objective of the side track was to improve the understanding of the lateral variations in reservoir qualities and relations to oil-water contacts in the neighboring wells.

Lundin (the operator, with a 40-percent interest) reported that the well encountered a gross oil column of approximately 98 feet with "largely excellent" reservoir quality within the Jurassic reservoir sequence. The acquired data also confirms an oil-water contact at approximately the same level as in well 16/2-10, which is the deepest observed at Johan Sverdrup.

"We are very pleased with the results of the latest appraisal well which has encountered excellent reservoir as well as confirming the deep oil water contact at this location," Lundin CEO Ashley Heppenstall commented in a company statement.

According to the NPD, the 16/2-16 and 16/2-16A appraisal wells were drilling into Permian and Triassic rocks, with vertical depths of 7,175 feet and 6,760 feet respectively. These wells will now be permanently plugged and abandoned, while the Transocean Winner (DW semisub) rig that drilled them will proceed to production license 388 to drill wildcat well 16/1-17 – where Lundin is also the operator.
