Lundin Norway AS, operator of production licence 501, is in the process of completing the drilling of appraisal wells 16/2-16 and 16/2-16 A in the North Sea.

The 16/2-6 Johan Sverdrup oil discovery was proven by Lundin in the autumn of 2010 in Upper Jurassic reservoir rocks in licence 501. Wells 16/2-16 and 16/2-16 A have been drilled approx. three kilometres northwest of the 16/2-6 discovery well and three kilometres east of the 16/2-10 appraisal well.

The purpose of appraisal well 16/2-16 was to investigate the reservoir properties, thickness and depth of the Upper Jurassic reservoir rocks, as well as to establish the oil/water contact in this part of the Johan Sverdrup discovery. The well encountered oil in the top metre of the reservoir, which consists of a 15-metre zone of Upper to Middle Jurassic reservoir rocks with medium to good reservoir quality. The total thickness of the entire interval from the Jurassic Age is 55 metres. The sandstone reservoir rocks are thinner than expected. Rocks from the Triassic and Permian ages and older were encountered under the oil-bearing layers. The carbonates from the Permian age in the Zechstein Group are of moderate to good reservoir quality.
