Oil and gas exploration and production company Lundin Petroleum has commenced the drilling of appraisal well 16/3-8S on the Johan Sverdrup discovery, located in the North Sea sector of the Norwegian Continental Shelf (NCS).
The Sweden-based company made the announcement through its wholly-owned subsidiary Lundin Norway.
Located on PL501 at the crest of the Avaldsnes High in the eastern part of the discovery, the well is expected to provide information of the Zechstein group carbonates sub-cropping the Jurassic reservoir in the Avaldsnes High area of the Johan Sverdrup discovery.
The well will establish the depth, quality and thickness of Zechstein group carbonates of Permian age, and also investigate the presence and quality of Jurassic reservoir sequences about 3.9km south-east of the discovery well 16/2-6.
According to the company, the carbonates may play a vital role for the development of this part of the discovery as a potential good oil reservoir, as well as optimise the production planning of the Jurassic oil reservoir directly on top of it.
The planned total depth of the well is said to be about 2,025m below the mean sea level.
The well will be drilled using the semi-submersible drilling rig Bredford Dolphin, and the operation is expected to take about 45 days.
Lundin Petroleum operates PL501 with 40% interest and the partners include Statoil Petroleum with 40% interest and Maersk Oil Norway with 20% interest.
With a balanced portfolio of assets primarily located in Europe and South East Asia, the company has proven and probable reserves of 202 million barrels of oil equivalent.
