Lundin reported Thursday that it has completed Johan Sverdrup field appraisal well 16/3-7, which encountered a 164-foot reservoir that included 46 feet of "excellent-quality" sandstone of late Jurassic age as well as 118 feet of dolomitic carbonates of Permian age with good reservoir properties.
Lundin said the North Sea well showed a good common water gradient in both the sandstone and carbonates demonstrating good communication between the two reservoirs. The oil-water contact was not proven in the well. However, oil and water was sampled in the uppermost part of the reservoir, at 6,315 feet below mean sea level, which indicates an oil-water contact close to this level and that the well was positioned near the edge of the field.
The firm added that the well was drilled to a total depth of approximately 6,810 feet below mean sea level into sediments of Permian age. A comprehensive coring and logging program has been successfully completed, it said.
The well was drilled using the Bredford Dolphin (mid-water semisub). The rig will now drill appraisal well 16/5-5 in PL410, also operated by Lundin Norway.
Lundin Norway is the operator in PL501 with 40-percent interest. The partners are Statoil, with 40-percent interest, and Maersk Oil Norway, which has a 20-percent interest.
