Lundin Petroleum AB, Stockholm, said its Norwegian affiliate has completed the Johan Sverdrup 16/3-7 appraisal well in the southeastern part of PL501 offshore Norway.
The well encountered 50 m of gross reservoir slightly deeper than expected. The reservoir consists of 14 m of excellent quality sandstone of late Jurassic age and 36 m of dolomitic carbonates of Permian age with good reservoir properties.
The 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, but oil and water were sampled in the uppermost part of the reservoir, at 1,925 m 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. Total depth is 2,075 m.
The wellsite is at the southeastern flank of the Johan Sverdrup discovery 3 km southeast of the 16/3-5 well and 4 km southwest of the 16/3-2 exploratory well.
The Bredford Dolphin semisubmersible will now drill the 16/5-5 appraisal well in PL410, also operated by Lundin Norway.
PL501 interests are Lundin Norway AS and Statoil Petroleum AS 40% each and Maersk Oil Norway AS 20%.
