Lundin Petroleum AB, Stockholm, said the 16/2-11 Johan Sverdrup appraisal well in PL501 in the North Sea offshore Norway encountered a 54-m gross oil column in Upper and Middle Jurassic sandstone reservoir and will now be sidetracked eastward to probe lateral thickness and establish oil-water contacts.
The well, which encountered the reservoir at depth prognosis, will later be plugged and abandoned. Lundin Petroleum will delay the release of an updated resource estimate most likely until after completion of the 2012 drilling program.
The 16/2-11 well, total depth 2,125 m measured depth, is 2.2 km southeast of the 16/2-8 well in PL265 and 3.3 km southwest of the 16/2-6 well in PL501. The company performed a comprehensive logging and coring program and drillstem tested the previously untested Middle Jurassic reservoir. The data confirmed good reservoir properties and were in line with the predrill forecast.
The well flowed in excess of 2,700 b/d of oil through a 40/64-in. choke on the full scale production DST, and data indicate a laterally continuous reservoir.
After completing the sidetrack, the Bredford Dolphin semisubmersible will move to PL519 to drill the Lundin Petroleum-operated Albert exploration prospect.
