Sweden's Lundin Petroleum reported Wednesday that it has successfully completed and tested appraisal well 16/3-5 on the Johan Sverdrup discovery in production license 501, offshore Norway.
The well – located within a couple of miles of both appraisal well 16/3-4 and well 16/2-7 – encountered an approximately 100-foot gross oil column in an Upper Jurassic sandstone sequence and a Permian Zechstein Group carbonate reservoir, said Lundin. The firm also reported a comprehensive logging and coring program has been completed as well as two production tests – with the first test (in the Zechstein carbonate) resulting in low flow rates and the second test (in the Upper Jurassic sandstone) resulting in a flow rate of 4,700 barrels of oil per day.
Lundin CEO Ashley Heppenstall commented in a statement:
"We are extremely pleased with the test results from this latest appraisal well which in terms of reservoir quality… represents one of the best tests ever seen in the North Sea. The Zechstein carbonate test indicates upside potential which will require further evaluation."
Well 16/3-5 will now be plugged and abandoned. Lundin is the operator of PL 501, with a 40-percent interest. Statoil also holds 40 percent of the license, while Maersk Oil Norway has 20 percent.
The Bredford Dolphin (mid-water semisub) rig used to drill the well will now move to PL359 to drill the Luno II exploration prospect that is also operated by Lundin.
