Johan Sverdrup Jurassic oil test 'best in North Sea'

The result from the latest appraisal well in the Johan Sverdrup area offshore Norway “in terms of reservoir quality of the Volgian reservoir represents one of the best tests ever seen in the North Sea,” said Lundin Petroleum AB, Stockholm.

Lundin Petroleum’s Norwegian subsidiary is operator of the Johan Sverdrup discovery.

The 16/3-5 well went to a total depth of 2,025 m below mean sea level in PL501 about 3 km south of the 16/3-4 appraisal well and 3 km east of the 16/2-7 appraisal well. Well 16/3-5 found a 30-m gross oil column, shallow to depth prognosis, consisting of a 14-m Upper Jurassic sandstone of excellent quality above a 16-m oil column in a Permian Zechstein Group carbonate of varying reservoir quality.

A drillstem test in the Upper Jurassic sandstone sequence flowed at a rate of more than 4,700 b/d of oil on a 48/64-in. choke. The test showed exceptional flow properties, better than estimated from log evaluations, the company said. DST analysis indicates a laterally continuous reservoir without flow barriers.

The Zechstein carbonate DST resulted in low flow rates, but logs, core, and losses while drilling are indicating upside potential for better flow properties in the Zechstein sequence, the company said.

The company will plug the well and move the Bredford Dolphin semisubmersible to PL359 to drill the Lundin-operated Luno II exploration prospect.
