6506/11-11 S

Operations and results

Well 6506/11-11 S was entered with the semi-submersible Deepsea Bergen rig on 31 May 2019 and was drilled to TD at 4443 m (4432.7 m TVD) in the Early Jurassic Ror Formation. The well was drilled down to 469.5 m with seawater and high viscosity pills, from 469.5 to 1426 m with KCl Polymer mud and RMR system in place, from 1426 to 2625 m with KCl Glydril water-based mud, and from 2625 m to TD with RheGuard oil-based mud. The well was initially planned to be vertically drilled, but due to presence of corrals the location was moved approximately 80 m westwards.

Top of intra-Lange (informally Breiflabb Member) sandstones was penetrated at 3912 m (3879 m TVD MSL) and was water bearing without evidence of a hydrocarbon-water contact. Further Intra-Lange Formation (informally Smørflyndre Member) came in at 3952 m (3919 m TVD MSL) and has indications of hydrocarbon presence based on log interpretation without clear hydrocarbon-water contact. The Garn Formation was penetrated at 4141 (4107 m TVD MSL) m and can be separated into three lithostratigraphic intervals. The uppermost sandstone is a good reservoir. The bioturbated silt rich sandstone sequence below this is cemented and therefore of poor reservoir quality. An older sandstone of good reservoir quality is present at the base. The reservoir is saturated with gas-condensate at initial reservoir conditions with a gas-down-to contact at 4207.6 m (4174.4 m TVD MSL). The Ile Formation was penetrated at 4209 m (4175.9 m TVD MSL) and consists of several water bearing sandstone layers of good porosity and flow capacity. Three cores were cut, all in Garn Form
