Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6507/8-10 S was drilled to test the Grind prospect east of the Heidrun Field in the Grinda Graben in the Norwegian Sea. The primary objective was to prove presence and commercial volumes of movable hydrocarbons in the Early Jurassic sandstones of the Tilje and Åre formations.
Operations and results
A 9-7/8" pilot hole 6507/8-U-3 was drilled to 1150 m in parallel to drilling 6507/8-10 S 36" x 42"-hole, 12 m north-west of the main bore location. Dual drilling was a first for the West Phoenix. No shallow gas or shallow water flows were observed during drilling.
Wildcat well 6507/8-10 S was spudded with the semi-submersible installation West Phoenix on 21 March 2020 and drilled to TD at 2399 m (2350 m TVD) in the Early Jurassic Åre Formation. Due to adverse weather nine days were spent as WOW, otherwise operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 1150 m and with Versatec oil-based mud from 1150 m to TD.
The Tilje Formation was encountered at 2053.0 m and comprised 150 m sandstone with minor siltstones and claystones. The Åre Formation consisted of 197m sandstone with minor siltstones and coal and was encountered at 2203.0 m. Petrophysical analysis indicated good reservoir properties (24-25% porosity) in both formations with 98 m net reservoir sand in Tilje and 98 m net reservoir sand in Åre. Both formations were dry. “Dead oil” was observed in a very few cutting samples, but it has been interpreted to be associated with coal layers in the Åre Formation.
No cores were cut. No logs were run on wire line and no fluid sample was taken.

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
