Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6407/1-9 was drilled to test the Egyptian Vulture prospect in the Grinda Graben in the Norwegian Sea. The primary objective was to confirm hydrocarbons in the Early Turonian Intra Lange Formation sandstones.
Operations and results
An 8 1/2 pilot hole NO 6407/1-U-1 was drilled off location to check for shallow gas down to section depth for 26 section. The well was drilled down to 912 m where a flow check confirmed gas bobbles with ROV. The U-1 pilot hole was cemented back, and it was decided to drill another pilot hole.
The second pilot hole, NO 6407/1-U-2, was drilled to 1445 m, flow checked several intervals and only minor gas bubbles was observed at seabed with ROV. The pilot hole was cemented back, and the planned main well location was moved to second pilot hole location.
Wildcat well 6407/1-9 was spudded with the semi-submersible installation West Hercules on 24 September 2021 and drilled to TD at 3914 m in the Early Cretaceous Lange Formation. Drilling to TD proceeded without significant problems, but hole stability issues created problems during logging. The well was drilled with seawater and hi-vis pills down to 1445 m, with Versatec oil-based mud from 1445 m to 3095 m, and with Exploradril oil-based mud from 3095 m to TD.
Numerous Intra-Lange Formation sandstones were penetrated in the interval 3618 m to 3651 m. Light oil was proven in sands in the interval 3715 to 3740 m. Pore pressures between 549 to 549.5 bar was recorded in the upper part of the oil-bearing sands. The only oil shows reported from the well were in these sands.
One core was cut from 3727 m t

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.
