Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 7325/4-1 was drilled to test the Gemini prospect in the Hoop Fault Complex in the Barents Sea. The primary objective was to prove oil in the Realgrunnen Subgroup. Secondary objective was to test the Late Triassic Snadd Formation.
Operations and results
A 9 7/8" pilot well (7325/4-U-1) was spudded on 18 July 2017. It was drilled approximately 40 m south-east of the main well location. TD was set at 725 m in Hekkingen Formation, equivalent to the planned setting depth of the 13 3/8" surface casing shoe in the main well. No shallow reservoir was detected.
Wildcat well 7325/4-1 was spudded with the semi-submersible installation Songa Enabler on 19 July 2017 and drilled to TD at 1210 m in the Late Triassic Snadd Formation. Operations proceeded without significant problems, but the sidewall cores from the well were contaminated by a leak of hydraulic oil from the XL-Rock tool. The well was drilled with Seawater and hi-vis sweeps down to 731 m and with KCl/Pol/GEM water-based mud from 731 m to TD.
The top of the reservoir in the Stø Formation, Realgrunnen Subgroup, was encountered at 772 m. The reservoir was seen to be hydrocarbon-bearing, with an approximately 18.5 m gas column. Drop in resistivity and increase in oil shows indicate a gas-water contact at 790.5 m, but this is not conclusive. In the Snadd Formation, a 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.
