Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
The 7318/12-2 is the replacement well for the 7318/12-1 Bone' well, which was abandoned due to unacceptable inclination in the top hole. The well is located in the Bjørnøya Basin of the Barents Sea. The primary objective was to test the 'Bone prospect in the Jurassic Realgrunnen Subgroup. Secondary objectives were the Triassic Fruholmen and Snadd Formations, depending on a success in the primary objective.
Operations and results
Wildcat well 7318/12-2 was spudded with the semi-submersible installation Scarabeo 8 on 13 January 2017 and drilled to TD at 3535 m in the Early Jurassic Nordmela Formation. No significant problem was encountered in the operations. By far the largest contribution to NPT was waiting on weather (63.7% of NPT). The well was drilled with seawater and hi-vis bentonite pills down to 833 m, and with EMS 4600 oil-based mud from 833 m to TD.
The Stø Formation, of the Realgrunnen Subgroup, was penetrated at a depth of 3417 m, and was found to be a very tight sandstone, with very low porosity and permeability. It was dry. There were no oil shows above the OBM in the well and the only significant formation gas in the well was a 63.2% gas peak at 2674 m, believed to be related to a fault. Based on this result the well was not extended to test the secondary Triassic targets.

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.
