General
Exploration well 6407/12-1 is located on the western edge of the Trøndelag Platform in PL176, some 13 km South of the Draugen platform. It was drilled to test the hydrocarbon potential of the Upper Jurassic sands of the Rogn Formation, which is the main reservoir unit in the Draugen Field. The second objective was to log and sample the upper 20 m of the Middle Jurassic Garn Formation.
Operations and results
The well was spudded on 7 July 1999 with the semi-submersible installation "Mærsk Jutlander" and drilled to a total depth of 1805 m in sandstone of the Garn Formation. It was drilled with sea water and Hi-vis bentonite pills to 714 m and with BARASILC silicate mud from 714 m to TD. The well found 2.3 m of oil-bearing sands in good quality reservoirs of the Rogn Formation. The Rogn Formation in the well is in pressure communication with the Rogn Formation reservoir of the Draugen Field. An oil MDT sample was acquired from 1660.7 m in the Rogn Formation. Sampling occurred extremely slowly despite a recorded mobility of 249 md/cp and a high porosity indicated from the density log. This suggests potential plugging of the probe due to the unconsolidated nature of the Rogn sandstone. The Garn Formation came in at 1763 m. No conventional core was cut in the well. The well was plugged and abandoned on 15 July 1999.
