  • Wellbore history
    General
    Well 6707/10-1 was the first well drilled in PL218 and the first in the Vøring Basin deepwater area. The well targeted a tilted fault block on the Nyk High comprising Late Cretaceous sandstones with a pronounced flat spot. The main objectives of the well were to establish the presence, quality, and fluid content of the Campanian age Nise Formation. The underlying Santonian age Lysing Formation provided a secondary target.
    Operations and results
    Wildcat well 6707/10-1 was spudded with the semi-submersible installation "Ocean Alliance" on 19 April 1997 and drilled to TD at 5039 m in Late Cretaceous sediments of the Kvitnos Formation. The well was drilled water based with "BARASILC" silicate mud with KCl and GEM GP (glycols) from 2240 m to 2890 m and with KCl/NaCl/GEM GP/Polymer mud from 2890 m to TD. Top Nise Formation was penetrated at 2957 m, 1 m deeper than the revised depth prognosis based on an intermediate VSP run. The reservoir was recognized by an abrupt decrease in LWD gamma combined with increased gas levels and the appearance of sand in the cuttings. Wire line logging and sampling confirmed a gas column from 2957.5 to 3113.5 m. A total of nine cores were cut over the interval 2967 - 3145 m with a total recovery of 171 m (96 %). Poor shows were recorded in cores throughout this reservoir section, down to the base of core 9, where moderate shows were seen in the interval 3140 - 3145 mBRT. One 27 m core (core 10) was cut in the secondary target (4118 - 4145 mBRT). This core had fair shows at the top. No shows were seen in the drilled cuttings. Altogether 10 MDT fluid samples were taken in the Nise Formation. Seven of these were taken from 2964 to 3086 m RKB in the reservoir zone, two samples were from 3114.5 m just below the gas-water contact, and one from further down at 3195 m. The MDT samples were contaminated with mud, but PVT flash to stock tank conditions gave a consistent gas gravity of 0.59 relative to air and a GOR in excess of 117000 m3/m3. The well was plugged and abandoned as a gas discovery with oil shows.
