Appraisal well targeting Middle Tarbert sandstones on down-thrown fault block west of Oseberg Delta S2 Field; Parkes prospect. Well sidetracked from gas injector 30/9-O-2 H and deviated SW. Possible oil pay at top Upper Tarbert at 3,656 m (3,162 m TVDSS), with main pay in Middle Tarbert from 3,745 m (3,213 m TVDSS) to oil-water contact at 3,796 m (3,242 m TVDSS); 34 m oil column reported in moderate to good quality reservoir. Pressure data and common oil-water contact indicate communication with Delta S2 and non-sealing fault. No cores/fluid samples. Well plugged back and gas injector drilled ahead and completed.
