It proved difficult to establish seal and to achieve required mobility for sampling. Finally, the sampling was utilized at 70.5 m MD RKB / 496 m MSL (corrected for stretch in drill pipe) in the lower part of the Tarbert Fm after cleaning up for 6 hrs. Formation pressure was 790.7 bar, formation temperature was 56.8 C and the mobility was 4.6 md/cp. Three samples chambers were filled after pumping 2, 0 and 20 liters. o obvious cleanup could be detected by the downhole fluidanalyzers.
