1 FIAL WELL REPORT 34/ 5 S Licence no: PL93 Well: O 34/5 S of Sampling The modular dynamic tester was run to sample HC in the Tarbert Fm. 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 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.
