WirelineRun 1C

The primary objective of the MDT run was to obtain a fluid sampleFollowing the problems encountered with differential sticking in well 6407/9-9T2, whichpreceded this well, the MDT tool length was kept to a minimum. The pumpout module wasomitted and it was planned to clean-up the sample by dumping into a 6 gallon chamber. Thischamber, however, did not open due to an electronics failure. The first sample was taken at1660.4 m MDRKB (corrected for depth-shift error) into a 2.3/4 gallon chamber. Samplingoccurred extremely slowly, so after almost an hour it was aborted and an improvedpermeability interval sought. Fluid was sampled into a 1 gallon chamber at 1660.7 m MDRKB(corrected for depth-shift error). Once again, sampling occurred extremely slowly despite arecorded mobility of 249 md/cp and a high porosity indicated from the density log. Thissuggests potential plugging of the probe due to the unconsolidated nature of thesandstone. A gravel pack was not used for the probe due to its failure in well 6407/9-9T2, buta filter was used instead.

It appeared to be contaminated with mud filtrate and lowgravity solids.
