Case 1 Logs showing the beginning of an oil kick.- Case 2 Detection of a water kick after swabbing at a pipe connection.- Case 3 Using the chromatograph to detect abnormal pressures in undercompacted series.- Case 4 Using calcimeters.- Case 5 Entry into a gas reservoir and kick control while tripping.- Case 6 Using resistivity measurements for the detection of salt beds.- Case 7 Circulating out a gas kick.- Case 8 Gas kick resulting in formation fracturation after closing the BOP.- Case 9 Water flowing well.- Case 10 Using temperature measurements and ‘d’ exponent calculations for the detection of undercompacted shales.- Case 11 Drilling through an evaporitic series.- Case 12 Drilling through a shaly sand series with interbedded salt layers becoming massive salt.- Case 13 Diamond-Bit turbodrilling through an evaporitic series.- Case 14 Drilling through a sandstone series with salt-cemented sand layers.
