ABSTRACT:
A method and apparatus operable on a wireline logging cable for sampling and testing bore hole fluids, transmitting the results obtained from such testing to the surface for determination whether or not the particular sample undergoing testing should be collected and brought to the surface. The apparatus comprises a downhole tool having an inflatable double packer for isolating an interval of the bore hole coupled with a hydraulic pump, the pump being utilized sequentially to inflate the double packer and isolate an interval of the bore hole and to remove fluids from the isolated interval to test chamber means where resistivity, redox potential (Eh) and acidity (pH) are determined, and finally to dispose of selected samples to one or more sample container chambers within said tool or to reject them into the bore hole if not selected.
