  • Method and apparatus for testing the integrity of the electrical insulation of a well logging sonde
    Patent number: 4291267
    Abstract: Apparatus for testing a logging sonde having a surface including elements which are electrically insulated the one from the other comprises an enclosure within which the sonde may be positioned. Conductive fluid under pressure is introduced into the enclosure so as to establish electrical conduction paths between different, spaced apart points on the surface of the sonde. Electrical communication between respective ones of the elements and the exterior of the enclosure is effected so that the sonde may be tested such as by deriving through operation of the sonde a measurement of the known resistivity of the enclosure wall.
