  • Wire line well tool and method
    Patent number: 4033413
    Abstract: A new and improved wire line operated well tool apparatus and method utilizing a downhole transformer for sensing and testing conditions in a well, such as temperature, incline, and the like.
    Type: Grant
    Filed: December 4, 1975
    Date of Patent: July 5, 1977
    Assignee: W. R. Grace & Co.

  • Apparatus for sensing metal in wells
    Patent number: 4023092
    Abstract: A new and improved wire line operated well tool for sensing metal in wells and the like, wherein a pair of coils spaced along the tool axis are moved through the well and respond unequally to ferrous material in the well. The coils are activated on alternate cycles of AC energy supplied from the surface, and the AC responses are transmitted back to the surface to indicate the location of the ferrous material. Means are provided to block any DC pulses, as could be caused by galvanic action, from disrupting the meaningful data.
