  • Well bore casing cutting tool having an improved blade structure and pad type stabilizers
    Patent number: 10344548
    Abstract: A downhole cutting tool for cutting sections or “windows” in tubular strings in wellbores has rotating cutters and a lower stabilizer section, both actuated by a fluid operated mechanism. The stabilizer section keeps the downhole cutting tool centralized in the tubular string. The cutters may have a robust profile and structure which enhances the window cutting function and permits passage of an operating rod to operate the stabilizer section.
    Type: Grant

  • Production tubing hydraulic release mechanism and method of use
    Patent number: 7748465
    Abstract: A release mechanism for removing a subsurface safety control valve from a production string in a well bore is mounted below the safety valve in operational engagement with the safety valve and the production string. The release mechanism has a two-part construction, with the upper part being normally locked to the lower part and released from the lower part when changing of the safety valve is required.
