  • Publication number: 20150060048
    Abstract: A wireline guide tool having a top section with an inner concave portion and a bottom section designed to attach to a stinger or on/off tool provides advantages for passing a wireline into the stinger. The stinger is attached to a packer within a casing of a well bore, without any tubing present. The inner concave portion of the top section of the wireline guide tool captures the wireline and funnels it into the stinger, effectively eliminating problems with achieving a proper alignment of the wireline for entry into the stinger.

  • Patent number: 4007790
    Abstract: A new and improved apparatus and method for lowering the apparatus downwardly in a drill string on a wireline to releasably engage a recess in a threaded joint or collar of the drill string to prevent further downward movement of the apparatus and to thereafter detonate an explosive by manipulating a wireline actuated jar with repeated downward blows for exerting a jarring force to the joint as a result of the explosion to release the threads at the joint upon simultaneous application of a back-off torque to the drill string. The apparatus can be released and removed from the well without breaking or damaging the collar locating and supporting portion of the apparatus.
