  • Method for synchronizing downhole tractor and winch deployment
    Patent number: 11454076
    Abstract: A method for synchronizing downhole tractor and surface winch deployment includes inserting into a wellbore a tool string connected to a wireline, where the tool string includes a variable speed tractor. The method also includes deploying the tractor, and deploying the wireline from a winch. The method further includes dynamically monitoring, by a device disposed downhole, a wireline tension as an indicator of synchronization of the tractor and winch.

  • Method for Synchronizing Downhole Tractor and Winch Deployment
    Publication number: 20210164309
    Abstract: A method and system for synchronizing downhole tractor and surface winch deployment includes inserting into a wellbore a tool string connected to a wireline, the tool string comprising a variable speed tractor, deploying the tractor, deploying the wireline from a winch; dynamically monitoring, by a device disposed downhole, a wireline tension as an indicator of synchronization of the tractor and winch, and adjusting, by the device, the tractor speed in response to a disparity in tension to match the winch speed.
