  • Tool deployment and cleanout system
    Patent number: 11608717
    Abstract: A variety of systems and methods are disclosed for cleaning a wellbore ahead of a well tool. The well tool is deployed on a tubular conveyance to a depth into a well. An interior surface of the well is wiped ahead of the well tool to dislodge debris from the interior surface of the well as the tubular conveyance advances downhole. The debris is filtered ahead of the well tool as the tubular conveyance advances downhole to keep the filtered debris away from the well tool. The well tool may then be used to perform a tool function when the tubular conveyance has reached the depth, without being affected by the filtered debris.
    Type: Grant
