摘要：
A control system for moving a bottom hole assembly at an end of a coiled tubing string in a wellbore includes a controller configured to move the bottom hole assembly at an initial rate, unless the controller determines that moving the bottom hole assembly at the initial rate causes a predetermined threshold parameter to be reached, whereupon the controller is configured to default to moving the bottom hole assembly at a safe rate.
