Abstract
A method of controlling rates of moving a coiled tubing string in a wellbore includes providing an injector head control system for moving a bottom hole assembly at an end of the coiled tubing string in the wellbore, that maintains operating settings of the injector head if the control system determines that the bottom hole assembly is moving in the wellbore within a range of rates, and varies operating settings of the injector head if the control system determines that the bottom hole assembly is moving in the wellbore outside the range of rates, to thereby revert to moving the bottom hole assembly in the wellbore within the range of rates. The control system determines whether the bottom hole assembly is moving within or outside the range of rates based on one or more sources of feedback from both the bottom hole assembly and the injector head.
