Abstract
A method of handling pipe segments during makeup and breakout of a drill string. The method uses a hydraulic circuit, which provides fluid to a motor or motors for translating a drill pipe segment. The drill pipe segment is supported by a carriage, which places the segment next to a drill string for addition thereto. Hydraulic pressure within the circuit is monitored to determine if a pressure fluctuation exists. If so, the translation speed is adjusted by modifying the hydraulic fluid flow to the motors. Sensors may be utilized to determine whether or not the system is in a 'transition zone' and therefore ready for pressure monitoring for makeup and breakout functions.
