Abstract

A system is provided including a coiled tubing injector including at least two gripper chains for gripping a coiled tubing and a gripper system for generating a gripper force applied to the at least two gripper chains by adjusting gripper pressure on at least one gripper cylinder. A gripper controller is configured to determine a minimum gripper pressure and a maximum gripper pressure for the gripper cylinders, based on a current set of parameters related to lowering the coiled tubing into a wellbore or pulling out the coiled tubing from the wellbore. The gripper controller selects a target gripper pressure between the minimum gripper pressure and the maximum gripper pressure based on a historical data model and sets the target gripper pressure for the at least one gripper cylinder.
