Abstract
A method for motion compensation includes obtaining measurements related to heave at a surface of a rig, transmitting the measurements to a processor, and automatically transmitting a control signal from the processor to a motion compensation component in response to the measurements. The motion compensation component is a slip joint and is attached to a drill string located in the wellbore. The method may also include activating the motion compensation component to compensate for motion in response to the signal and preventing axial or rotational movement of a portion of the drill string below the motion compensation component.
