Abstract
A method for aligning a pump with a wellhead begins with the steps of attaching a target assembly to the pump and attaching an emitter assembly to the wellhead. The method continues with the step of emitting a beam of light from the emitter assembly to the target assembly. The method concludes with the step of determining the position of the pump with respect to the wellhead by evaluating the projection of the light beam on the target assembly. Based on this determination, the pump can be accurately aligned with the wellhead.
