摘要：
Systems and methods for monitoring a position of a service tool in a wellbore are provided. The service tool can have a sensor assembly coupled thereto and be positioned within the wellbore. The service tool can be moved within the wellbore. The distance travelled by the service tool in the wellbore can be measured with the sensor assembly. The position of the service tool in the wellbore can be determined by comparing the distance travelled to a stationary reference point.
