Method and system for evaluating weight data from a service rig

Abstract From the Canadian patent

The present invention is directed to methods for an off-site supervisor or well owner to evaluate the rig load data provided by a well service rig at a well site by evaluating charts of sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and activities completed by the rig identified based on the data curves on the rig load data chart. In addition the hook load carried by the service rig can be determined by evaluating the rig load data charts of sensor data. Furthermore well bore and tubing conditions in the well can be analyzed based on the rig load data in the rig load data charts while tubing and rods are being pulled from …
