Method and system for evaluating task completion times to data

Abstract

The present invention is directed to methods of evaluating the operations of 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. An activity listing or Gantt chart can be reviewed and each activity verified by viewing charts of sensor data obtained during that purported activity. In addition service rig downtimes can be determined and evaluated through the evaluation of charts of sensor data. Furthermore, activities and completion times for each activity can be determined by evaluating charts of sensor data obtained from sensors on the service rig or at the well site to verify the operations of the service rig, to improve the efficiency of the operators by identifying long activities and providing additional instruction, and provide improved billing to customers by correcting activities and the time associated therewith.
