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.

Description

STATEMENT OF RELATED PATENT APPLICATION [0001] This non-provisional patent application claims priority under 35 U.S.C. § 119 to U.S. Provisional Patent Application No. 60 / 716,612, titled Interpretive Techniques Using Sensor Data, filed Sep. 13, 2005. This provisional application is hereby fully incorporated herein by reference.FIELD OF THE INVENTION [0002] The technical field of the present invention relates generally to evaluation of data concerning servicing hydrocarbon wells and more specifically to an evaluation of data obtained from a computerized work over rig adapted to record and transmit data concerning well servicing activities and conditions at a well site. BACKGROUND OF THE INVENTION [0003] After a well has been drilled, it must be completed before it can produce gas or oil. Once completed, a variety of events may occur to the formation, the well and its equipment that requires a “work-over.” For purposes of this application, “work-over” and “service” operations are used...

Benefits of technology

[0008] For one aspect of the present invention, a method of determining the accuracy of an activity listing for activities completed by a well service rig at a well site can include determining a first activity from an activity listing, such as a Gantt chart. Charts of sensor data can be evaluated. The charts can be of sensor data obtained from sensors on the well service rig and the data can be associated with work completed at the well site by the service rig, other service vehicles or by third party operators. An evaluation of the charts of sensor data can be conducted to determine if the activity listed in the Gantt chart corresponds with the data that is being received from the sensors and displayed on the data charts.

[0009] For another aspect of the present invention, a method of determining the completion times for an activity completed by a well service rig at a well site can be determined by evaluating one or more

Problems solved by technology

Further, most well owners own more than one well in a given field and the invoices from the various companies may confuse the well name with the services rendered.

Also, if an accident or some other notable incident occurs at the well site during a service operation, it may be difficult to determine the root cause or who was involved because there is rarely any documentation of what actually went on at the well site.

Of course, a well owner can have one of his agents at the well site to monitor the work-over operations and report back to the owner, but such “hands-on” reporting is often times prohibitively expensive.
