Abstract:
1. A method of determining a speed of insertion or removal of piping from a well bore by evaluating a display of load data comprising the steps of: receiving from a transducer load data comprising a plurality of load data points; transmitting the plurality of load data to a monitor comprising a display; receiving at the monitor the plurality of load data points comprising a load data curve on the display, the load data curve comprising a plurality of data peaks; selecting at the monitor a time period on the display, the time period comprising at least one of the plurality of data peaks; determining with a computer communicably coupled to the monitor the total number of data peaks received on the display during the time period; calculating with the computer the speed of insertion or removal of the piping from the well bore by dividing the total number of data peaks by the amount of time in the time period; and generating as an output on the monitor the speed of insertion or removal of the piping from the well bore.
