EARTH-BORING TOOL MONITORING SYSTEM FOR SHOWING RELIABILITY OF AN EARTH-BORING TOOL AND RELATED METHODS

摘要

An earth-boring tool monitoring system may generate a contour plot representing reliabilities of an earth-boring tool within a range of operating loads, the contour plot showing a range of reliabilities of the earth-boring tool from 100 percent reliable to 0 percent reliable and may overlay a plurality of markers over the contour plot, each marker representing an instance in time and representing operating loads of the earth-boring tool at that instance in time. Furthermore, the earth-boring tool monitoring system shifts the contour plot based on a cumulative amount of damage experienced by the earth-boring tool.
