Abstract

An embodiment of a method of predicting drilling assembly performance includes: acquiring measurements of electromagnetic (EM) radiation emitted due to destruction of formation materials by a drilling assembly during a drilling operation; selecting input parameters, the input parameters including drilling assembly parameters, operational parameters, and the measurements of the EM radiation; supplying the input parameters to a mathematical drillability model; and generating a rock drillability parameter using the drillability model and the input parameters, the rock drillability parameter providing an indication of drilling performance.
