Use of Mechanical Specific Energy Calculation in Real-Time to Better Detect Vibrations and Bit Wear While Drilling

Mechanical Specific Energy (MSE) is a well-known concept to quantify the cutting efficiency of rock. Its utilization has significantly increased with electronic drilling recorders, especially in unconventional wells, to optimize the drilling process and reduce costs. A typical use is to compare the MSE to rock strength to see whether the right amount of energy is utilized at the bit and not wasted or dispersed...
