PREDICTIVE LITHOLOGY AND FORMATION TYPE FOR DOWNHOLE DRILLING

摘要

A system includes a drill string having a drill bit to drill a target wellbore, a processor, and a machine-readable medium. The machine-readable medium having program code executable by the processor to cause the processor to determine a mechanical specific energy (MSE) response during drilling of the target wellbore and determine a property of a formation around the target wellbore based on the MSE response.
