A novel correlation identifying inefficient drilling conditions is presented using experimental and field data. Historically,
Mechanical Specific Energy (MSE) has been used to improve the drilling performance with mixed results. Drilling Specific
Energy (DSE) is the amount of energy required to destroy and remove underneath the bit a unit volume of rock. DSE
includes axial, torsional and hydraulic energy. DSE is different than MSE because it includes a hydraulic term. The initial
MSE correlation (Teale, 1964) has been modified to accommodate the new hydraulic term.
Experimental and field data presented on the paper show that DSE can be used to identify inefficient drilling conditions.
Experimental results illuminate the importance of including bit hydraulics into the specific energy analysis for drilling
optimization. Field results reveal specific patterns for inefficient drilling conditions such as; bit balling and friction limited
