ENERGY EFFICIENT SYSTEM (MSE)

Definition: Energy required to destruct the rock (system efficiency)

CCS = Eb*MSE

MSE = (WoB/ ���)+(120*N*T/��*RoP)

Where: (At bit measurements - important)

CCS - Confined compressive rock strength

MSE - psi

WoB - lbs

r - hole radii (in)

N - rpm

T - torque (ft-lbs)

Eb - Efficiency at bit (%) (35% @ horizontal - 60% in vertical)

decreases further as the bit wears or gets damaged from vibration

The HI Tool™ improves Eb by increasing the

energy getting to the bit; reducing the system

energy loss from vibration.
