General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but

Increasing the rotational speed, measured as revolution per minute (RPM), will also remove more rock per minute and will therefore improve the ROP. Drilling mud, flowing through the bit nozzles, re-moves the loose rock chips away from the bit face. Mud and flow related drilling properties like; mud-density, flow rate, and viscosity will ...
