MUD MOTORS SELECTION

       The drilling mud motor uses different rotor and stator configurations to provide optimum performance for the desired drilling operation, typically increasing the number of lobes and length of power assembly for greater horsepower. In certain applications, compressed air, or other gas, can be used for mud motor input power. Normal rotation of the Drilling Bit  while using a mud motor can be from 60 rpm to over 100 rpm. So there are some factors affecting drilling mud motors selection.
