Mud Motor Rotors connect directly to the drill bit in directional drilling for oil and gas discovery deep below the earth’s surface. The power section is a “positive displacement mud motor” combined with directional technology to steer the drill motor using tilting joints and sophisticated, telemetric, sensors. The motor converts the drilling fluid’s hydraulic energy into mechanical energy in the form of torque and rotational speed. This conversion is accomplished through the use of a spiral rotor that fits into a stator of similar shape, to form a tight seal. These systems are now capable of drilling within ±0.15° over depths to 18,000 ft. The rotors within the mud motors are called power section rotors, which are typically 5, 7 or 9 lobed with smooth spiral profiles in lengths as long as 8m with long leads of up to 40”. Fit snugly into an elastomer stator having one additional lobe contour with the same lead creates a moineau style progressive cavity positive displacement rotary drive unit. When the water based drilling fluid or “mud” is pressurized at the surface and pumped down the hole to the power section an extremely high torque low rpm drive is created to rotate the rock crushing drill bits.
