Positive-displacement motors (PDMs) are types of downhole drilling tools used in directional drilling operations. They are also known as positive-displacement mud motors. PDMs are powered by the flow of drilling mud or drilling fluid, which is pumped down through the drillstring and into the motor. As the mud flows through the motor, it drives a rotor, which turns a drill bit at the bottom of the hole.
PDMs have a number of advantages over other types of drilling motors. They are capable of generating high torque at low speeds, making them ideal for drilling through hard formations or for steering the drill bit in a specific direction. PDMs are also less prone to damage from shock and vibration than other types of motors, and they can operate at higher temperatures and pressures.
PDMs are commonly used in the oil and gas industry for drilling directional and horizontal wells, as well as in other applications where precise drilling control is needed. They are available in a variety of sizes and configurations to meet the needs of different drilling operations.
