What is a mud motor in directional drilling?

A mud motor is a drilling component that is used in directional drilling and vertical drilling, and is also often referred to as a downole motor, steerable motor, bent motor assembly, directional motor, and drilling motor. It consists of a power section, transmission, and lower end, usually directly behind the drill bit in the drilling string. The mud motor generates torque using pressurized fluid and utilizes this energy to penetrate the rock with the drill bit. ProDirectional is a leader in highly engineered mud motor technology.
