How Does Drilling Equipment Work?

Generally, a powerful motor either at the surface or downhole turns a string of pipe with a drill bit connected to the lower end. A drill bit, sometimes super-hardened by diamond chips in its composition, has jagged edges capable of crushing and chewing through rock. During the drilling operation, a fluid known as drilling mud circulates down through the piping, passes through holes and the drill bit and then travels up again through the wellbore to the surface, carrying with it bits of rocks known as “cuttings.” Drilling mud also keeps the wellbore filled with fluid to help equalize pressure and keep water from entering the wellbore.
