What are the four major systems used on all rotary drilling rigs?
The four major systems used on all rotary drilling rigs are the power system, hoisting system, rotary system, and circulating system. Each system plays a distinct role in drilling operations by supplying the necessary energy, generating rotary motion, supporting the drill string, and transmitting drilling fluid for cooling and cuttings removal. Together, they enable efficient drilling operations, protect the drill bit, and maintain well control across different geological formations.
