An is an automated control system used on drilling rigs (both for oil and gas exploration and scientific drilling). Its primary function is to control the weight applied to the drill bit automatically, rather than relying solely on manual manipulation by the driller.
An autodriller is an electronic control system that automatically manages the and rate of penetration (ROP) during drilling. It replaces manual air/hydraulic drilling controls, using setpoints and real-time sensor feedback (hookload, block position, mud pressure) to maintain consistent drilling parameters. autodriller
The rotational force required to turn the drill string.

– A mature, proven technology that improves ROP and reduces downhole dysfunction, but requires correct tuning, quality sensors, and a crew that understands its limitations. When used properly, it pays for itself through faster drilling and fewer stuck pipe incidents.
