Abstract: Tools and method for automatically controlling torque when making-up and/or breaking-down threaded connections between downhole assets such as drill pipe, drill collars, and BHA components. An iron roughneck may be controlled by, for instance, automatically monitoring and adjusting the fluid pressure of cylinders that ultimately provide the torque to the downhole assets. The torque may further be automatically controlled by automatically identifying the downhole assets and selecting a corresponding torque profile or target torque. Clamping force may also be controlled, and is optionally proportional to the target torque.

Abstract: A percussion drilling assembly includes a housing and a drill bit within a lower end of the housing. At least one of a piston or an anvil is within the housing above the drill bit. The drilling assembly also includes at least one sensor in at least one of the housing, the piston, or the anvil. A method of drilling includes drilling a formation with a percussion drilling assembly, the percussion drilling assembly having at least one sensor located in a component thereof. The at least one sensor may measure at least one property of the percussion drilling assembly while drilling. The measurements taken by the at least one sensor may be analyzed and a new percussion drilling assembly designed based on the analysis.
