Abstract
A rotary steerable system including a plurality of extendable pads deployed in a drill collar. Each of the pads is configured to extend radially outward from the drill collar and engage a wellbore wall and steer a direction of drilling. A plurality of digital valves is in fluid communication with corresponding ones of the plurality of extendable pads such that opening one of the plurality of digital valves provides high pressure drilling fluid to the corresponding pad thereby radially extending the pad. An electronic control unit deployed in a roll-isolated housing is configured to independently open and close each of the plurality of digital valves via a communications signal.
