Abstract
A rotary steerable system including a steering section and a control section. The control section includes a modular control system that is field detachable from a remainder of the control section. The modular control system includes one or more modules that are field detachable from the other modules and a remainder of the modular control system. Examples of the modules of the modular control system include a power module configured to generate electrical power or electromagnetic field rotation from hydraulic power, a control module configured to control actuation of one or more pistons in the steering section, and/or a flow control module configured to selectively allow fluid flow into one or more distribution channels leading to the one or more pistons of the steering unit.
