Abstract

Systems and methods are presented for drilling a wellbore with a portion having a short radius of curvature. The systems include a drill assembly having a motor and a tubular housing. An actuator is at least partially disposed within the tubular housing and couples the motor to the tubular housing. The actuator is configured to selectively articulate the drill assembly between a straight configuration and a bent configuration. At least one torque anchor is fluidly-coupled to a trailing end of the drill assembly. Methods are presented for selectively articulating the drill assembly to form the wellbore, including the portion having short radius of curvature. Other systems and methods are presented.
