Abstract
A drilling assembly for drilling deviated wellbores includes a drill bit and a drilling motor that provides rotary power to the drill bit. A steering device integrated into drilling motor assembly contains a plurality of force application members. In one embodiment, each force application member is adapted to exert an adjustable amount of force on the wellbore interior. A separate or common power unit at or uphole of the drilling motor provides power to the force application members. A control device and control circuit can cooperate to independently operate each of the force application members. An inductive transmission device can be used to transmit electrical signals and/or power between rotating and non-rotating section of the drilling motor. During drilling of a wellbore, the force application members are operated to adjust the force on the wellbore to drill the wellbore in the desired direction.
