Abstract
A directional drilling device for drilling a wellbore having a wall, the device including an outer housing, a driveshaft located at least partially within and selectively rotatable with respect to the outer housing. The device also includes extendable members moveable to extend radially outwardly from the outer housing and so as to apply a force onto the wellbore wall and move the device off-center in the wellbore in a direction. The device further includes a hydraulic actuation system operable to control hydraulic fluid to extend and retract of the extendable members. The rotational orientation of the extendable members is controllable by rotation of the outer housing by the driveshaft and the rotational orientation of the extendable members and the outer housing and thus the direction may be maintained by extension of the extendable members into contact with the borehole to restrain the outer housing from rotating.
