Abstract

An apparatus for use in drilling a high angle or horizontal borehole has a body for coupling to a drill string and one or more traction members mounted for rotation on the body. The apparatus defines a first, passive, configuration and a second, active, configuration in which the traction member urges the apparatus along the inner wall of the borehole.
