Abstract

Active stabilization is provided. In one possible implementation a drilling tool associated with a drill bit includes one or more rotation alteration devices configured to alter a rotational radius of a drill string. The drilling tool also includes at least one active stabilizer rotatively attached to the drilling tool, as well as a variable brake configured to control a rotation of the at least one active stabilizer relative to the drilling tool. In another possible implementation, a drilling tool includes an active stabilizer rotatably coupled to the drilling tool, as well as an actuation system configured to control a torque placed on the active stabilizer through contact with a wall of a borehole.
