Title
(EN) Steering head with integrated drilling dynamics control
Abstract
(EN) A method, apparatus and computer-readable medium for reducing a vibration of a drill string in a borehole. A sensor of the drill string obtains one or more measurements of a parameter of the vibration. A processor determines at least one force for controlling the measured vibration from the measured parameter. At least one actuator applies the determined at least one force against the borehole wall to control the vibration of the drill string.
