enough pressure differential around the tool in the tool borehole annulus 110 the lateral force can also be achieved with lateral orifices 40 placed in the hole gauge 10 next to the drill bit 50 itself where a smaller gap h between the tool 50 and the borehole 110 is easier to maintain during drilling the smaller the gap the bigger the hydraulic side force as the entire drilling bha is rotated during drilling including the lateral orifices one or more lateral orifices are open only when they are approximately opposite to the desired change in drilling direction while all other lateral orifices are closed until they get approximately opposite to the desired change in drilling direction as the entire bha rotates around its longitudinal axis the corresponding opening and closing of the lateral orifices or opening and closing of the drilling fluid paths to these orifices can be achieved and controlled by using existing methods for opening and closing fluid paths to the steering pads of a traditional bias or steering unit and controlling the process with a traditional control unit that performs necessary measurements and provides control and steering functions for example a counter rotating valve that rotates at the same rotational speed as the drilling bha but in the opposite direction can be used to open and close the drilling fluid path to the lateral orifices thus keeping the fluid.
