Rotary Steerable System In Directional Wells
Rotary Steerable System RSS represents an evolutionary step forward in directional drilling technology, overcoming the drawbacks of steerable motors and conventional rotary BHA types. In steerable motors, to initiate a change in the wellbore trajectory, halt the rotation in such a position that the bend in the motor points toward the new trajectory. This mode, known as the sliding mode, typically creates higher frictional forces on the drill string.
