The PDP is used to rotate the bit independently of the drill string. Mud motors used in directional drilling are fabricated with a slight bend that can range up to about 4 degrees. The vertical portion of the well is drilled normally with the entire drill string rotating. When the operator decides theyâre ready to go directional, drilling stops and the directional driller orients the drill string so that the bend in the mud motor points in the direction that everyone thinks the well should go. At that point, the PDP is engaged and only the bit rotates.
