Directional drilling involves any attempt to intentionally divert the path of the wellbore and is almost always done to access otherwise difficult-to-reach deposits, such as under a lake or mountain. Using a PDC bit, the wellbore first goes straight down to a predefined depth. When the drill is pointed at the desired angle the force needed to progress through the rock formation comes from the rotation of the PDC bit and the Weight On Bit provided by the drill string. In addition to the special motorized tricone, directional drilling also requires special equipment to measure the progress while drilling.
