Multiple inlets allow drillers to easily alter drilling methodologies from exclusively air drilling to mix-ing in water and drilling foams. Due to the increase in well depths and the complexity of drilling operations, the control of drill string serviceability is becoming more and more significant. Although the drill string is often a source of problems such as washouts, twist-offs, and collapse failures, it is seldom designed to prevent these problems from occurring.
