ABSTRACT:
An apparatus for drilling oil and gas wells includes an articulated drilling assembly having a bit which is powered by an air motor pressurized by air or gas delivered from the surface of the earth via a coiled tube. A torque arrestor is used to keep the drilling assembly from rotating with the bit. The apparatus is suitable for drilling horizontally within the earth as well as vertically.
