  • METHOD AND SYSTEM FOR REDUCING FRICTION IN RADIAL DRILLING AND JET DRILLING OPERATIONS
    Publication number: 20240093623
    Abstract: Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with a lubricant. Lubrication of the deflector show can be accomplished by applying a wet lubricant to the interior of the deflector shoe or spraying a dry lubricant on the interior of the deflector shoe. The method can further include coating a hose and/or a jet nozzle, passing the hose and/or jet nozzle through the coated interior of the deflector shoe. The method can further include coating components of a milling cutter, and passing the components of the milling cutter through the coated interior of the deflector shoe. An apparatus for reducing friction in a radial drilling application is also disclosed.
