Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Friction between components moving through deflector shoes in radial and jet drilling operations leads to reduced component life, increased power requirements, and higher operational costs and time.
Innovation Solution
Coating the interior of deflector shoes with lubricants, such as tire shine, fluoropolymer coatings, tungsten disulfide, or Never Seez® anti-seize compound, and roughening the surface to reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If components are moved through deflector shoes in radial and jet drilling operations, then drilling operations can be performed, but friction increases leading to reduced component life, increased power requirements, and higher operational costs
Solution Approach 1:
The patent introduces a lubricant as an intermediary substance between the deflector shoe interior surface and the components passing through it. The lubricant reduces direct contact and friction between these surfaces, thereby reducing power requirements and energy loss during drilling operations while maintaining operational efficiency
2Productivity
If components are moved through deflector shoes in radial and jet drilling operations, then drilling operations can be performed, but friction increases leading to reduced component life
Solution Approach 1:
The lubricant acts as a protective intermediary layer that reduces wear and friction between the deflector shoe interior surface and components. This extends component life and improves reliability while maintaining drilling operation efficiency
3Productivity
If components are moved through deflector shoes in radial and jet drilling operations, then drilling operations can be performed, but friction increases leading to higher operational costs
Solution Approach 1:
The lubricant reduces friction and energy loss during component movement through the deflector shoe, thereby reducing operational costs while maintaining drilling operation efficiency

AI summary
Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with at least one lubricant. Lubrication of the deflector shoe can be accomplished by applying a dry lubricant to the interior of the deflector shoe, allowing the dry lubricant to harden, and applying a wet lubricant over the hardened dry lubricant. The interior surface of the deflector shoe may be roughened prior to application of the lubricant. The method can further include coating a hose and/or a jet nozzle, and 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.
