Overview
This document outlines the application of magnetic technologies in the oil and gas industry, focusing on the MagneGear™ RMG and LMG systems. These systems are designed to enhance drilling and safety operations through innovative magnetic gear solutions.

Specifications
The MagneGear™ RMG (Rotary Magnetic Gear) is designed for use with drilling motors such as turbodrills and positive displacement motors (PDMs). It features a totally sealless and non-contacting design, capable of force or speed multiplication/reduction with a wide range of ratios. The system is scalable to any size or torque requirement, with the output shaft capable of rotating in the same or opposite direction to the input shaft.

Procedures and Applications
The RMG is configured to isolate axial forces, preventing the transfer of high axial loads from the bit end to the PDM or turbodrill. High torque densities are achievable, with a torque density greater than 500 lb/ft per linear foot in a 9-5/8” diameter. For smaller diameters or higher gear reduction ratios, multiple stages can be utilized, achieving up to a 1200:1 reduction ratio in a 6-1/2” or smaller diameter.

Norms and Recommendations
The smallest practical diameter for downhole applications requiring moderate-to-high torque output is 3-1/2”, unless no mud flow is required through the RMG. Without flow requirements, the RMG can be applied in diameters of 2” or less.

MagneGear™ LMG
The LMG (Linear Magnetic Gear) is applied to tubing retrievable surface-controlled subsurface safety valves (SCSSVs). It provides force multiplication, allowing a 500-pound linear force to yield 3,000 pounds on the tubular valve actuator. This system can replace synchronous 1:1 ratio actuators, reducing the force required by the prime actuator by 80% or more.

Key Benefits
The MagneGear systems offer significant advantages in smart completions and microhole drilling, providing force multiplication and speed increase capabilities. These systems allow for lighter and smaller prime movers, enhancing efficiency and operational flexibility.
