Gyrocompass ER-Gyro-19

ER-Gyro-19 MEMS Gyroscopic Directional Module for Gyro Tools       
(Direct Replacement for Fluxgate Module)
 
Introduction
The ER-Gyro-19 is a revolutionary MEMS-based gyro directional module designed for direct, drop-in replacement of standard fluxgate modules. With fully compatible electrical interfaces and mechanical dimensions, it integrates seamlessly into existing probe and logging tool architectures—eliminating hardware redesign costs.
 
Utilizing strapdown inertial measurement technology by 3-axis navigation-grade MEMS gyro and 3-axis MEMS accelerometer, it delivers reliable azimuth, inclination, and tool face data. This module is unaffected by magnetic interference—ensuring accuracy where traditional magnetic tools fail.
 
Core Advantages
Pioneering High Accuracy in Small Inclination: Delivers effective azimuth and tool face precision even at small well inclinations, maintaining accuracy within 3.




Designed for Harsh Conditions: Features the most advanced MEMS technology and an all-solid-state design with superior shock and vibration resistance, performing reliably under intense random vibrations.




Rapid & Precise Alignment: Achieves 1 azimuth accuracy in just 30 seconds, and 0.5 accuracy within 90 seconds, maximizing operational efficiency.




Extreme Environmental Suitability: Fully calibrated and compensated across a wide temperature range of 5C to 125C.




Ultra-Compact Form Factor: Dimension 136.8mm x 20.3mm x 19mm. Replaces fluxgate sensors in situ with no system modifications, offering an immediate and cost-effective path to non-magnetic measurement capability.
 
Applications
Oil & Gas Drilling & Logging: for Measurement-While-Drilling (MWD)/Logging-While-Drilling (LWD) in cased holes, side-tracks, and wells with significant magnetic interference from drill strings, casings, or geological formations.




Cased-Hole Logging & Well Intervention: for gyroscopic surveys in production wells and for providing precise directional data for well abandonment, sidetracking, and re-entry operations where magnetic tools are unusable.




Pipeline & Utility Installation (HDD): for the accurate mapping of pipeline routes, especially in congested urban areas with existing underground utilities that create magnetic noise.
