North Seeking Gyro is designed to seek north automatically. It is free from magnetic interfere and there is no need to calibrate on ground. The system adopts high precision dynamically tuned gyro sensor to measure the inclination, azimuth and tool face, etc. It is widely used in multi-branch wells, casing and open well and orientation survey in the oil and gas field.

North Seeking Fiber Optic Gyro

---

The fiber optic gyro adopts high precision gyro sensor, which enhances the survey accuracy and range.  Meanwhile, as there are no moving parts, the anti-vibration is solved effectively. And it can be used for the survey of the high inclination well.

Gyro-While-Drilling                     

 On the basis of the traditional gyro survey tools, Z-axis is added on LHE5201 
Steering gyroscope. It works in the wireline steering mode, and monitor the gyro 
high-side in real-time.  The directional drilling efficiency is greatly improved.
