North Seeking Gyro

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.

Technical parameters


Parameters Range Accuracy Note
Inclination 0～60° ±0.2°
Azimuth 0～360° ±2.0°
Gravity high side tool face 0～360° ±0.5°
Gyro high side tool face 0～360° ±0.5
Load resistance ≤ 200 Ω
 Wireline mode
Working temperature 0～75℃
0～200℃
 Normal temperature
with thermal shield , work for 4 hours continuously


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.

Technical parameters


Parameters Range Accuracy Note
Inclination 0～90° ±0.1°
Azimuth 0～360° ±2.0°
Gravity high side tool face 0～360° ±0.5°
North tool face 0～360° ±2.0°
Measuring time for each survey ≤ 68 s

Load resistance ≤ 200 Ω
 Wireline mode
Working temperature 0～70℃
0～200℃
 Normal temperature
with thermal shield , work for 4 hours continuously


North Seeking Continuous Gyro

North Seeking Continuous Gyro, consisting of reliable gyro sensor and accelerometer, is used in the continuous survey of the well trajectory by use of strapdown inertial navigation technology. Compared to point survey gyro, continuous gyro shortens the survey time, reduces the overall cost and construction risk greatly.
