How many degrees is the orientation accuracy always off? ER-Gyro-15 can help you get it right in one step

Do you often need to find the north and calibrate? Can't enter a small borehole? Especially, the correction is time-consuming and expensive. I believe these problems have troubled you for a long time, just because you didn't choose ER-Gyro-15.

[ER-Gyro-15]-Your ultra-precision orientation expert

The most advanced MEMS strapdown inertial navigation technology, more stable and reliable
MEMS strapdown inertial navigation technology removes the complex platform mechanical system, reduces costs, improves reliability and stability; at the same time, it shortens the startup time, and the warm-up time only takes a few seconds, which is more time-saving than traditional gyro orientation tools; 5-125℃ full temperature calibration compensation, adapting to various extreme environments.

The latest three-axis MEMS gyro technology subverts the size of traditional gyro tools and is extremely small.
The latest three-axis MEMS gyro technology is used. The diameter is only 30mm, the length is only 120mm, and the weight is ≤150g. It can be easily embedded in the narrow front-end space such as the probe tube, and is no longer limited by the working environment. It is the first choice for oil drilling. Thanks to its miniaturized design, ER-Gyro-15 not only supports point measurement and continuous measurement, but also can measure while drilling, which can quickly collect drilling data, control drilling trajectory, greatly shorten measurement time, and significantly improve operating efficiency. The all-solid-state design has excellent impact and vibration resistance. By integrating the real-time data of the three-axis MEMS gyroscope and the three-axis accelerometer, dynamic continuous tracking measurement of well inclination, tool face angle and azimuth can be achieved.
Equipped with high-precision MEMS gyro with self-seeking function, it is not affected by magnetic field and has ultra-high precision.

The gyro orientation technology based on the earth's rotation angular velocity sensing is adopted, which does not rely on magnetic field orientation and can independently determine the true north direction; 30s fast alignment, azimuth accuracy of 1.5°, 90s precise alignment, azimuth accuracy of 0.5°, reducing manual intervention, adapting to complex downhole environments, and truly achieving "fast and accurate, one-step"; the north-seeking accuracy can reach 0.25°secψ (1σ), the gyro tool face angle accuracy is 1°secL (L is latitude), and the well inclination angle alignment accuracy is 0.1° (1σ), with ultra-high precision pointing.

Actual application scenarios

Accurate orientation of casing window side drilling
In casing window side drilling operations, traditional magnetic inclinometers are easily disturbed by the magnetic interference of casing, resulting in azimuth measurement errors.
ER-Gyro-15 adopts MEMS gyro technology, which is not affected by magnetic fields and can provide high-precision azimuth data to ensure that the position and direction of the window point are accurate and correct.

Well logging in strong magnetic interference environment
Traditional magnetic inclinometers fail in cased wells, densely populated areas of adjacent wells, or near magnetic mineral layers.
The non-magnetic characteristics of the ER-Gyro-15 make it an ideal choice for such environments, ensuring reliable measurement data.

Re-entry and wellbore repair monitoring
In wellbore repair or re-fracturing operations, it is necessary to accurately measure the existing wellbore trajectory.
The ER-Gyro-15 can provide high-precision well deviation data to assist operations such as expansion tube wellbore reconstruction.
