CGRO Gyro is TOT’s latest designed and applied north-seeking Gyro with more convenience. No need to exchange the measurement mode, it can conduct the measurement in 70° inclination. North-seeking process could be carried out in slight inclination, also could use wellhead north-seeking in un-ceasing environment ( such as on the vibrating offshore platform) -------utilizing dynamic north-seeking to find a standard position for quick alignment.
