Abstract
A method for surveying a wellbore includes rotating a wellbore surveying tool in a wellbore. The wellbore surveying tool includes a plurality of magnetometers, a plurality of accelerometers, and, optionally, a plurality of temperature sensors. Sensor measurements are made while the survey tool rotates in the wellbore. A failed accelerometer or a failed temperature sensor is automatically detected from the accelerometer measurements or the temperature measurements. Corrected sensor measurements are computed for the failed sensor from selected ones of the magnetometer measurements, the accelerometer measurements, and the temperature measurements and used to further compute at least one of a wellbore inclination or a wellbore azimuth.
