Abstract

A method for determining gravity toolface azimuth that can include rotating a logging tool about a center axis; positioning an accelerometer sensor within the logging tool at a first radial distance from the center axis; positioning an angular gyroscope sensor within the logging tool at a second radial distance from the center axis; receiving, at a controller, accelerometer sensor data from the accelerometer sensor and angular gyroscope sensor data from the angular gyroscope sensor as the logging tool rotates; determining, via the controller, a radial acceleration component of the accelerometer sensor from the accelerometer sensor data; determining, via the controller, a gain and an offset of the angular gyroscope sensor based on the radial acceleration component; and determining, via the controller, the gravity toolface azimuth of the logging tool as a function of time based on the gain, the offset, and the angular gyroscope sensor data.
