Vibration Error Correction for the FOGs-Based Measurement in a Drilling System Using an Extended Kalman Filter

Vibration Error Correction for the FOGs-Based Measurement in a Drilling System Using an Extended Kalman Filter

Fiber-optic gyroscopes (FOGs)-based Measurement While Drilling system (MWD) is a newly developed instrument to survey the borehole trajectory continuously and in real time. However, because of the strong vibration while drilling, the measurement accuracy of FOG-based MWD deteriorates. It is urgent t...
