Magnetic Shielding During MWD Azimuth Measurements and Wellbore Positioning

Abstract

This observed time dependency of the magnetic shielding is so far unknown to the surveying industry. The effect, combined with analysis of directional data, can explain errors encountered in directional surveying. Recommendations for how to minimize such errors are presented.
