Non-Magnetic Heavy Weight Drill Pipe: Precision Weighting with Survey-Grade Accuracy

Non-Magnetic Heavy Weight Drill Pipe: Precision Weighting with Survey-Grade Accuracy

The Magnetic Interference Challenge in Directional Drilling

Standard drill pipes create magnetic distortion that causes:

-Azimuth errors up to 3° in high-latitude wells

-Well collision risks from inaccurate trajectory data

-Costly correction runs requiring additional rig days
