Detailed Description

Non-magnetic drill collar 

Non-magnetic drill collar is made from low carbon high-chromium manganese alloy steel, it is refined with strict chemical
composition control, specially forged to achieve high strength mechanical properties and low magnetic permeability, excellent inter-granular corrosion cracking resistance, and wear resistance.
Non-magnetic drill collar used with MWD (Measurement While Drilling) and LWD (Logging While Drilling) for Directional Drilling applications, to allow magnetic surveying of the well trajectory using instruments inside the drill string.
Magnetic survey instruments (MWD) run in the hole located in the non-magnetic drill collar to allow the measurement of the earth’s magnetic field without magnetic interference. Survey instruments are isolated from magnetic disturbance caused by steel components in the BHA (Bottom Hole Assembly) and drill pipe.
