NON-MAGNETIC DRILL COLLAR

TECHNICAL SUMMARY

Non-Magnetic Drill Collar (NMDC) is specialized tools extensively employed in the oil and gas industry to facilitate efficient drilling operations while minimizing magnetic interference. Orchid Energy can provide slick/spiral/flex/pony types of non-magnetic drill collar.
Constructed from low or non-magnetic alloys, such as stainless steel or non-magnetic steel composites, NMDCs offer a crucial solution to eliminate magnetic fields’ disruptive effects during drilling activities.
