Non-magnetic drill collars are specialized drill collars that are made from materials that are not magnetic, such as titanium or non-magnetic stainless steel. These types of drill collars are used in situations where traditional magnetic steel drill collars can interfere with sensitive downhole instruments, such as magnetic resonance imaging (MRI) tools.

Non-magnetic drill collars are typically used in high-precision drilling operations where accurate measurements of formation properties and other downhole parameters are critical. The absence of magnetic interference from the drill collars can improve the accuracy and reliability of the measurements taken by downhole tools.

Non-magnetic drill collars are often more expensive than traditional magnetic steel drill collars, due to the specialized materials and manufacturing processes required. However, their use can help to reduce the risk of measurement errors and improve the efficiency and accuracy of drilling operations in certain circumstances
