Abstract
Current magnetic inspection is performed only on new parts for directional tools. This holds true in particular for tool collars. In addition, the minimum distance between the directional magnetometers and specific regions of potential magnetic interference are defined such that the risk for magnetic interference is controlled. Placing the magnetometers closer to those regions holds cost saving potential in capitalization and operations cost, but it also requires improved QA processes on magnetic properties during inspection. The equipment used for the inspection is large and costly and therefore does not exist in many locations of the world. We propose simplified devices that are capable to measure magnetic contamination at collar connection threads and related tong areas on the surface with lower device cost.
