Efficient Removal of Magnetic Contamination From Drilling Fluids: The Effect on Directional Drilling

Abstract Magnetic debris in a drilling fluid have significant influence on the ability of to maintain its function. Down hole logging can suffer from poor signal noise ratios. Directional areas close magnetic North Pole, such as Barents Sea, Northern Canada, or Russia, because contamination fluid. particles introduce additional errors surveying compared those normally included ellipsoid uncertainty calculation. On many offshore rigs, there are mounted ditch magnets remove metallic swarf These only coarser swarf. In this project, we use combination strong and flow directors significantly improve performance magnets. This combination, together with proper routines for cleaning magnets, helps clean Through combined it was possible extract more than five times much normal other magnet systems. is verified by comparing efficiencies two rigs extended reach (ERD) wells Sea area. paper, discussed how accuracy directional well position effected various interferences be improved minimal effect measurement while (MWD) measurement.
