Edge detection of subsurface structures in magnetic data in presence of remnant magnetization

Author

Abstract

Edge detection of subsurface structures is an important goal of magnetic data interpretation. To achieve this goal, the reduction to the pole (RTP) is used to locate magnetic anomalies over the structures causing these magnetic anomalies. The RTP cannot be used in the presence of remnant magnetization. In this situation, amplitude of magnetic anomaly, analytic signal, E and R transforms are used. In this paper, we apply the Canny edge detector over amplitude of magnetic anomaly for edge detection in magnetic data. The results indicate that this edge detection method is suitable when the remnant magnetization exists in the magnetic data.
