Abstract

Magnetic prospecting is one of the most widely used geophysical prospecting methods in the exploration of fuel resources including crude oil and coal. In magnetic prospecting data process, anomaly separation is an important step. A method for computation of regional magnetic anomaly (RMA) using a third-order isoparametric element with 12 nodes is developed. In this technique, regional and residual magnetic anomaly can be separated fully using given magnetic data even in the case of irregular-shaped survey area.
