Some Survey and Interpretation Problems on IP Method

Problems of IP mining exploration are analyzed and solutions presented in the paper. The dipole-dipole array configuration is considered as a symmetrical array in terms of the reciprocity principle. In the paper, is demonstrate that the IP/Resistivity configurations of the anomalies in pseudosections depend from the location of transmitting and receiving dipoles related to target, there are left C1C2-P1P2 and right P1P2-C1C3 arrays. IP physical modeling and field surveys have demonstrated that exist differences between real medium and mathematical models. In IP sections of mathematical models, anomalies remain open in the depth. It is due to the fact that in used mathematical formulas, the IP chargeability is considered as a linear phenomenon. The use for the inversion of formulas based on the linear IP phenomenon implies errors, which may be comparable with the instability of the inversion itself. To achieve the quality of IP surveys, it is necessary to well evaluate the non-linear character of IP phenomenon. An accurate interpretation of data with dipole-dipole array should consider the information on dipoles orientation on the survey line. The same recommendation is valid for the inversion interpretation. IP Realsection represents the best solution for the representation of the underground anomaly medium.
