Solving Direct Problems of Electrical Resistivity Tomography for Media with High-Conductivity Irregular-Shaped Heterogeneities by an Example of a Multiple Well Platform

Abstract

Under consideration is a multiple well platform where the metal pipes of various diameters that are located above and below ground act as interferences together with boreholes with metal tubing. The sought-for objects of study are the thawing zones located near the boreholes. Numerical calculations of direct problems are performed by the nodal finite element method implemented in the author’s software package for solving the problems of electrical resistivity tomography.
