Abstract

It is very important to get a reliable result in transient electromagnetic (TEM) inversion. Most of the traditional inversion algorithms are based on the assumption that resistivity changes smoothly underground, through which we cannot get clear geological interface. With the purpose to represent clear boundary with resistivity discontinuity, this paper applies Minimum Gradient Support (MGS) Functional to TEM inversion. Through the three-layer model test, this method is proved more accurate in determining sharp electrical interface compared with smoothest model inversion. Also, this algorithm does not rely on the starting model and the iterative process is stable.
