Potential methods, such as gravity and magnetic, are extensively used for subsurface exploration of mineral and geothermal reservoirs. In the last five decades, a number of efficient schemes for forward modeling of potential methods have been proposed. In this seminar, I will present a basic review of these forward modeling methods. I will insist mainly on the numerical aspects of the methods. These methods rely on an efficient implementation of an integral solution to the Poisson equation. Because this integral solution does not require matrix inversion, and because the Poisson equation appears in a number of physical phenomena, I will conclude the talk by contemplating the possibility of solving physical problems on implicit subsurface structural models without matrix inversion. The physical problems of interest obviously include gravity and magnetic problems, which are the subject of this talk, but also other problems such as fluid flow in the subsurface.
