Inversión unidimensional de datos de polarización inducida para medios de contraste pequeño en resistividad
Main Article Content
Abstract
The interpretation of induced polarization soundings for low rcsistivity contrast media is posed in terms of a linear integral equation. Two solutions of this equation are prcsentcd: (a) an anal y tic solution by means of integral transforms, and (b) a numerical solution using linear programming. The first establishes that the inverse problem has, at least IÍn principie, a unique solution, and the second allows the construction of models from field data. The construction of models is illustrated assuming zero resistivity contrast, for which thc integral equation is exaet, and it is extended to cases that involve resistivity variations. Applications of the algorithm to field data are also included.
