1. A method, comprising:
receiving input parameters and resistivity data for a borehole, wherein the resistivity data is obtained during drilling of the borehole;
generating a set of distribution curves utilizing the resistivity data and the input parameters, wherein the set of distribution curves includes twenty or more distribution curves;
identifying one or more subterranean formation surfaces using the set of distribution curves;
providing directions to a geo-steering system using the one or more subterranean formation surfaces identified via the set of distribution curves; and
geo-steering a drill bit during the drilling according to the directions using the one or more subterranean formation surfaces identified via the set of distribution curves.
