Abstract
A method and system for geosteering may generate a misfit function using a spline function. The misfit function may be used to accurately map errors or differences between TVD-based measurement data for one or more reference wells and MD-based measurement data collected during drilling of a subject well, in order to accurately determine a stratigraphic location of the subject well.
