In a method of processing resistivity log data, two or more resistivity log measurements of differing depths of penetration of an invaded formation are generated. The deepest and shallowest of the resistivity log measurements are combined in accordance with a non-linear combination algorithm that is modulated by a parameter. The value of the parameter used varies in dependence on a comparison between deep and shallow log measurements. The results of the comparison are forward modelled from sample data. A modified log output is generated as a result of combining the deepest and shallowest of the resistivity log measurements in accordance with the non-linear combination algorithm.
