Claim Text:
1. A method for obtaining a composite image of a subterranean formation, the method comprising: measuring impedance data within a subterranean formation; determining first formation impedivity data by performing a first formation impedivity determination process; determining second formation impedivity data by performing a second formation impedivity determination process; combining a portion of the first formation impedivity data with a portion of the second formation impedivity data to determine a combined formation impedivity data; and generating the composite image using the combined formation impedivity data; wherein measuring the impedance data includes measuring the impedance data at a first frequency, measuring the impedance data at a second frequency that is lower than the first frequency, and measuring the impedance data at a third frequency that is lower than the second frequency; wherein the first formation impedivity data is based on a component of the measured impedance data orthogonal a downhole fluid impedance and the first formation impedivity determination process includes: combining the first composite orthogonal data with the third orthogonal data to obtain the first formation impedivity data; and wherein the second formation impedivity data is based on an amplitude of the measured impedance data, and the second formation impedivity determination process includes:
