Abstract:
A technique includes performing first electromagnetic field measurements to obtain a first set of data and performing second electromagnetic field measurements to obtain a second set of data. The first set of data is relatively sensitive to an effect caused by an air layer boundary and is relatively insensitive to the presence of a resistive body. The second set of data is relatively insensitive to the effect and is relatively sensitive to the presence of the resistive body. The technique includes combining the first and second sets of data to generate a third set of data, which is relatively insensitive to the effect and is relatively sensitive to the presence of the resistive body.
