Abstract
A method for borehole compensation using a single transmitter measurement electromagnetic propagation tool is disclosed. Phase shift and attenuation are measured at each of three positions relative to a measurement depth. The measurements are used to calculate borehole compensation. The method may be used for other single transmitter tools and provides more accurate formation measurement in boreholes having high rugosity and washouts.
