Abstract
Data received from a sonde in a borehole is enhanced by first measuring the relative travel time of a signal transmitted from the sonde and reflected from an area in the wall of a borehole. This measurement is repeated for a plurality of angles in a horizontal plane. From this plurality of travel times a best fit ellipse or circle is calculated and the travel times are correlated with the best fit ellipse or circle to provide corrected travel times and to determine the eccentricity of the sonde in the borehole. The corrected travel times are displayed as images to indicate the detailed shape properties of the borehole.
