Abstract
A method for estimating interval travel time of an Earth formation using an acoustic well logging instrument having a plurality of spaced apart acoustic transmitters and acoustic receivers includes measuring travel time between a transmitter and a receiver for substantially all possible combinations of each of the plurality of transmitters and each of the plurality of receivers. Each of the possible combinations includes a common depth interval of the Earth formations. The method then include determining at least one statistical measure of center of the measured travel times.
