1. A method for identifying a leak for dynamic logging, comprising:
recording one or more acoustic signals as raw data;
estimating a Stoneley wave slowness;
separating a Stoneley wave into an up-going Stoneley wave and a down-going Stoneley wave;
estimating an amplitude of the up-going Stoneley wave and the down-going Stoneley wave;
identifying a difference between the amplitude of the up-going Stoneley wave and the down-going Stoneley wave;
summing the amplitude of the up-going Stoneley wave and the down-going Stoneley wave to form an amplitude summation curve; and
identifying a location of the leak.
