1. A method comprising:
based, at least in part, on a first set of acoustic measurements of a borehole, generating a first beamforming map;
estimating a first leakage location based, at least in part, on the first beamforming map;
based, at least in part, on a second set of acoustic measurements, generating a set of beamforming maps corresponding to a set of acoustic velocities, each beamforming map of the set of beamforming maps being generated using a different acoustic velocity of the set of acoustic velocities;
evaluating spatial statistics of the set of beamforming maps against one or more criteria to identify which of the set of beamforming maps indicates a most prominent leakage location; and
updating the first estimated leakage location based, at least in part, on the identified beamforming map.
