Methods and systems for logging a wellbore having a casing using ultrasonic logging are described. Traditional ultrasonic logging involves using a piezoelectric transducer that is spaced from the inner surface of the casing by a least a distance referred to as the 'far-field' distance. Logging in the “far-field,” as traditionally done, avoids destructive interference. The methods and systems described herein allow logging in the “near-field.” Logging in the near-field using the described methods and systems overcomes several difficulties associated with acoustic logging, particularly in attenuative, dispersive, and deviated environments.
