Abstract
A method may comprise disposing an acoustic logging tool into a wellbore, wherein the acoustic logging tool comprises a P-E transceiver. The method may further comprise transmitting one or more acoustic waves from the acoustic logging tool with the P-E transceiver, recording superimposition of first reflection and subsequent reverberations at the acoustic logging tool with the P-E transceiver, and creating acoustic waveforms. The method may further comprise identifying one or more model parameters of the wellbore and deriving a predicted impedance from the one or more model parameters of the wellbore and the acoustic waveform.
Claims20
A method comprising:
- disposing an acoustic logging tool into a wellbore, wherein the acoustic logging tool comprises a P-E transceiver;
- transmitting one or more acoustic waves from the acoustic logging tool with the P-E transceiver;
- recording an acoustic waveform that is a superimposition of first reflection from inner surface of casing and/or subsequent reverberations from the casing with the P-E transceiver;
- creating synthetic waveforms from source pulse and a testing parameter configuration;
- identifying one or more model parameters of the wellbore;
- and
- deriving a predicted impedance from at least the one or more model parameters of the wellbore and the acoustic waveform.
A system comprising:
- an acoustic logging tool disposed in a wellbore, wherein the acoustic logging tool comprises a P-E transceiver configured to:
- transmitting one or more acoustic waves from the acoustic logging tool with the P-E transceiver;
- and
- recording an acoustic waveform that is a superimposition of first reflection from inner surface of casing and/or subsequent reverberations from the casing with the P-E transceiver;
- an information handling system configured to:
- create synthetic waveforms from source pulse and a testing parameter configuration;
- identify one or more model parameters of the wellbore;
- and
- derive a predicted impedance from at least the one or more model parameters of the wellbore and the acoustic waveform.
