Abstract
An acoustic logging tool may comprise a center load carrying pipe, a receiver module connected to the center load carrying pipe, one or more transmitter modules connected to the center load carrying pipe, and one or more mass modules connected to the center load carrying pipe.
Claims20
A method comprising:
- disposing an acoustic logging tool into tubing, wherein the acoustic logging tool comprises:
- a center load carrying pipe;
- one or more transmitter modules connected to the center load carrying pipe;
- a cover over each of the one or more transmitter modules configured to rotate based on an azimuthal change;
- one or more mass modules;
- and
- a void positioned beneath each of the one or more mass modules, wherein each void is defined by an interior circumferential portion of each mass module and an exterior circumferential portion of the center load carrying pipe.
4 more elements
A through tubing cement evaluation (TTCE) method comprising:
- disposing an acoustic logging tool into at least one pipe, wherein the acoustic logging tool comprises:
- a center load carrying pipe;
- a receiver module connected to the center load carrying pipe;
- one or more transmitter modules connected to the center load carrying pipe;
- a cover over each of the one or more transmitter modules configured to rotate based on an azimuthal change;
- one or more mass modules connected to the center load carrying pipe;
- and
- a void positioned beneath each of the one or more mass modules, wherein each void is defined by an interior circumferential portion of each mass module and an exterior circumferential portion of the center load carrying pipe,
- transmitting a first waveform on a first transmitter modules into the wellbore;
- receiving a first reflected waveform with a receiver on the receiver module;
- transmitting a second waveform on a second transmitter module;
- receiving a second reflected waveform with the receiver on the receiver module;
- transmitting an in-phase waveform from the first transmitter and the second transmitter;
- receiving a reflected in-phase waveform with the receiver on the receiver module;
- and
- detecting changes in cement thickness along the at least one pipe and in azimuthal directions, with the reflected waveforms.

A through tubing cement evaluation (TTCE) method comprising:
- disposing an acoustic logging tool into tubing and/or layers of pipe, wherein the acoustic logging tool comprises:
- a center load carrying pipe;
- a receiver module connected to the center load carrying pipe;
- one or more transmitter modules connected to the center load carrying pipe;
- a cover over each of the one or more transmitter modules configured to rotate based on an azimuthal change;
- a void positioned beneath one or more mass modules, wherein each void is defined by an interior circumferential portion of each mass module and an exterior circumferential portion of a center load carrying pipe;
- transmitting one or more waveforms from a transmitter on the one or more transmitter modules into the wellbore;
- receiving one or more received waveforms with a receiver on the receiver module;
- and
- detecting changes in cement thickness along the tubing and/or the layers of pipe, in azimuthal directions, with the one or more received waveforms.
