A specific type of Cement Logging based on the analysis of the decay and arrival time of the induced acoustic impact.
There are three major types of Acoustic Cement Bond Logging:
| Cement Bond Logging (CBL) |
| Variable Density Logging (VDL) |
| Radial Cement Bond Tool Logging (RBT) = Cement Map |
Modern tool designs combine all three in one housing.
The tool normally includes three components:
| 1 | Acoustic transmitter |
| 2 | Near receiver located at 3 ft away from transmitter and consists of few segment receivers to pick up radial distribution of acoustic response (RBT) and integral response (CBL) |
| 3 | Far sensor located at 5 ft from transmitter and records the full waveform (VDL) |
