CBL Amplitude (5 ft Spacing) (CBL5)

This is the name of a log measured along a well bore (a well-log). The code CBL5 is a unique identifier to recognize this particular log and can be found in any (ASCII) log files provided by the logging company. The official name for this log is 'CBL Amplitude (5 ft Spacing)'. This log is not used too often in the industry.

This log displays readings of the measure of acoustic wave amplitude used for cement bond evaluation.

In general this log thus reflects units of the acoustic amplitude (A measure of the maximum departure of an acoustic wave from the average value).

So basically this is a measure of the extent or range of a property; especially, the maximum departure of a wave from its average value.

This log usually has the unit 'Electric Potential'. This is the measure of Voltage

Data for this log is produced by a tool that uses a acoustic logging technique and can be used to investigate the bond strength of the cement job. Similar logs are listed below:
