Fixed gate amplitude in cbl mode (FGAB) |
This is a well log used in the oil and gas industry. You could find this abbreviation FGAB in your log evaluation software or any (ASCII) log files provided by the logging company. The code stands for 'Fixed gate amplitude in cbl mode'. This log is not often acquired after (or during) drilling a well. This log can be used to evaluate the measure of acoustic wave amplitude used for cement bond evaluation. In general this log therefore displays units of the acoustic amplitude (A measure of the maximum departure of an acoustic wave from the average value). Simply said, this is a log that describes the extent or range of a property; especially, the maximum departure of a wave from its average value.This log in unitless. Either the log measurements can not be expressed with a unit (eg. a ratio) or the unit is unknown to us. 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:
