Special features of fluid level tapes
Seven amplification levels hone the accuracy of fluid tapes
Each time an echo is shot with the Acoustic Fluid Logger, it actually records seven different
representations of the wellbore at the same time. Any or all of these representations can be printed
through the use of the Acoustic Fluid Logger keypad.
Here is an example of a single shot, where all seven representations are printed. Each time you
take a fluid level shot on a well, you have the opportunity to print any or all of these seven tapes, with
seven different amplifications of the signal, through the use of keypad commands. It may help to think of
the seven amplification tapes as looking at the echo through a series of magnifying glasses of increasing
power. If you like a certain amplification better than others, then that tape can be printed first. If you need
to move up or down in amplification, then you can easily do so, without taking another shot on the well.
Remember, the Acoustic Fluid Logger will hold the echo in memory, until the unit is turned off, or until
another shot is recorded.
Following are seven keypad commands that will print the seven possible tapes. Note: It is
assumed that you have an echo in memory – which means that the Acoustic Fluid Logger has been turned
on and the gas gun has taken a shot on a well.
Command: Print
This command prints an overall plot, using the square root of the largest amplitude of the signal.
Command: 1 Print
This command produces minimum amplification of the signal.
