Introduction to Acoustic Fluid Logger
With Pressure Pulse Gas Gun and Microphone
The Acoustic Fluid Logger collects fluid level measurements on pumping oil and gas wells. Our
intent is to allow consistent and accurate fluid level measurements without the need for any specialized
knowledge. Therefore, there are no computers to operate. There is no need to make any filter adjustments.
Our unit is rugged and operates largely on its own. With the push of a button, you have a fluid level.
The Acoustic Fluid Logger, in an advance over other fluid level devices, first stores its signals to
memory and then prints them out to tape. This allows a very detailed view of the wellbore to be stored
real time and then printed out. A simple count of tubing collars finds the distance to the liquid.
Included in the Acoustic Fluid Logger system is the Pressure Pulse Gun and Microphone. The
Pressure Pulse Gas Gun is available in both the 1,500 psi and 3,000 psi versions. The stainless steel gas
gun shoots a pulse of compressed CO² down the annulus of the well; the return signals are received on the
internal microphone and transmitted to your recording device via the microphone cable. The gun consists
of a volume chamber, a valve assembly and a microphone. Both gas guns allow the use of either an
implosion or an explosion shot, so on higher pressure wells, the use of an external gas source is not
required. The gun may be easily disassembled for maintenance. Adapters are available for all gas guns, to
allow connection to any wellbore.
All of the products at Sage Technologies are the result of years of field experience and technical
innovation. In addition, our technical and training staff and our full repair shop stand behind each piece of
equipment.

Included with your Acoustic Fluid Logger System
•Acoustic Fluid Logger
10 rolls thermal paper
Acoustic Fluid Logger System manual
Wall-mount battery charger
Microphone cable
•Pressure Pulse Gas Gun and Microphone
Charge hose for CO²bottle
2 ½ pound CO² bottle, empty
4" Spanner wrench

Other tools needed in the field
•CO² bottle must be filled with gas to provide the shot. Generally, the bottle should be weighed
when empty, then filled to the specified product weight of the bottle. The standard bottle is a 2.5
lb. CO² bottle.
•11-point dividers for echo calibration
•Adjustable wrench for the CO² hose and wellhead valves
•9/16" wrench for the fittings

Shooting the pumping fluid level
Quick start instructions
•Close the backside valve on the well before set-up.
•Connect the Pressure Pulse Gas Gun to the annulus of the well behind the backside valve, using
the spanner wrench provided.
•Open the backside valve to pressure up the gun.
•Push the gun’s shuttle valve into the load position.
•Charge up gas gun chamber by feeding pressure into the gun from the CO² bottle through the
charge hose to achieve a positive differential pressure. To do this, stab the charge hose into the
“Fill” valve labeled on the side of the gun.
•Shut in the casing flow line valve, so the shot will not go down the flow line.
•Connect the microphone cable to both the Acoustic Fluid Logger and the Pressure Pulse Gun.
•Turn on the Acoustic Fluid Logger unit and verify that the header prints as the paper advances.
Press 4 and then C. This puts the unit in the ¼ compressed mode that makes the tape ¼ of its
usual length. This allows you to quickly see if you have a valid fluid level without waiting for a
long tape printout.
•Press START to put the unit in the standby mode. The header will advance a small amount and
the unit will wait for you to shoot the gun.
•Shoot the Pressure Pulse Gun by pushing shuttle valve in the “Fire” direction. The unit will start
printing.
•Let the printer run until you have seen a valid fluid level kick. Press STOP at this point to stop
the tape.
•Inspect the resulting compressed tape chart for valid fluid and readable collars.
•If valid fluid is found, push Print to get an exact reprint of the same fluid level in its full-length
form.
•Otherwise, follow the above procedures to shoot another shot on the well.
