Acoustic Fluid Logger IV

The Acoustic Fluid Logger AFL IV uses your field computer to pick the fluid level in a well and display it on your computer screen. The AFL IV software allows the operator to fine-tune or recalculate fluid level by moving the start of shot, the depth of fluid level, or the event of fixed depth (such as perforations, or a tubing anchor), and then re-examining the resulting data. The software not only calculates the fluid level, but also give you the ability to predict future production. Allowing an operator to use his own portable computer makes the Acoustic Fluid Logger AFL IV both more compact and more affordable than a bulky system with a captive computer. Plus, the software can be installed on your field office and engineering office computers, as well. 

AFL IV - How it works

The Acoustic Fluid Logger IV is straightforward and easy to operate. First, the Pressure Pulse Gas Gun is connected to the wellhead. A microphone cable connects the Pressure Pulse Gun to the Acoustic Fluid Logger IV. A USB cable attaches the fluid logger to the operator’s portable computer.

The Pressure Pulse Gas Gun is charged with compressed gas. When the gun is fired, the echo reflecting from the liquid and the collars is registered by the microphone inside the gas gun and transmitted to the fluid logger, which transfers data to the computer.

The software displays the fluid level test as a graph on the computer screen, and the program calculates the fluid level depth.

Sage AFL software fine-tunes the fluid level

Since no two oil or gas wells are quite the same, the software allows ample room for customization. The Acoustic Fluid Logger IV software produce quick and easy Fluid Level Reports as PDF files. The following screen shots show many of the options available for customizing fluid level reports.

The above graph also shows the click-and-move colored cursors, another feature of the Sage AFL software: 

  • Start of compressed gas shot which begins the fluid level test  (red cursor)

  • Fluid level (blue cursor)

  • Event of fixed depth inside the wellbore, such as a tubing anchor (green cursor).
