Acoustic Fluid Logger AFL V
The Sage Acoustic Fluid Logger AFL V is a reliable and efficient wireless solution for determining the distance from the wellhead to the fluid level in the casing annulus of oil and gas wells. Utilizing advanced acoustic technology, the system delivers fast, accurate, and non-invasive fluid level measurements that are essential for well diagnostics and production optimization. Designed for field use, the AFL V combines robust hardware, wireless data acquisition, and powerful diagnostic software in a compact, easy-to-use system. Reports can be edited, printed, and saved as data files, or distributed electronically as PDF documents. Raw measurement data can also be exported to Excel for further analysis.
Technology Overview
An Acoustic Fluid Logger operates by generating a pressure pulse that travels down the annulus of the well. As the pulse propagates downward, it reflects from tubing collars and the fluid level. These returning echoes are detected by an integrated microphone and converted into precise fluid level data. The Sage AFL V features:
-
A Pressure Pulse Gas Gun with an integrated microphone
-
A wirelessly operated data acquisition unit
-
Bluetooth data transmission to your Windows based laptop, tablet, Android or Apple phone.
Advanced Diagnostic Software
The AFL V diagnostic software automatically converts acoustic signals into a clear and easy-to-interpret chart with automatic fluid level identification. Key software capabilities include:
-
Automatic fluid level detection
-
Comprehensive fluid level reports with screenshots and detailed measurement data
-
Trend and overlay functions for long-term well performance evaluation
-
Structured data archive for quick access to historical fluid levels.

Pressure Transducer Option with AFL V
-
To calculate gas afterflow in the casing or the wellbore an Accurate Pressure Transducer (APT) completes a pressure casing buildup before the fluid level shot. The APT attaches to the top of the Pressure Pulse Gas Gun at the quick connect. It wirelessly connects to your computer.
-
Before the fluid level shot is taken, the Accurate Pressure Transducer completes a pressure casing buildup, which enables calculation of the gas afterflow in the casing or in the wellbore.
-
The AFL V software now calculates the gas free fluid level, (the percentage of true liquid in the fluid column) which delivers the producible commercially relevant fluid level depth.
