sonoecho

Downhole fluid level survey

 

The Leutert sonoecho™ meters the fluid level in the casing of a pumping well. This embedded fluid level recorder makes it easy to find and calculate accurate fluid level data. Its main components are: A field handheld data acquisition unit with a 5” display, a gas gun, and a powerful diagnostic software.

The gas gun sends a gas pressure pulse down the annulus of the well. The pressure pulse echoes from each collar and the fluid as it travels down the well. These echoes are detected by an internal microphone within the gas gun and recorded by the sonoecho handheld unit. The sonoecho™ picks the fluid level automatically and shows it on the display.

The software allows the user to generate fluid level reports, including screen shots of graphs and complete fluid level data on the computer. The clearly arranged data archive including a trend graphic allows access to all measurements at a glance. Reports may be printed, saved as data files or transmitted electronically as PDF files. All data files may be stored as raw data to Excel.
