Acoustic Leak Flow Analyser

GOWell’s Acoustic Leak Flow Analyser (ALF) is a memory tool used to carry out various well diagnostic studies including Well Integrity Evaluation, Production Performance and Reservoir Monitoring. This device measures Acoustic Spectrum within the range of 8 Hz to 60,000 kHz with very high frequency resolution.

‍
The tool uses very sensitive acoustic sensor to be able to measure sound produced downhole by either gas or liquid flow. Measurements are taken over a wide frequency range, enabling a very effective way of leak detection a well as detection of various kinds of gas, water, or oil flow, including flow behind the pipe.

Features

• Ability to detect flows through multiple tubulars

• Ability to distinguish flow behind pipe from flow inside pipe

• Combinability with other logging tools to provide a complete well evaluation in a single run

• Slim tool design allowing safe and easy deployment through the smallest completion tubing and restrictions.

• Compliant to NACE MR0175/ISO 15156-2015

• Multi-tool stackable to accelerate acquisition
