SCOTON's Array Noise Tool (ANT) uses an array of highly sensitive wide-band acoustic sensors to detect sound produced downhole by fluid movement.
The tool employs a set of innovative differential measurements to enable excellent rejection of unwanted noise such as "road noise" produced while the tool is moving in the wellbore. The sensor array also allows propagation-direction processing to further extract weak fluid movement sounds from behind multiple pipes.
HOW IT WORKS?
By coupling both differential sensors with array processing this tool can acquire accurate measurements while logging up or down. This saves time and improves effectiveness in any leak detection applications.
