DrilLife Group uses the technology to help operators to identify and pinpoint costly wellbore leaks by analyzing sound waves that describe flow patterns in the formation and casing.
The service employs an array of hydrophones that measure sound in and around the wellbore. Based on the measurements and analysis, this service has the ability to determine which an annulus or completions system is leaking in real time. Unlike other ultrasonic detections technologies the ACX service stores high-definition data internally, which can be downloaded at surface and sent for advanced processing. This data allows engineers to develop 2D flow illustrations to further characterize the leak, reducing uncertainties. It saves time by providing a continuous mode to quickly identify areas with possible leaks in the wellbore. In some cases, this enables more precise flow rate and phase estimation at leak locations. The ACX service can be utilized in a variety of environments, including mature fields and unconventionals.
