Subsurface Microwave Surveillance Technology

The Subsurface Microwave Surveillance Technology, also known as MMS (Measure Monitor Surveillance) Waveguide Technology, is a pioneering system developed by Welldata Subsurface Surveillance Systems for monitoring and measuring subsurface anomalies. This innovative technology utilizes microwave signals of known frequency and bandwidth that are transmitted through structures such as wells, pipelines, and tubing, acting as waveguides.

The core principle behind this technology is microwave reflectometry, where the microwave signals propagate through the waveguide and reflect off any anomalies or features, such as liquid-gas interfaces, scale buildup, or structural changes. These reflected signals are received at surface-located instrumentation and analyzed using W3S Max-Well integrated analytical software.

One of the key advantages of this technology is its ability to provide accurate and repeatable data without the need for traditional in-well instrumentation, thereby reducing well-entry risks, operational expenses, and environmental impact. The technology can detect liquid levels, bottom-hole pressures, liquid loading, scale formation, and real-time in-flow/out-flow measurements in tubing sizes ranging from 25mm to 450mm or more.

The system incorporates passive surface-mounted microwave sensors, low-power requirements (24VDC, 20 milliamps maximum signal power output), and a range of over 1000 meters, depending on tubing size and conditions. Additionally, the Max-Well software compensates for thermodynamic variations, ensuring accurate data analysis, and enables remote data access through a MODBUS-configured software platform.
