Looking to microwaves
Microwave measurement has typically been limited because it is only accurate in a narrow range of operating conditions, with specific levels of liquid or gas, for example, and the meter must be recalibrated as conditions change.
Researchers from our Exploration and Petroleum Engineering Center – Advanced Research Center (EXPEC ARC) teamed up with colleagues from King Abdullah University of Science and Technology (KAUST). Over seven years they developed a novel, microwave resonance-based multiphase meter able to provide real-time monitoring of water cut and flow.
This meter uses a digital-twin artificial intelligence model to predict flow in the pipe and compare that with our measurements, enabling our meter to automatically tune itself to wide-operating conditions and significantly reduce the need for recalibration.
Using microwaves means the meter is non-radioactive, reducing complexity and safety measures for sites using the device. It is also non-intrusive — the microwaves pass through the fluids inside the non-metallic section of the pipe — and can be used on pipes of different sizes and orientations, without needing to be inserted into the pipe. Unlike some meters, which can be installed only one way up, it can measure accurately in any orientation.
