“…There are many existing WC meters which are being used on the top surface to measure the water produced from a particular well. For example, water and oil can be distinguished based on the difference in their densities [1], infrared absorption coefficients [2] or dielectric properties [3] [4] [5] [6] [7] [8].…”

Water is a by-product of oil extraction process whose amount needs to be determined accurately to optimize the oil production process. Almost 99.9% of the instruments used to determine water content in oil, are installed on the top surface outside an oil well. With the top surface water-fraction or watercut (WC) meters, it is impossible to locate the water producing zones inside the well because oil (and water) is produced from multiple branches inside a well. Ideally, a downhole WC sensor needs to be installed with every branch of the well for better water management. This paper presents a compact microwave based WC sensor which is compatible with an existing downhole system. Sensor consists of a λ/4 open stub based spiral resonator. The stub is printed on a dielectric core residing in the center of a metallic pipe. The stub is fed with a microstrip feedline which has a dedicated ring-shaped ground plane. Mixture flowing between the central core and the metallic pipe changes the dielectric properties and the resonance frequency of this uniquely designed sensor. WC sensing phenomenon has been validated both in simulations as well as inside a flow loop with measured sensitivity of over 200%.

Leakages from pipelines are low-probability but high impact events for distributors of crude/refined oil as well as drinking water. Several techniques including geological surveys, fiber optics, acoustics, pressure drop analysis and mass imbalance are in use to detect the leakages. However, all the techniques have their own drawbacks such as low sensitivity, high false alarm rate and process parameter dependencies. Pipe joints, being the most prone to leakages, have been targeted in this paper for real-time leakage monitoring. Instead of relying on indirect indicators such as vibration and pressure drop, we are proposing a new kind of microwave leak detector which can easily be clamped on a joint. The sensor utilizes a uniquely designed stripline ring resonator to detect the change in dielectric properties (caused by leakage) of a 3D printed porous substrate which is sandwiched between the two ground planes of the stripline. Main sensing element has been realized by a combination of 3D and inkjet printing. While protective clamp-style cover has been fabricated using lathe machining, 3-axis milling and wire EDM which not only protects the sensor from environmental effects such as rain but also helps avoiding false alarms. The proposed system has been validated in EM simulations as well as in measurements, which confirm that the system can not only detect the leak event but also can estimate its intensity. The measured sensitivity is better than 0.3mL which is much higher than the existing methods.

“…Real-time monitoring through inline WC sensors allows for efficient reservoir management and production allocation [3]. WC sensors currently available are either costly, heavy, intrusive, severely sensitive to water salinity or incapable of covering the full WC range [3]. Inline detection of water fraction in oil can be done by sensing the differences in viscosity, effective electric permittivity [4], or IR/gamma-ray absorption characteristics of oil/water mixtures [5].…”

Precise measurement of the water fraction in oil is of critical importance in the oil industry. Currently, cost-effective, reliable and compact downhole measurement technologies capable of full range three phase measurements are not available. This paper presents an ultra-low-power, low cost, wireless and non-corrosive resonance sensor based on magnetoelastic technology that has been implemented by an amorphous ribbon and electromagnetic interrogation. The proposed technology enables distinguishing all three gas, water and oil phases with amplitude changes of 75% and 99% and resonant frequency shifts of 0.46 % and 3.88 %, respectively, compared to the gas phase. The response of the sensor enables characterizing the water-cut range from 10% -90%. The addition of a Teflon anti-corrosion layer enables sensor deployment for extended periods of time in harsh environments.
