Publication number: 20220299348Abstract: A multiphase flow measurement apparatus includes a tubular, a first microwave resonator, a second microwave resonator, and a coplanar waveguide resonator. The tubular includes a wall formed to define an inner bore configured to flow a multiphase fluid. The first microwave resonator has a first helical shape with a first longitudinal length and is configured to generate a first electric field that rotates. The second microwave resonator has a second helical shape with a second longitudinal length different from the first longitudinal length of the first microwave resonator and is configured to generate a second electric field that rotates. The first and second microwave resonators are mutually orthogonal to each other and cooperatively configured to measure a salinity of the multiphase fluid flowing through the inner bore. The coplanar waveguide resonator is configured to generate a third electric field to measure a flow rate of the multiphase fluid.Type: ApplicationFiled: March 19, 2021Publication date: September 22, 2022Inventors: Muhammad Akram Karimi, Muhammad Arsalan, Atif Shamim

Patent number: 11327000Abstract: An example system is configured to detect saturation levels of a target, such as a core sample of a reservoir, using magnetic fields generated by hydrophilic magnetic nanoparticles within the target. The target contains both a hydrocarbon, such as oil or gas, and a mixture comprised of water and the hydrophilic magnetic nanoparticles. The system includes magnetic field detectors for spatial distribution across a dimension of the target. The magnetic field detectors are configured to detect a magnetic field associated with the hydrophilic magnetic nanoparticles. A data processing system is configured—for example, programmed—to determine a saturation profile of the target based on the magnetic field.Type: GrantFiled: May 21, 2018Date of Patent: May 10, 2022Assignees: Saudi Arabian Oil Company, King Abdullah University of Science and TechnologyInventors: Muhammad Akram Karimi, Muhammad Ayub, Muhammad Arsalan, Atif Shamim
