  • Patent number: 11420214
    Abstract: Measurement of in-situ petroleum reservoir wettability at the current salinity and at different salinities and water compositions. That data may be used to derive the crude oil acid and base equilibrium constants for the oil-surface adhesion reaction that control wettability. These constants may be used in quantitative models of the reservoir wettability. This procedure produces an accurate description of reservoir wettability and identifies the specific water chemistry that will optimize in-situ wettability and, in turn, oil production.

  • Patent number: 11422079
    Abstract: A fluid is received into a sample tube. A processor causes an energy to be applied to the sample tube to induce vibration in the sample tube at a resonant frequency of the sample tube containing the fluid. The processor stops the supply of energy to the sample tube. The processor monitors an amplitude of the vibration of the sample tube as the amplitude of the vibrations diminish over a period of time. The processor uses the monitored amplitude to calculate an RF of the sample tube containing the fluid. The processor uses the calculated RF to calculate the viscosity of the fluid.

  • Patent number: 11415457
    Abstract: The present invention provides a vibration sensor, which comprises a circuit board having an accommodating space. A sensing assembly is disposed in the accommodating space. A recess for magnet sliding is disposed in the sensing assembly. Dispose a magnet in the recess and then dispose a coil layer on an arbitrary side or both sides of the sensing assembly. Furthermore, a lubricating layer is coated on the recess. Alternatively, the recess can be a vacuum structure or a hollow cross-sectional structure for reducing the friction between the recess and the magnet. Alternatively, the coil layer can be coated with a protective layer or multiple layers can be stacked. Without increasing the area of the sensor, the sensing on the variation of magnetic flux can be improved. Accordingly, the vibration sensor according to the present invention can achieve wideband detection of vibrations.
