Abstract: An apparatus for determining properties of an uncharacterized downhole fluid. The apparatus comprises an oscillation driver circuit comprising an amplifier having an output and an input, a feedback loop between the output and input of an amplifier or a logic gate, an electromechanical resonator disposed within the feedback loop such that a the resonator is driven by the oscillation driver circuit, wherein a resonant frequency of the resonator defines an oscillation frequency of the oscillator circuit, and a switch device for causing the oscillator circuit to stop driving the resonator, which thereby enables observation of a decay rate of the oscillation of the electromechanical resonator within the uncharacterized fluid. The electromechanical resonator is enclosed in a conductive layer to protect the resonator against capacitive effects of the downhole fluid.

Abstract: Systems and methods include a computer-implemented method for performing real-time measurements of drilling fluid in a well. A driver and a reference are monitored for responses by a measurement controller of a system for measuring fluid flow. The driver is configured as a driving electromechanical resonator for contacting the drilling fluid. The reference is configured as a reference electromechanical resonator for contacting the drilling fluid. The reference is of a similar construction as the driver and is in contact with the drilling fluid in a substantially same way. Real-time measurements are performed by the measurement controller based on information received from the driver and reference. A viscosity and density of the drilling fluid are determined based on the real-time measurements. The similar construction of the driver and reference enables mitigation of environmental sensitivities of the driver and reference, enhancing fluid property sensitivities to physical properties of the drilling fluid.

Abstract: An apparatus for measuring a viscosity of a fluid is disclosed. The apparatus includes a Parylene coated quartz tuning fork for immersion in the fluid and an electronic circuit to excite a vibration of the Parylene coated quartz tuning fork and measure one or more vibrational parameters of the Parylene coated quartz tuning fork. A computer processor is configured to determine a non-Newtonian viscosity from the vibration of the Parylene coated quartz tuning fork based, at least in part, on a Stokes flow hydrodynamic model. The computer processor is coupled to a memory for storing a calibration curve to determine a Newtonian viscosity of the fluid from the non-Newtonian viscosity of the fluid.

Abstract: A method and device are described for making in situ measurements of the density and viscosity of downhole fluids at subterranean wells. An oscillator circuit is deployed in the well comprising an amplifier, a feedback loop, and an electromechanical resonator. The electromechanical resonator is a component in the feedback loop of the oscillator circuit, and has a resonance mode that determines the frequency of the oscillator circuit. The electromechanical resonator is also in contact with the fluid such that the density and viscosity of the fluid influence the resonant frequency and damping of the resonator. The frequency of the oscillator is measured by a microcontroller. In one embodiment, the oscillator circuit periodically stops driving the electromechanical resonator such that the oscillation decays and the rate of decay is also measured by the microcontroller. The density and viscosity of the fluid are determined from the frequency and rate of decay of the oscillation. This measurement technique provides a faster response time to fluid changes than is possible with conventional measurement methods, and the fast response time opens up new applications for downhole viscosity and density measurements, including determining PVT characteristics, phase diagrams, and flow rates.
