  • Publication number: 20190293825
    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.

  • Patent number: 10288764
    Abstract: A method of estimating one or both of compaction or subsidence of a subterranean formation with gravity measurements. The free air gradient at surface is measured and compared with gravity measured in a borehole that intersects the formation. At a later point in time, values for gravity are re-measured, differences between the measured values at the initial point in time, and the later point in time are estimated. The differences are used to estimate the compaction or subsidence. A gravimeter can be used for measuring gravity, markers in the formation can be used in conjunction with the gravimeter.

  • Patent number: 10281413
    Abstract: Examples of nano-level evaluation of kerogen-rich reservoir rock are described. A micro-scale beam is formed from kerogen-rich reservoir rock. The beam has reservoir rock and kerogen, which has polymeric properties. A maximum dimension of the micro-scale beam is at most 1000 micrometers. A mechanical experiment that includes a tension test or a compression test is performed on the micro-scale beam. The mechanical experiment is imaged using a scanning electron microscope (SEM). A material parameter of the kerogen in the micro-scale beam is determined based on results of the mechanical experiment and images obtained responsive to the imaging. The material parameter includes a behavior of the kerogen in response to the mechanical experiment. The behavior of the kerogen can be used to determine, among other things, the energy required to break kerogen in a kerogen-rich shale to improve hydraulic fracturing efficiency.
