  • Publication number: 20200158612
    Abstract: Disclosed is a system and method for determination of the viscoelastic properties of a viscoelastic substance based on the type of non-mechanical forces which drive the viscoelastic substance inside a channel. These forces may comprise capillary, gravitational, electric, magnetic, or any other type where neither a pump nor any relative velocity between solid surfaces is needed to induce the transport of fluid medium. As a result, the design of the system remains simple, and the system is capable of yielding results devoid of noise produced by mechanical forcing. The present disclosure a general analysis describing extraction of viscoelastic properties by observing flow-systems driven by any non-mechanical means, including capillary force and electro-osmotic force. Such time-dependent penetration depth may be recorded by optical, electrical or mechanical means and may further include the use of a computing device.

  • Patent number: 10651656
    Abstract: A control system and method include a control strategy and a UDE (Uncertainty and Disturbance Estimator)-based controller incorporated into the control strategy to achieve proportional load sharing for parallel-operated inverters. The UDE-based controller regulates the reactive power against the output generated by a reactive power reference unit according to the load voltage to generate the amplitude of the control voltage. The conventional droop method regulates real power to generate the phase of the control voltage. As a result, the model uncertainties (e.g., parameter drifts and uncertain output impedance), and system disturbances (e.g., fluctuating DC-link voltage and load change) can be estimated and compensated for accurate load sharing.

  • Publication number: 20200088016
    Abstract: Methods for optimization of liquid oil production by huff-n-puff in shale reservoirs to achieve an improved (and optimal) oil recovery factor. The process determines and utilizes the optimum huff and puff times, number of cycles and soaking time under practical operation and reservoir conditions. The huff time in the process is a period so long that the pressure near the wellbore reaches the set maximum injection pressure during the huff period. The puff time in the process is the time required for the pressure near the wellbore to reach the set minimum production pressure during the puff period. Soaking is typically not necessary during the huff-n-puff gas injection in shale oil reservoirs. The number of huff-n-puff cycles is determinable by the time in which the economic rate cut-off is reached.

  • Publication number: 20190376376
    Abstract: Method to generate microfractures by chemical reaction in low carbonate mineral content shale reservoirs in which sulfate acid or persulfate compound (such as ammonium persulfate ((NH4)2S2O8) at a relatively high content) injected into conventional fracturing fluid can react with shale carbonate components resulting in the precipitation reaction of gypsum crystal (CaSO4.2H2O) to occur because an insoluble calcium sulfate (CaSO4) solid is formed. It has been found that expansion stress generated by rapid crystallization in the shale nanoscale pore space can intensively crack shale rocks without additional energy input. Not only does this lead to the formation of much denser secondary microfracture networks, it also can increase SRV by the micrometer-scale gypsum crystals prohibiting these secondary microfracture networks from closure under a normal stress, thereby, improve the efficiency of hydraulic fracturing and hydrocarbon production.

  • Publication number: 20190372609
    Abstract: Disclosed is a system and method for a complex domain radio frequency (RF) frontend, adaptive beamforming can separate the relatively slowly changed waveform delay information required from wideband RF signals, upon which a self-contained beamforming system is implemented with a low-speed baseband. By introducing vector RF multipliers in the frontend of the present invention, the amplitude and phase of RF signals are simultaneously controlled by the real and imaginary parts of complex numbers, such that beamforming algorithms derived in complex domain can be directly applied without any form of transformation. By doing so, the massive use of conventional T/R modules and high-speed baseband devices can be avoided, thus simplifying the realization and decreasing the cost of wideband digital beamforming systems for use in low cost, power efficient beamforming applications.
