    Abstract: Methods and systems are provided that determine at least one fluid parameter for a drilling fluid and a particular drilling operation, wherein the at least one fluid parameter is selected from the group consisting of: i) a first fluid parameter that relates to shear forces that break apart components of the drilling fluid during the particular drilling operation, ii) a second fluid parameter that characterizes mixing of drill cuttings with the drilling fluid during the particular drilling operation, and iii) third and fourth fluid parameters that characterize normal stress in the drilling fluid during the drilling operation. The methods and systems can evaluate one or more of these fluid parameters to determine a drilling fluid formulation that optimizes the drilling fluid for effective transport of drill cuttings. Methods and systems are also provided that evaluate one or more of these fluid parameters to determine operating parameters that optimize a drilling operation for effective transport of drill cuttings using the drilling fluid.

    Abstract: Sag propensity of a fluid can be determined by applying an oscillatory strain at an amplitude in excess of a linear region and below a yield strain of the drilling fluid. This may include use of medium amplitude oscillatory shear (MAOS), from which an elastic modulus of the fluid is determined. The elastic modulus may be determined over time, from which a time to reach maximum elastic modulus can be determined. The time to reach maximum elastic modulus is then converted or correlated to a drilling fluid sag propensity for the drilling fluid either in absolute terms or in relation to base or comparison fluids. Such an evaluation can be performed using a torsional resonance device in which the oscillatory strain is controllable so as to be maintained relatively constant during the measurement.

    Abstract: The present disclosure provides systems, tools, and methods for enhancing a measurement of a property of a solid body or fluid. The systems, tools, and methods may involve an electromagnetic measurement tool that includes a transmitter configured to transmit electromagnetic energy, a receiver configured to receive the electromagnetic energy, and a metamaterial element comprising a negative refractive index. The metamaterial element may focus the electromagnetic energy. The electromagnetic tool may be placed adjacent the solid body or fluid, electromagnetic energy may be transmitted via the transmitter, and the electromagnetic energy may be received with the receiver to measure a property of the solid body or fluid.

    Abstract: Interfacial tension between first and second immiscible liquids is determined using a device in which entrance and exit channels are connected by a cavity with wider cross-section. A flow of the first liquid enters the cavity as a jet and breaks into droplets within the cavity. Passage of a droplet through the exit channel feeds back to perturb the jet entering the cavity. An alternating signal applied to a heating element perturbs the incoming jet and is progressively scanned over a frequency range which includes the system's resonant frequency (frequency of droplet formation with no signal to the heating element). A bandwidth of frequency is observed in which the frequency of droplet formation is phase locked to the frequency applied to the heater. The ratio of resonant frequency to this bandwidth is a measurement of the interfacial tension between the two liquids.

    Abstract: A heat transfer device, such as a heat exchanger, has dimensions and flow speed such that Reynolds number for the flow is in a range from 1 to 1000. The device uses a working fluid which is in a state of elastic turbulence. This enhances transfer of heat to or from the working fluid. In some embodiments the fluid is an emulsion with a disperse phase which changes between liquid and solid so that its latent heat of fusion contributes to the amount of heat carried by the working fluid.
