摘要： 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.

摘要： A drilling fluid manager creates a multi-dimensional drilling fluid additive model and interpolates changes in a drilling fluid based on a combination of additives. The interpolations are inverted to determine the amount of additives based on measurements of drilling fluid properties. As fluid is returned to the surface, drilling fluid parameters are measured. A difference between the measured fluid parameters and setpoint fluid properties and the inverted interpolations are used to determine the amounts of each additive.

摘要： An apparent viscosity of an aqueous polymer composition used in a polymer flood may be determined by generating a relative permeability interpolation computer simulation model that is associated with a capillary desaturation function and that interpolates relative permeability curves for a coreflood experiment, validating the relative permeability interpolation computer simulation model using experimental data generated from the coreflood experiment using a water flood performed at a plurality of incremental flow rates on a core plug, determining an interpolated relative permeability to water for the aqueous polymer composition using experimental data generated from the coreflood experiment using a multi-phase flood with the aqueous polymer composition, and determining an apparent viscosity of the aqueous polymer composition from the interpolated relative permeability to water. The determined apparent viscosity may then be used to run a simulation to model the flow of the aqueous polymer composition.

摘要： 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.
