Abstract: Methods, systems, devices, and products for evaluating a fluid. Methods include introducing a sample comprising the fluid to a solvating fluid at a point in a chamber associated with the instrument at a first time to create a heterogeneous admixture; measuring concentrations of each of a plurality of components in the admixture at a plurality of distances from the point in the chamber at, at least one additional time later than the first time, each of the plurality of distances being non-zero; and estimating a relative concentration for each of the plurality of components in the fluid by extrapolating the relative concentration of each of the plurality of components in the sample at the point at the first time using the measured concentrations in the admixture at the plurality of distances.

Abstract: A pressure pulse is initiated from the wellbore into the fractured formation where the frac fluid brings into the fractures a material that is responsive to the pressure pulse alone. Alternatively, or with a combination with a wellbore pressure pulse, well conditions such as time exposure and temperature can initiate local pressure pulses within the fracture with the result being signal generation of an electromagnetic signal that is measured with multiple sensors to allow triangulation of the location of the fracture extremities. The material can be a piezoelectric material that responds to the pressure pulse or ferromagnetic materials that similarly respond to the pulse to create the measured signals. The material can be delivered initially with the frac fluid or at different points in time during the fracture operation. Different materials with unique signal generating characteristics can be used to get a clearer picture of the extent of the fracture.

Abstract: Methods, systems, devices, and products for evaluating a downhole fluid in a borehole intersecting an earth formation. Methods include using ultrasonic irradiation to produce sonoluminescence from cavitation in a volume of the fluid; obtaining spectral information from measurement of the sonoluminescence with a light-responsive device; and estimating a parameter of interest of the fluid from the spectral information. The parameter may be a composition of the fluid or concentration of: i) at least one chemical element in the volume; i) at least one molecular element in the volume. Methods include deconvolving a response spectrum by using one or more separately determined standard spectra, or estimating the parameter of interest using spectral lines represented by the spectral information. Methods may include using an optically transparent ultrasonic transducer to produce the cavitation at the interface of the transducer, with optically transparent ultrasonic transducer between the interface and the light-responsive device.

Abstract: Methods, systems, and devices for determining a parameter of interest of downhole fluid using an acoustic assembly comprising a single solid acoustic transmission medium having a face immersed in the downhole fluid. Methods include using characteristics of a plurality of acoustic pulse reflections from a solid-liquid interface at the face of the solid acoustic transmission medium to estimate the parameter of interest in near real-time. The characteristics may comprise a corresponding reflection amplitude and the corresponding unique angle of reflection for each acoustic pulse reflection. Methods may include generating a two dimensional data set from measured characteristics, generating a curve by performing data fitting on the two dimensional data set, and using the reciprocal slope of the curve to estimate the parameter of interest. Methods may include estimating time-dependent values for the parameter of interest substantially continuously while the acoustic assembly is on a single logging run in the borehole.
