    摘要: A system for manipulating electric fields within a microscopic fluid channel includes a fluid channel with an inlet and an outlet to support fluid flow, at least one controllable electric field producer that applies a non-uniform and adjustable electric field to one or more regions of the fluid channel, one or more sensors that measure one or more parameters of a fluid flowing through the fluid channel, and a controller with hardware and software components that receives signals from the one or more sensors representative of values of the one or more parameters and, based on the parameter values, drives one or more actuators to adjust the electric field produced by the plurality of electric field producers. A complex fluid including at least two components flows through the fluid channel, where at least one of the at least two components comprises particles controllable by the non-uniform and adjustable electric field.

    摘要: A method is provided including calculating a first property vector indicative of physical properties derived from a digital image of a first rock sample; determining a set of one or more similar rock samples by calculating a value indicating a similarity between the first rock sample and second rock samples based on the first property vector and second property vectors associated with the second rock samples; selecting a list of fluid additives based on existing enhanced fluid recovery efficiency values associated with the similar rock samples; performing, for each of the fluid additives, a simulation of a flow of fluid through a digital model of the first rock to determine a simulated enhanced fluid recovery efficiency value for the respective fluid additives; and outputting an optimal fluid additive for the first rock sample based at least in part on the calculated similarity values and simulated enhanced fluid recovery efficiency values.
