摘要： Methods for purifying a fluid may include injecting an impure fluid comprising carbon dioxide and at least one impurity into a first subterranean aquifer. The impure fluid may be circulated within the first subterranean aquifer for a period of time sufficient to separate at least a portion of the at least one impurity from the carbon dioxide to produce an at least partially purified fluid comprising the carbon dioxide, the at least partially purified fluid having a lower concentration of the at least one impurity than the impure fluid. The at least partially purified fluid may be removed from the first subterranean aquifer, wherein at least a portion of the at least one impurity remains entrained within the first subterranean aquifer.

摘要： A method for demonstrating the efficacy of using electrical current in an Electrical Improved Oil Recovery (EIOR) application includes circulating fluid through a microfluidics cell having first and second electrodes, applying a voltage across the first and second electrodes, determining the behavior of the fluid under the effect of the applied voltage, and correlating the determined behavior to a reservoir of interest. The method may include deriving operational parameters from the correlation and operating the reservoir of interest in accordance with the operational parameters, and may include visualization and characterization of enlarging pore throat for enhancing permeability and oil mobilization.
