A method of screening a plurality of fluids for an effectiveness in enhancing oil recovery comprises introducing a petroleum hydrocarbon into a plurality of separate fluid channels to saturate the fluid channels, each of the fluid channels having a porous structure configured to represent a condition of an earth formation; injecting a plurality of aqueous based fluids into the fluid channels; imaging the fluid channels to provide a plurality of images; analyzing the images to determine amounts of the petroleum hydrocarbon remain in the fluid channels after injection of the aqueous based fluids; and determining an effectiveness of the aqueous based fluids in forcing the petroleum hydrocarbon out of the fluid channels.

Utilizing microfluidics as a rapid screening technology for enhanced oil recovery

An embodiment of a method of evaluating fluid trapping in an earth formation includes injecting a water-based fluid into at least one fluid channel fabricated on a substrate, the at least one fluid channel having a pore structure configured to represent a condition of an earth formation. The method also includes injecting oil into an inlet of the at least one fluid channel until at least a selected amount of the injected oil exits the channel, imaging the fluid channel and determining an amount of remaining fluid in the fluid channel after injection of the oil, the remaining fluid being an amount of the oil and/or an amount of the water-based fluid, and estimating a proportion of the total volume of the fluid channel occupied by the remaining fluid to determine an amount of fluid trapping in the pore structure. The method further includes analyzing the amount of fluid trapping.
