Injection of chemicals - associated with a chemical EOR – typically involves the suspensions of sub-micronic particles of the injected chemicals – during its transportation from injection well into spatial locations far away from the injection well. These sub-micronic chemical particles flows through the complex pore geometries of a petroleum reservoir, during which, there is also a finite possibility of the transported chemical particles getting adsorbed over the solid grains, resulting from van der waals / electrostatic attraction.
If so, will it be feasible to comfortably up-scale the captured physical details on the transportation of the injected chemical particles; and the way, these chemical particles access the solid grain surfaces (retention) during its transportation along these complex pores – at the molecular-scale – to a (macroscopic-) scale, where Advection-Dispersion Equation (ADE) remains applicable?
Can we expect the details of the associated molecular-scale adsorption kinetics to get reflected in breakthrough curve analysis?
Whether MRI or NMR or confocal microscopy would be able to capture the sorption kinetics (where the adsorption rate remains different from the desorption rate) for a range of fluid flow rates associated with a petroleum reservoir?
