Nanoparticles offer a way of controlling oil recovery processes that is unmatched by any current or previous technology. They also offer a means of interrogating small-scale physics that is also unparalleled by prior work.
In the recovery of hydrocarbon, the success of nanoparticles depends on the ability to put them in the right place in a reservoir and to be sure that they transport effectively. Emplacement and transport of nanoparticles through permeable media are the subject of this work. The hypothesis is that nanoparticles can be made to flow through permeable media and that these flows can improve oil recovery. The testing step involves making fundamental measurements on the stability of nanoparticle dispersions, many treated to alter the wetting state of phases, the effect of these dispersions have on conventional measurements of the wetting state of fluids with polished surfaces, and finally the transport of dispersions through permeable media. The testing part lies in a concurrent theoretical program that ranges in scale from first principles and molecular dynamic simulation, to modeling of surface potentials, to larger-scale modeling of flow through permeable cores.
