We will discuss the design of nano/microparticlesthat are capable of active movement through oil reservoirs. These can be deployedin a reservoir through injection in the form of aqueous suspensions. They moveactively by utilizing ion gradients in the reservoir and collect at theoil/water interface. The observed active chemotaxis is caused by thediffusiophoretic force on the particles combined with osmotic flow. The particlesare able to navigate around obstacles in seeking the source of the ion gradient.Further, their small dimensions allow them to migrate through narrow channels. Thefactors that govern the active, directed particle movement will be described indetail.
