Application of Smart Fluids
• Designing specific hydrophobic or hydrophilic character into
such smart fluids, through the use of novel organic chemistry
on the surface of high-surface-area functionalized
nanoparticles, will significantly alter the mode of operating
and organizing water floods and surfactant floods.
• Moreover, by tailoring the responsivity of these smart fluids,
they can be used either to block or to increase the porosity and
tortuosity of the formations where they are injected.
