Abstract
Methods for treating subterranean wells involve treating fluids that contain water and a plurality of water dispersible nanoparticles. The nanoparticles may be nanocellulose, rod-like nanoparticles, nanotubes or halloysite or combinations thereof. The water dispersible nanoparticles form one or more aggregates that plug formation pores and may control fluid flow into the formation as well as fluid flow from the formation into a wellbore.
