Reducing fines migration by use of Nanofluids injection-an experimental study

Formation damage because of fines migration is a major reason for productivity decline. Many studies have characterized fines and their migration effect on permeability reduction. Nanofluids that contain nanoparticles (NPs) show specific properties including a high tendency for adsorption and being a good candidate for injection into the near-wellbore region because of the very small NP sizes. The study indicates that fines could adhere to the matrix grains, hindering their migration, when the porous materials are soaked with nanofluids.
