Fines migration in reservoirs is a serious problem because it gives rise to several problems in hydrocarbon production. Several methods have been proposed and applied to manage this problem but some have failed, some have been ineffective while others consolidate wellbore formations. Rendering formation fines immobile by attaching them to the formation matrix is the best option in controlling migrating fines in reservoir formations. There are indications that the presence of certain nanoparticles in the formation can prevent fines migration by fixing them to the formation.

This project therefore investigates the fines trapping capacity of nine nanoparticles in sand packs. The ability of nano treated sands to retain the clays they contain at high flow rates of low salinity water capable of moving fines was examined. The effect of hydrocarbons on the performance of these nanoparticles and other conditions that affect ce their performances were studied. The best performing nanoparticles and the ideal dispersing fluids that aids in accomplishing this task were determined. Experimental results show that dispersing the right kind of nanoparticles in reservoir formations can control fines migration thereby preventing the primary and secondary problems caused by unconsolidated reservoir formations. Field application of this technique will in addition optimize hydrocarbon production and flow assurance.
