ABSTRACT
The production of oil from porous environment has always been characterized with different problems which have so many implications on the overall oil recovery from the reservoir and also on the quality of the formation. Fines particles creation and migration due to the flow of fluids contribute immensely to the damage experienced inside the reservoir. This research focused on the application of copper and iron oxides nanoparticles dispersed in four different fluids, via; diesel, ethanol, high salinity brine and diesel+ethanol blend before soaking the sand used for the simulation of the porous media, for the purpose of fixating of these fines particles (causes of formation damage) in pore spaces and most especially in fluid flow paths. The effluents results generated due to the fluid flow experiments conducted indicate that the two nanoparticles (copper oxide and iron oxide) have the ability to fixate migrating fines particles in reservoir sands porous media. Also, the use of sands in porous media simulation retained more migrating fines particles with copper oxides and iron oxides nanoparticles and both nanoparticles dispersed in ethanol and diesel+ethanol fluids recorded high level performance when compared to high salinity brine. High salinity brine creates an environment that encourages the creation and migration of fines due to the chemical imbalance introduced when flow fluid commenced in the reservoir.
