  7. Abstract:
  8. Fines migration due to their severe problems during oil production must be controlled. They cause the productivity decline due to their deposition near the well bore. Recently, application of nanotechnology in fine migration control has been much attended in both experimental and field case investigations. The main goal of the present study is to find out the ability and different effects of Nano particles (NPs) such as concentration, types and even the magnetic sensitivity to retain fines migration. In order for this, two groups of tests were conducted by engineered porous media. In this study, for the first time, an experimental setup was designed and constructed to investigate the control of fines migration in the presence and the absence of magnetic field using NPs which are sensitive to it. Three different types of NPs, SiO2, Al2O3, and Fe2O3 were utilized to perform the experiments. Also, the effect of salinity and flow rate on fine migration was investigated through analysis of the effluent samples by turbidity meter apparatus. To evaluate experimental data, by using the DLVO theory, the total interaction energy was calculated. The forces which act on particles in retention and detachment such as drag, lift, gravity and electrostatic forces were calculated by using the mathematical relations. Also by using 1D flow in deep bed filtration theory some of parameters, like as filtration coefficient was extracted. The results confirm that, in general SiO2 NPs has the best performance to retain the fines in comparison with others. On the basis of experimental results in the presence of a magnetic field, Fe2O3 could control and mitigate fines migration. Also, increasing in salinity has the drastic effect to control of fines
