Mathematical Modeling of Fines Fixation in the Sandstone Cores Soaked by MgO Nanofluid

Formation damage in oil reservoirs as a result of fines migration is a major reason for productivity decline. Fines loosely<br>attached to the pore surface are in the equilibrium with the pore fluids. These particles start to flow when the equilibrium<br>state is disturbed which, may end up in permeability reduction in porous media. Different solutions have been suggested to<br>prevent detachment of fines from surface such as acidizing, ionic clay stabilizer, polymers and etc.
