Formation damage as a result of fines migration causes drastic reduction of rock permeability; then, retracts hydrocarbon production rate. When the brine salinity which presents in the core reduced to its critical salt concentration (CSC), fine particles initiate the release process. In this study, MgO nanofluid was prepared and its stable sample was characterized based on the transmission electron microscopy analysis. Afterward, stable MgO nanofluid injection into Berea sandstone cores was perform to investigate the effect of nanofluid injection on fines triggering prevention. The obtained results showed significant disparities in permeability ratios between two cores with/without nanofluid treatment. Permeability reduction occurred up to 95% of inchoate permeability for no treatment case which is demonstrated by scanning electron microscopy analysis and MgO nanofluid could lessen fine particles release in the water shock phenomenon and fix them for the case with nanofluid treatment.
