The critical interstitial velocity at which permeability reduction due to fines migration is initiated can be determined in laboratory tests. These tests simulate the effect of high flow rates that exist near the wellbores of both injection and production wells. Muecke<ref name=pt05r118>Muecke, T. W., 1979, Formation fines and factors controlling their movement in porous media: Journal of Petroleum Technology, v. 31, p. 144–150., 10., 2118/7007-PA</ref> discusses factors controlling fines movement. These include fluids flowing, fines [[wettability]], and interfacial forces.
