Salinity-related tests furnish direct indication of rock-water interaction. They allow evaluation of damage induced by drilling, completion, workover, and injection fluids. [[:file:rock-water-reaction-formation-damage_fig1.png|Figure 1]] illustrates results of a laboratory experiment to evaluate the reaction to reservoir rock with a proposed injection brine. [[Permeability]] was reduced to 20% of its original value after exposure to 20 pore volumes of proposed injected brine. Good reservoir management requires that injected volumes equal produced volumes; therefore, reduced injectivity results in reduced hydrocarbon production rates.
