SUMMARY
Waterflooding is an important part of most secondary or tertiary recovery processes during which the injected water, mostly seawater for the case of offshore oilfields, is injected for pressure maintenance, increasing sweep efficiency, and Journal of Petroleum Exploration and Production Technology mobilization of the residual oil when combined with some surface-active agents to change the chemical equilibrium between the rock and fluids. There are some downsides associated with injecting an aqueous phase with dissolved salt content different than that of the in-situ formation brine (Mackay 2003). This chemical incompatibility between the in-situ formation brine . . .
