A 2 wt% lignosulfonate solution was injected for 10 days as part of the preflush in this project. Results of the analyses of two observation well samples were interpreted for the effect of lignosulfonate on sulfonate adsorption and process performance. Even though the evidence was ambiguous, we concluded that the low-cost lignosulfonate preflushing was beneficial to surfactant flooding.
