In these processes, the surfactant is included in the composition with the acrylamide polymer friction reducer, or it is introduced separately into the process. The performance of low-cost polyacrylamide friction reducers can be boosted with a small proportion of certain readily available nonionic surfactants. The inventive compositions are effective in high-salinity environments, and their performance can sometimes exceed that of more-expensive salt-tolerant friction reducers, thereby reducing fresh water demand and enabling greater utilization of produced water.
