Liu, Z. (author), Zhao, Ge (author), Brewer, Mark (author), Lv, Qichao (author), Sudhölter, Ernst J. R. (author)With the increasing demand for efficient extraction of residual oil, enhanced oil recovery (EOR) offers prospects for producing more reservoirs’ original oil in place. As one of the most promising methods, chemical EOR (cEOR) is the process of injecting chemicals (polymers, alkalis, and surfactants) into reservoirs. However, the main issue...review 2021
