Abstract
Chemical enhanced oil recovery (EOR) has become one major topic in oil field development as the conventional oil recovery methods cannot fulfill the increased oil consumption demand. The common chemical EOR methods include polymer flooding (PF), surfactant flooding (SF) and wettability alternation, alkaline flooding, and their combination, such as surfactant–PF, alkaline–SF, alkaline–PF, and alkaline–surfactant–PF. This chapter describes the principles of each chemical EOR method, as well as the characterization and evaluation of commonly used chemical agents, discusses the factors impacting the efficiency of each method, advantages, and disadvantages, and addresses the application limitation and the status of the applications. This chapter also covers the new developments of the chemical EOR technologies and the remaining challenges.
