Improved Oil Recovery by Surfactant and Polymer Flooding contains papers presented at the 1976 AIChE Symposium on Improved Oil Recovery by Surfactant and Polymer Flooding held in Kansas City. Organized into 18 chapters, the book includes papers that introduce petroleum reservoirs and discuss interfacial tension; molecular forces; molecular aspects of ultralow interfacial tension; the structure, formation, and phase inversion of microemulsions; and thermodynamics of micellization and related phenomena. Papers on adsorption phenomena at solid/liquid interfaces and reservoir rocks, as well as on flow through porous media studies on polymer solutions, microemulsions, and soluble oils are also provided. Significant topics on molecular, microscopic, and macroscopic aspects of oil displacement in porous media by surfactant and polymer solutions and related phenomena are also discussed. The literature cited in this book forms a comprehensive list of references in relation to improved oil recovery by surfactant and polymer flooding. This book will be useful to experts and non-experts in this field of research.
