Oil recovery efficiency can be increased by applying the enhanced oil recovery (EOR) processes, which are based on the improvement of mobility ratio, reduction of interfacial tension between oil and water, wettability alteration, reduction of oil viscosity, formation of oil banks, and so forth. This book describes the different EOR methods and their mechanisms, which are traditionally used after conventional primary and secondary processes. The present scenario of different EOR processes, at both the field application stage and research stage, is also covered. Further, it discusses some of the recent advances in EOR processes such as low-salinity water flooding, the application of nanotechnology in EOR, microbial EOR, carbonated water injection, etc. Features:Comprehensive coverage of all enhanced oil recovery (EOR) methodsDiscussion of reservoir rock and fluid characteristicsIllustration of steps in design and field implementation as well as the screening criteria for process selectionCoverage of novel topics of nanotechnology in EOR and hybrid EOR method and low-salinity waterfloodsEmphasis on recent technologies, feasibility, and implementation of hybrid technologiesThis book is aimed at graduate students, professionals, researchers, chemists, and personnel involved in petroleum engineering, chemical engineering, surfactant manufacturing, polymer manufacturing, oil/gas service companies, and carbon capture and utilization.
