Oil recovery efficiency can be increased by applying Enhanced Oil Recovery (EOR) process which is based on improvement of mobility ratio, reduction of interfacial tension between oil and water, wettability alteration, reduction of oil viscosity, formation of oil bank and so forth. This book describes different EOR methods and their mechanisms which are conventionally used after conventional primary and secondary processes. Present scenario of different EOR processes both at the field application and research stages is also covered. Further, it discusses chemical EOR recovery, nanotechnology in EOR, low salinity water flooding, ECBM and enhanced recovery techniques for shale oil and gas.

Features:

• Comprehensive coverage of all the Enhanced Oil Recovery (EOR) methods.
• Discusses reservoir rock and fluid characteristics.
• Illustrates steps in design and field implementation as well as the screening criteria for process selection.
• Covers novel topics of nanotechnology in EOR and Hybrid EOR method and Low salinity waterfloods.
• Emphasis on the recent technologies, feasibility, and implementation of hybrid technologies.

This book is aimed at graduate students, professionals, researchers, chemists, personnel involved in petroleum engineering, chemical engineering, surfactant manufacturing, polymer manufacturing, oil/gas service companies, carbon capture and utilization.
