Availability of Crude oil in India is tend to be light and sweet. The generalproduction value per barrel per day is 880, with specific gravity varying from32 API to 38 API.This text covers all forms of enhanced oil recoverytechniques with both fundamental principles and specialized applications.Students in all areas of fluid flow in permeable media and professionalresearchers can benefit from the unified approach to EOR based on commonfirst principles, conservation of mass, momentum, and energy. Mathematicaltechniques based on phase behavior and the method of characteristics (MOC)are fundamental to the text.
