Today, there is much discussion about the dangers of water contamination to human health. Numerous environmental studies and projects are undertaken and accomplished every year. Despite this, most developing countries continue to struggle with the inefficient administration of their water supplies. The problem of contaminated water and the method of purifying it are both extremely challenging, and much of the research done on the topic is probably not up to the mark to cope with the current environmental issues. Henceforth, appropriate methods need to be developed and established to improve water quality. Through this book, the authors aim to provide a framework for understanding the causes, pollutants, and potential remediation for water contamination. The text provides up-to-date reviews of the latest research and practises for removing contaminants from water through green methods.

This book focuses on the use of nanoemulsion in enhanced oil recovery, along with a brief information about the emulsion and its types and different physico-chemical properties used to analyse the efficiency of the emulsions and nanoemulsions. The author discussed about the nanoemulsion, classification of emulsions and nanoemulsion and use of nanoemulsions in petroleum industry. A special attention has been laid on nanoemulsion and its advantages over commercial product, physico-chemical properties like emulsification, interfacial tension and wettability alteration study as a screening criteria for application in EOR. Given this content, this book offers an assessment for the undergraduate and postgraduate students of petroleum and chemical engineering along with the researchers working in the field of EOR. It is a subject of interest for oil and gas industry professionals.

This book focuses on the use of natural surfactants in enhanced oil recovery, providing an overview of surfactants, their types, and different physical–chemical properties used to analyse the efficiency of surfactants. Natural surfactants discuss the history of the surfactants, their classification, and the use of surfactants in petroleum industry. Special attention has been paid to natural surfactants and their advantages over synthetic surfactants, including analysing their properties such as emulsification, interfacial tension, and wettability and how these can be used in EOR. This book offers an overview for researchers and graduate students in the fields of petroleum and chemical engineering, as well as oil and gas industry professionals.

This book addresses unconventional hydrocarbon resources in India and the prospects for their exploitation. Each chapter focuses on a particular unconventional resource, including gas hydrates, coal bed methane and shale, while the book as a whole takes into account the government’s projections concerning these resources. The book provides readers with essential information on the nation’s energy requirements, methods of exploiting its available unconventional resources, and their contribution to meeting India’s energy requirements. It also addresses the various geological conditions that are necessary for the exploration of these resources, and enables readers to understand the challenges that need to be overcome. Its logical, clearly structured chapters make the book an ideal starting point for readers interested in unconventional energy resources. It will especially benefit undergraduate and graduate students in the field of Energy Engineering, as well as academic researchers and industry professionals seeking an overview of the status quo of unconventional hydrocarbon resources in India.
