An impending energy crisis is looming all over the world, which has led to the use of effluents from paper mills for enhanced oil recovery (EOR), CO2 flooding and wastewater treatment by biosurfactants, and the current market demand for cost-competitive and environment-friendly alternatives to synthetic chemicals. This most up-to-date book on petroleum technology provides a comprehensive review of the background and recent advances in the field of petroleum technology and highlights various facets of the fascinating world of upstream, midstream, and downstream petroleum technologies. It comprises 15 chapters, each representing the progress, prospects, and challenges in petroleum research, and focuses on the tremendous progress made by the scientific community in this research field. The book covers in detail EOR processes, reservoir engineering, production operation and optimization, drilling and completion technologies, pipeline transportation and storage, CO2 capture and sequestration, utilization and storage of hydrocarbons, petroleum geology, wastewater management and innovative treatment, petrochemicals and polymers, refining technologies, environmental chemistry, and biochemistry and biotechnology for the petroleum industry.

Subrata Borgohain Gogoi is professor of petroleum technology at Dibrugarh University, India, since 1994, before which she served as technical services engineer at Bongaigoan Refinery and Petrochemicals Limited, Assam. She obtained her MTech in chemical engineering and PhD in petroleum technology. She successfully completed four major research projects as principal investigator (PI), the most prestigious of which was the IndoU.S. 21st Century Knowledge Initiative project with the Department of Petroleum Engineering, University of Louisiana at Lafayette, USA. Currently, she is also working as the Indian PI for three international projects and three national projects funded by the Government of India. Prof. Gogoi is a reviewer for 12 international journals and has authored 1 book. Her current research interests include EOR leading to CO2 sequestration and application of nanotechnology for oilfield-produced water (OFPW) treatment. Her EOR group is engaged in characterising reservoir fluids and rocks for formulating EOR slugs for application in depleted reservoirs, both nationally and globally, and in validating experimental findings of the research through simulation and modelling. Her OFPW group is developing membrane-based treatment technologies and working on bioremediation and the evaluation of the corrosion and scaling potential of OFPW.
