This book deals with complex fluid characterization of oil and gas reservoirs, emphasizing the importance of PVT parameters for practical application in reservoir simulation and management. It covers modeling of PVT parameters, QA/QC of PVT data from lab studies, EOS modeling, PVT simulation and compositional grading and variation. It describes generation of data for reservoir engineering calculations in view of limited and unreliable data and techniques like downhole fluid analysis and photophysics of reservoir fluids. It discusses behavior of unconventional reservoirs, particularly for difficult resources like shale gas, shale oil, coalbed methane, reservoirs, heavy and extra heavy oils.

Dr. Raj Tewari is Custodian Reservoir Engineering and Group Technical Authority at Petronas, Malaysia. During his more than three decades long career in the oil and gas industry, he has worked in various companies, namely ONGC, GNPOC, Sudapet and Petronas, as a practicing reservoir engineer. He started his career in ONGC’s Institute of Reservoir Studies in the 1980s where he was involved with reservoir characterization and numerical simulation, oil and gas field development planning and EOR laboratory studies. After 12 years he moved to Mumbai as Manager Reservoir and contributed to the redevelopment of the giant carbonate field, Mumbai High. His
responsibilities included water flood management and identification of IOR/EOR initiatives for the field. He moved to North Africa in early 2000 to lead the Reservoir Engineering at GNPOC, a joint venture company. During this period he was responsible for field development planning (FDP) studies and reservoir management and surveillance of GNPOC fields, producing at plateau rate of 300 kbopd. Dr. Tewari joined Petronas in 2007 and since then has been actively involved in redevelopment studies of number of major fields incorporating EOR. In 2010-2011 he joined the national oil company of Sudan as Custodian PE and was involved with cyclic steam stimulation and steam flood EOR projects. He has extensive experience in light and viscous oil fields development and management, reservoir characterization and simulation, EOR and reservoir management. He is actively involved in EOR studies and R&D projects in Petronas. He has conducted training courses on Fluid Characterization, Rock Properties, Advance EOR and Reservoir Engineering. He was visiting professor to Khartoum University and also teaches in UTP on specialized topics. Dr. Tewari holds a Ph.D. degree in Physics from Banaras Hindu University, India. He has published nearly 50 papers in journals and conferences. He has been chairperson and technical committee member for a number of SPE Technical workshops and conferences. Dr. Tewari is Industry Advisor to University Technology Petronas (UTP), Malaysia. He has been awarded SPE Asia Pacific Technical award for Production and Operation in 2015.
Abhijit Dandekar is Professor and Chair of the Petroleum Engineering program at the University of Alaska Fairbanks, where he has taught since January 2001. Before joining UAF, he was an assistant research professor at the Technical University of Denmark. In the summer of 2002 he also worked as visiting faculty at the University of Petroleum Beijing, P.R.C. He has also been a visiting professor at the African University of Science and Technology (AUST) in Abuja, Nigeria and visiting professor at the University of Witwatersrand, Johannesburg, South Africa (as Fulbright specialist). He holds a B.Tech degree in chemical engineering from Nagpur University, India and a Ph.D. degree in petroleum engineering from Heriot-Watt University, Edinburgh, UK. Prof. Dandekar has authored more than 80 papers and a widely adopted textbook on Petroleum Reservoir Rock and Fluid Properties and he is also the editor for Emerging Trends and Technologies in Petroleum Engineering book series (Taylor & Francis). He has supervised more than 30 graduate students and conducted several funded research projects primarily in the area of PVT and SCAL. In 2014 he received the SPE Distinguished Membership and Fulbright Specialist awards. In 2015 he was the recipient of the SPE Western North America Region Distinguished Achievement Award for Petroleum Engineering Faculty. Over the last 16 years he has contributed to numerous SPE activities, is a current petroleum engineering program evaluator (PEV) for ABET and has served on six visits.
Jaime Moreno is a reservoir engineer with focus on EOR R&D, instructor, and a principal engineer for Schlumberger. His strong expertise in field development and reservoir characterization with an emphasis in EOR was developed through a 20- year career, which started with Schlumberger’s Holditch Reservoir Technologies in Denver as a simulation engineer working with NFR triple porosity reservoirs in the Gulf of Mexico, South America and unconventional reservoirs in continental USA. Throughout his career he has worked as lead technical engineer in several field projects, including field development planning, in USA, Malaysia, Australia, Middle East and North Africa. Starting in 1998 he held a combined role in R&D for EOR, concentrating on screening (patented
technology), pilot planning, monitoring and surveillance. He has taught internal and external courses on EOR and compositional modeling. Mr. Moreno holds an Msc degree from the Colorado School of Mines in USA, has published nearly 20 papers in journals and conferences and has been a technical committee member of several SPE applied technical workshops and conferences in the Asia Pacific region.
"Overall, this is a well written and well-presented book that is worthy of inclusion on a personal bookshelf or on a library bookshelf."
