Dynamic Well Testing in Petroleum Exploration and Development, Second Edition, describes the process of obtaining information about a reservoir through examining and analyzing the pressure-transient response caused by a change in production rate. The book provides the reader with modern petroleum exploration and well testing interpretation methods, including their basic theory and graph analysis. It emphasizes their applications to tested wells and reservoirs during the whole process of exploration and development under special geological and development conditions in oil and gas fields, taking reservoir research and performance analysis to a new level.
This distinctive approach features extensive analysis and application of many pressure data plots acquired from well testing in China through advanced interpretation software that can be tailored to specific reservoir environments.
- Presents the latest research results of conventional and unconventional gas field dynamic well testing
- Focuses on advances in gas field dynamic well testing, including well testing techniques, well test interpretation models and theoretical developments
- Includes more than 100 case studies and 250 illustrations-many in full color-that aid in the retention of key concepts

Zhuang HuiNong, a professor and senior engineer, graduated from Peking University in 1962. He took part the research of development program in its early stage of Daqing Oilfield after graduation and then since 1965 he served in Shengli Oilfield and was interested in oil/gas well test. In 1980's took charge and operated interference tests and pulse tests in an oilfield in carbonate reservoir successfully; during this period he invented the interpretation type curves for interference well test in dual porosity reservoirs and applied these type curves in field practice; took charge of research of downhole differential pressure gauge and applied these gauges in data acquisition in fields and consequently won the invention award from China Nation Science and Technology Committee and was present the First International Meeting on Petroleum Engineering in Beijing in 1982,and his paper was published in the JPT. Since 1990 he served Research Institute of Petroleum Exploration and Development of CNPC, was concerned with the exploration and development of several large- or medium-scale gas-fields in China and has been doing dynamic performance research in about recent 20 years. Now is serving SPT Energy Group Inc. as its chief geologist. He has been devoting himself to dynamic performance analysis and well test for more than 40 years.

Since he graduated from Daqing Petroleum Institute in 1989, Yongxin Han has worked in RIPED and specialized in pressure transient analysis, production data analysis, and dynamic gas reservoir description. He participated in the exploration and development of several large- and medium-scale gas fields in China and completed more than one thousand gas well intervals dynamic performance study over the past 28 years. He holds a BS degree in Reservoir Engineering from Daqing Petroleum Institute of China, MS and PhD degree in Reservoir Engineering from China University of Geosciences (Beijing). He has co-published 6 books and over 30 papers in peer-reviewed journals and conference presentations about well testing and gas reservoir evaluation and development.
Dr. Hedong Sun received his PhD degree from Xi'an Jiaotong University in 2004. Since 2004, he has been a Research Engineer in Research Institute of Petroleum Exploration and Development (RIPED)-Langfang Branch, which is the R&D center of China National Petroleum Corporation (CNPC).
Hedong has over 18 years of reservoir engineering experience with a focus on well test analysis and production analysis. He published over 40 papers in peer-reviewed journals, and two Chinese books.
