Overview

Well Test Analysis for Multilayered Reservoirs with Formation Crossflow introduces the fundamentals of well test analysis of a multilayered reservoir with formation crossflow. The effects of reservoir parameters on wellbore pressure and flow rate are examined, as is a proper method that has been established to analyze well test data that leads to better determinations on the reservoir parameters for each layer of the reservoir. Focusing on multilayer models for data analysis, this reference explains the reasons for the existence of single-phase crossflow in multilayer reservoirs, exploring methods to establish them and presenting practical applications to utilize and implement for today’s more complex reservoirs. Aiding in better well testing operations and models, this book is a one-stop solution for today’s reservoir and production engineer, helping them understand every layer of their reservoir.

He has about 25 years of reservoir engineering experience with a focus on well test analysis and production data analysis. He has published over 60 papers in peer-reviewed journals and SPE conferences. He is an author of 4 books published by Elsevier, including Advanced Production Decline Analysis and Application, Well Test Analysis for Multilayered Reservoir with Formation Crossflow, Dynamic Well Testing in Petroleum Exploration and Development, among others. Chengtai Gao (deceased) graduated from the mathematics department of mechanics from Peking University. He had more than 40 years of industry experience in well testing, reservoir description, and production and reservoir engineering. He worked for Sichuan, Jianghan, and Changqing oil field early in his career and specialized in reservoir engineering and application software development. He was a visiting scholar at the University of Houston and Rice University in 1981-1983 where he specialized in well test analysis for multilayered reservoir with crossflow. He joined the Xi'an Petroleum University where he specialized in gas reservoir engineering aspects of low-permeability gas reservoir. He had published over 30 papers in peer-reviewed journals and SPE conferences.
