The central role that Reservoir engineers play in a field's development and planning, cannot be underestimated. Recommending, the most appropriate and most cost effective reservoir depletion schemes has a great impact on a field's and ultimately a company's profitability. If done correctly, it will result in a windfall for the company but if done incorrectly or haphazardly, it will result in financial disaster. Advanced Reservoir Engineering, 2nd Edition provides reservoir engineers with valuable insight into the tools, techniques and science of efficient oil recovery even in the most difficult fields. Reorganized for ease of use and with 40% new information, this new edition represents a 50% update over the previous edition. The main objective of the book is to continue to provide practicing engineers and engineering students with an understanding of day-to-day reservoir engineering operations and problems and how to maintain and solve them. Concise and readable, this new edition begins with the fundaments to provide those new professionals a firm foundation of in the methods and techniques. Chapter one, which once dealt with the theory and practice of transient flow analysis and well testing, is now changed to deal exclusively with well testing. The theory and practice of transient flow analysis moved to a more appropriate section of the book. The author has added five new chapters, Reservoir characterization and Up-scaling, Miscible WAG Flood, Enhance Oil Recovery, Reservoir Management and Optimization, and Reservoir Simulation. In addition, the author has added a simulations code chapter. Assist engineering and other personnel to solve operating problems. Develop plans for oil and gas field drilling, and for product recovery and treatment. Maintain records of drilling and production operations. Confer with scientific, engineering, and technical personnel to resolve design, research, and testing problems. Write technical reports for engineering and management personnel.
