Insights and Methods for 4D Reservoir Monitoring and Characterization (SEG Distinguished Instructor Series No. 8) covers the application and impact of 4D monitoring for the oil and gas industry, along with some requirements, modeling, and acquisition techniques for ensuring good data and using them to diagnose various reservoir production effects and to update reservoir simulation models. The treatment is designed to provide an understanding of basic underlying principles for specialists in all geoscience disciplines and their managers. The book, based on the SEG/EAGE 2005 Distinguished Instructor Short Course, also treats recently emerged techniques. Key lessons are that nearly all models and predictions without reservoir monitoring are likely to be wrong and that 4D monitoring can be much more than a repetition of conventional 3D surveys. Better ways are available to measure small production differences sensitively. (DISC on DVD, 754A, is also available.)
