Insights and Methods for 4D Reservoir Characterization

Covers the application and impact of 4D monitoring for the oil and gas industry, along with requirements, modelling, and acquisition techniques to ensure good data acquisition and use in diagnosing reservoir production effects and updating reservoir simulation models; key lessons on measuring small production differences are highlighted.

Insights and Methods for 4D Reservoir Monitoring and Characterization is a recording of the 2005 SEG/EAGE Distinguished Instructor Short Course presented by Rodney Calvert. Catalog #228A is the accompanying DISC book. This course 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. 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.
