This course aims to encompass advanced techniques and workflows for history matching geological and reservoir models in both conventional and unconventional reservoirs. It covers manual and assisted history matching methods, as well as inverse modeling techniques, examining the advantages and disadvantages of each approach. The course incorporates various types of production and history data, including pressure or rate transient tests, tracer tests, multiphase production history, and interpreted 4D seismic information. Field examples will be presented to demonstrate the current state of the art and highlight limitations. Additionally, the course explores the utilization of history matched models to optimize reservoir development and management strategies, such as optimal infill well placement, rate optimization, well allocation for enhanced sweep efficiency, and well completion optimization in unconventional reservoirs. The course combines theoretical discussions, practical applications, and computer exercises using publicly available software to provide participants with hands-on training on applicable workflows using commercial software.
