Pros and Cons of Applying a Proxy Model as a Substitute for Full Reservoir Simulations

摘要

A comparative study was made of proxy-modeling methods (also known as surrogate modeling or metamodel-ing) as a computationally inexpensive alternative to full numerical simulation in assisted history matching, production optimization, and forecasting. The study demonstrated the solution-space complexity for different simulation models and the applicability of the proxy models to mimic it. Focus was given to practical aspects of model construction and to limitations of which engineers should be aware.
