Course Description
This course is designed to cover techniques to incorporate production data into high-resolution reservoir models using conventional and fast flow simulation techniques such as streamline models. Both assisted history matching and automatic history matching techniques will be covered and pros and cons of the methods will be discussed. The production data can be in the form of pressure transient test, tracer test, multiphase production history or interpreted 4-D seismic information. Field examples will be presented to illustrate the current state of the art and limitations. PC-based computer programs will be used to provide hands-on experience with the various techniques.
