What is Streamline Simulation?

Streamline simulation technique simplifies the conventional finite difference 3D simulation (FD) into a number of 1D problems by assuming some streamlines or pipes that transport the oil molecules from high pressure zone to low pressure zone. They depict the actual flow-path of fluid molecules within the reservoir.

Because of its simplicity, large reservoir model can be subjected to such simulation techniques with limited computer resources. Or, large number of models or realizations can be analyzed within short period of time. The technique may not give a robust result that can be fully trusted for large scale economic investment decisions. (We have to rely on more reliable and proven techniques of FD simulation). However, it is very good tool for a number of purposes.
An incomplete list is given below:

1. Compare / evaluate the heterogeneity of multiple realizations of geo-model.
2. Assist in upscaling optimization.
3. Identify reservoir continuity and optimize injectors
4. Uncertainty Analysis
