Sammendrag
Flow diagnostics are simple quantities that can be derived from basic flow simulations to probe a reservoir model, establish connections and basic volume estimates, and measure heterogeneity in flow paths.
This user guide introduces various types of flow diagnostics, followed by an overview of two graphical user interfaces (GUIs) developed in the MATLAB Reservoir Simulation Toolbox (MRST) that can be used to quickly interrogate an ensemble of model realizations and investigate relative differences in flow patterns between them, prior to running computationally expensive, multiphase flow simulations.
The first GUI enables you to inspect and cross-plot various measures of dynamic heterogeneity as well as simplified estimates of (economic) objectivity functions such as recovery factor and netpresent value for the whole ensemble. The second GUI focuses more on volumetric connections, communication patterns, and timelines for fluid transport within individual models or selected subsets of the full ensemble. It offers much of the same visualization capabilities as the GUI developed for flow-diagnostic postprocessing of multiphase flow simulations.
