From the Lab to the Reservoir Simulator: How do we optimally select SCAL relationships?

The first part of the presentation gives an introduction and overview of the challenges of optimally selecting SCAL relationships for dynamic reservoir simulation.

Secondly, after briefly reviewing capillary pressure concepts, the universal Modified Carman-KozenyPurcell (MCKP) model is introduced, followed by examples of applying QC to lab data using the MCKP model. It is then shown how the MCKP model is used to predict the optimal relationships for reservoir simulation model layers. Similarly as for capillary pressure, the third part of the presentation briefly reviews relative permeability concepts, followed by introducing the so-called two-phase Modified Carman-Kozeny (2p-MCKP) model, a universal formulation. After QC of lab data, it is shown how to determine optimal relationships as simulation input. A comparison is also made with the Modified Brooks-Corey model.

Finally, a brief demo is given of the Integrated Core Data Modelling System (ICDMS), demonstrating lab QC functionality and prediction of SCAL relationships. The one-hour lecture is followed by Q/A period (up to half an hour). The lecture would be predominantly of interest to reservoir engineers but other subsurface disciplines may also find it informative.
