Special core analysis (SCAL) measurements are conducted in the laboratory to measure flow parameters such as relative permeability, capillary pressure and residual oil saturation. These data are typically used in oil field engineering as input in numerical simulations to predict field behaviour over many years, essential in field development planning.An important problem in the interpretation of the laboratory data is that during relative permeability measurements a strong interference exists with the capillary forces. In the lab these forces play a role that is much different from what occurs on the scale of the field. As an example: the residual oil saturation may appear in the lab to be some 10 to 15 saturation units higher than these really are. Vice versa, during capillary pressure measurements, the relative permeabilities interfere.To unravel this interference, simulations of the experiments are necessary. Very few simulators, however, are capable to simulate flow experiments on the small scale of the laboratory. The presentation will highlight how DuMuX has been adapted to SCAL experiments, including both flooding and centrifuge measurement techniques. Also, simulations will be presented, demonstrating how DuMuX has been used to study experimental issues in capillary pressure and resistivity measurements with the so-called porous plate technique. Finally, a web-based user interface to DuMuX will be presented.
