Measurement artefacts due to the interference of relative permeability and capillary pressure (as will occur in any SCAL flow measurement) may lead to residual oil saturations that are 10 saturation units higher than the true residual oil saturation. Simulations of the experiments have proved to be an excellent tool to unravel that interference. Also, simulation of SCAL flow experiments has been very successful for a reconciliation of seemingly contradicting results that may come out of different flow experiments on the same core plug. Therefore, there is significant business value in interpretation by simulation.
The simulation technology as applied on the scale of oil and gas reservoirs is well advanced, but the application of simulations on the scale of the core plug is still relatively immature. Shell’s SCAL simulation technology can be shared as a contribution to the advancement of SCAL measurement technology. SCORES is a full-fledged SCAL flow simulator that provides simulations free of charge.
The three major experimental techniques, i.e. the UnSteady State (or Welge) technique, the Steady-State and the Centrifuge technique, are handled with one common “look and feel”.
