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".
