3.4.4 Running Sensitivity Analysis on the Tank Model
Once at the end of history matching we have selected a model in terms of OIP and
various drive mechanisms, it is important that we do some sort of analysis on the
figures we have arrived at check our confidence in these figures. This is allowed by
doing a sensitivity analysis on the model. In sensitivity analysis what we do is that we
try to see how sensitive is our model to the change in parameters that we have fixed
by history match.
If we go to the main menu and select History Match | Sensitivity the following
screen appears. In this case we want to study the effect of changing the OIP place
only. We are trying to see the effect of changing it between the values of 180 and
250.
