Abstract
Disclosed is a method monitoring changes in saturation of a subsurface volume. The method comprises: obtaining observed data of saturation behavior from the subsurface volume over time; using one or more models, obtaining simulated data of saturation behavior from the subsurface volume over time; and transforming each of the observed data and simulated data. The transformation is done such that in each case the data is described in terms of: a front location parameter, wherein a cell of the subsurface volume is attributed a value according to its location relative to a front of the fluid for which saturation is being monitored, and a sweep intensity parameter, wherein a cell of the subsurface volume is attributed a value according to either the observed saturation variation over a time period, or an estimated saturation variation over the time period, finally, a mismatch between saturation behavior in said transformed observed data and saturation behavior in said transformed simulated data over said time period is calculated.
