Abstract
Disclosed is a method of modelling a subsurface volume. History data for one or more parameters over a first period of time is obtained. The first period of time comprises a plurality of schedule periods, each schedule period having associated with it a sampled value of the considered parameter at the corresponding time. A merge error value is attributed to plural pairs of consecutive schedule periods, the merge error value representing a magnitude of the error in a merged value of each parameter over the duration corresponding to a pair of schedule periods being considered, relative to the sampled values for said pair of schedule periods being considered. The pair of schedule periods which have the smallest error value attributed thereto is merged, and the merged schedule period has attributed to it, the corresponding merged value of the corresponding parameter. The error value calculation and merger steps are repeated so as to reduce the total number of schedule periods.
