Disclosed is a method of monitoring the behaviour of a subsurface volume. The method comprises transforming a single discrete parameter or an ensemble of discrete parameters describing an attribute of the subsurface volume into N indicator parameters each having 2 possible discrete values. Each discrete parameter has N possible discrete values with N greater than or equal to 2. The method also comprises, for each of the two value classes of each indicator parameter, determining the anisotropic distance to a value transition interface. Each of the indicator parameters are then transformed into a corresponding continuous parameter using the determined anisotropic distance to the value transition interface and the continuous parameters are used in a history matching process. |
