Abstract: A multivariate modeling tool utilizes reversible transformations to transform subsurface properties of wells into a modeling space in which the subsurface properties are decorrelated and unconstrained. The subsurface properties of a region are independently propagated from the well(s) in the modeling space. Reverse transformations are applied to the subsurface properties in the modeling space to generate a subsurface representation for the region. The subsurface representation honors constraints on the subsurface properties and correlations between the subsurface properties.
