Abstract: Characteristics of a reservoir may be used to generate multiple models of the reservoir with hydraulic fractures. Simulated configurations of the hydraulic fractures in the models may be used to select one or more of the models as representative model(s) for the reservoir. The representative model(s) may be used in development of the reservoir. Hydraulic fracturing may increase productivity at shale and tight rock reservoir by creating more effective flow paths to production.

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.
