Are Uncertainties on the Spatial Distribution of Rock Properties Influential in Coupled Reservoir/Geomechanical Modeling?
A geostatistical approach is proposed to image the uncertainties attached to the rock moduli in a 3D geomechanical model. Then, this approach is applied to quantify the effects of these uncertainties on the calculated displacements and stresses in a geological structure undergoing depressurisation due to hydrocarbon production. It is shown that the resulting impact is far from negligible; in particular the stress field is impacted by the uncertainties related to the lithology spatial distribution. Consequently, these uncertainties should be accounted for in any mechanical risk analysis. The proposed geostatistical approach used to represent the spatial uncertainties on the rock properties is a powerful tool to develop sensibility analyses.
