Deliverable 5.1 Guideline for uncertainty quantification of rock mechanical properties

Abstract

This report introduces some practical methods that can be used to quantify the uncertainties involved in geomechanical properties estimation. Among the various aspects of uncertainties, this report mainly focuses on uncertainties involved in regression when deriving mechanical properties from empirical correlations and spatially-averaged properties. In addition, it also briefly introduces other types of uncertainties that can be involved in entire process of geomechanical properties estimation with conceptual methods. In overrall context of a risk assessment, the information described in this report can be used to prepare statistical inputs for the hazard assessment phase of CO2 containment risk assessment.
