In contrast to the conventional approach of sanding prediction where only one particular method is selected (e.g., either empirical, analytical, numerical, or experimental), a comprehensive geomechanical approach is presented in this paper to predict excessive sand production, which includes:
employing an analytical method with the combination of experience based empirical rules and analytical expressions to assess the sand production risk under simplified conditions,
performing a numerical study using the desired constitutive relationships in a three-dimensional field environment to examine wellbore and perforation device stability under the complex configurations and to validate the initial calculations, and
conducting an experimental approach using laboratory-rock mechanical testing techniques to calibrate the sanding prediction under simulated downhole conditions. The presented approach uses the self-calibrated predictions on sand production via multiple methods, which can lead to a sensible decision for selecting effective and economical sand-control measures. The unified approach was illustrated in a case study where the critical drawdown pressure was sensibly determined by multiple methods.
