A Coupled Reservoir-Geomechanics Model and Applications to Sand Production Simulation
Sand production is a serious problem in petroleum industry, its becomes more critical as operators follow more aggressive production strategies. In this paper, focusing on the coupling between fluid flow and solid deformation/collapse, a consistent geometrical model for sand production prediction is established. Finite element method with explicit and sequential iterative algorithm is used to solve the coupled governing equation system. Simulation results of perforation cavity stability and sand production rate are presented. The calculation indicates that the critical pressure drawdown and the pressure gradient variable take as the important roles in sand production process. The study suggests that the proposed model may be used to generate quantitative information for predicting sand production and optimizing pressure drawdown.
