Robust numerical implementation of a 3D rate-dependent model for reservoir geomechanical simulations

A 3D elasto-plastic rate-dependent model for rock mechanics is formulated and implemented into a Finite Element (FE) numerical code. The model is based on the approach proposed by Vermeer and Neher (A soft soil model that accounts for creep. In: Proceedings of the International Symposium “Beyond 2000 in Computational Geotechnics,” pages 249-261, 1999). An original strain-driven algorithm with an Inexact Newton iterative scheme is used to compute the state variables for a given strain increment.The model is validated against laboratory measurements, checked on a simplified test case, and used to simulate land subsidence due to groundwater and hydrocarbon production. The numerical results prove computationally effective and robust, thus allowing for the use of the model on real complex geological settings. 相似文献

In this paper the Quasi-Particle (QP) technique has been applied for the first time to the study of beam propagation in slowly varying sound-speed profiles with an upper boundary, typical of some underwater acoustic environments. With the aim of testing the possibilities and the limitations of this new technique, particular attention has been devoted to special effects. The results of this analysis have been used to give some criteria for a proper modeling of the ocean environment from the Quasi-Particle point of view. 相似文献
