IS - Phase Field Modeling of Coupled Problems 3D phase-field for pressurized fracture propagation in heterogeneous media

چکیده
This work presents recent progress in phase-field-based fracture modeling in heterogeneous porous media. Existing algorithms that have been developed in the last years are extended to tackle three-dimensional configurations. Our solution technique is formulated in terms of a nested Newton loop that combines a primal-dual active set method (required for treating the crack irreversibility) and a Newton method to solve the nonlinear, fully-coupled PDE system. An advanced numerical test demonstrates the capabilities of our method.

A Phase-Field Method for Propagating Fluid-Filled Fractures Coupled to a Surrounding Porous Medium
The recently introduced phase-field approach for pressurized fractures in a porous medium offers various attractive computational features for numerical simulations of cracks such as joining, branching, and non-planar propagation in possibly heterogeneous media. In this study, the pressurized phase-field framework is extended to fluid-filled fractures in which the pressure is computed from a ge...
متن کاملA primal-dual active set method and predictor-corrector mesh adaptivity for computing fracture propagation using a phase-field approach
In this paper, we consider phase-field-based fracture propagation in elastic media. The main purpose is the development of a robust and efficient numerical scheme. To enforce crack irreversibility as a constraint, we use a primal-dual active set strategy, which can be identified as a semi-smooth Newton’s method. The active set iteration is merged with the Newton iteration for solving the fully-...
متن کاملPhase-field Modeling of Pressurized Fractures in a Poroelastic Medium
In this paper we present an incremental formulation of the phase field model for a fluid filled crack in a poroelastic medium. The mathematical model represents a linear elasticity system with fading elastic moduli as the crack grows that is coupled with an elliptic variational inequality for the phase field variable. The convex constraint of the variational inequality assures the irreversibili...
متن کاملA Novel Combinatorial Approach to Discrete Fracture Network Modeling in Heterogeneous Media
Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness of data have incapacitated conventional deterministic methods in fracture network modelin...
متن کامل4D geomechanical simulations for field development planning
3D and 4D geomechanical can be time-consuming to build and calibrate. However, once such a model is built, it is relative straightforward to use this model for various field development and management applications. In so doing, the return on the initial investment of time and effort in the creation of a 4D geomechanical model can be substantial. I present a case study where a 4D geomechanical m...
