A Model for coupled geomechanics and multiphase flow in fractured porous media using embedded meshes

Advances and challenges in shale oil development: A critical review

“…It is worth noting that the fracture network generated by hydraulic fracturing in shale has a great impact on production performance (Meng et al, 2020). Ren et al (2016Ren et al ( , 2018 proposed a mixed discretization approach to fully couple geomechanics and multiphase flow, which can tackle with complex fractures and predict the performance, but the flow part is not a compositional model. Therefore, it is necessary to develop a shale oil reservoir numerical simulation method integrating both the compositional model and complex fracture networks.…”

Simulation of coupled multiphase flow and geomechanics in porous media with embedded discrete fractures

“…In summary, in the EFEM methods, the global momentum balance equation (18) remains the same, but the discrete traction balance residual equations at time are replaced as:…”

“…[14][15][16][17] Recently, these methods have also been combined for simulation of coupled multiphase flow and mechanics in fractured porous media using a mixed FE/FV discretization. 18 In this work, we propose an FV discretization of the multiphase mass balance equations along with an FE scheme for the momentum balance equation. The contribution of the fractures to the flow and transport is captured by employing the embedded discrete fracture model (EDFM) 7,8 that is an extension of a traditional two-point flux FV scheme to discontinuous media.…”

Parallel embedded discrete fracture method for flows in fractured porous media

“…Также преимуществом является то, что данный подход может быть расширен на многофазные и многокомпонентные течения. В частности, EDFM успешно применяется для анализа многофазных течений и задач повышения нефтеотдачи [Moinfar et al, 2014;Xu et al, 2019b], моделирования гидроразрыва пласта и задач геомеханики [Norbeck et al, 2016;Ren et al, 2018;Xu et al, 2019a].…”
