Oil emulsions in naturally fractured Porous Media
Petroleum, 2019 Most of the studies regarding the formation and stability of emulsions focus on the conditioning and management of crude oil on surface facilities. Since a great deal of the crude oil produced is in the form of stable emulsions, it is often claimed that ...

Dual Virtual Element Methods for Discrete Fracture Matrix models
Oil & Gas Science and Technology, 2019 The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name few applications.

A Coupled Darcy-Forchheimer Flow Model in Fractured Porous Media
Applied Sciences, 2022 Aiming at nonlinear flow in fractured porous media, based on the finite volume method, the discrete equations of Darcy flow in porous and Forchheimer flow in fracture were derived, and a solution method for coupling flow is proposed. The flow solution by

Fracture Model Reduction and Optimization for Forchheimer Flows in Reservoir
, 2017 In this study, we analyze the flow filtration process of slightly compressible fluids in fractured porous media. We model the coupled fractured porous media system, where the linear Darcy flow is considered in porous media and the nonlinear Forchheimer ...

A multiscale flux basis for mortar mixed discretizations of reduced Darcy-Forchheimer fracture models [PDF]
, 2018 In this paper, a multiscale flux basis algorithm is developed to efficiently solve a flow problem in fractured porous media. Here, we take into account a mixed-dimensional setting of the discrete fracture matrix model, where the fracture network is ...

Unstable Density-Driven Flow in Fractured Porous Media: The Fractured Elder Problem
Fluids, 2019 The Elder problem is one of the well-known examples of an unstable density-driven flow (DDF) and solute transport in porous media. The goal of this research is to investigate the influence of fracture networks on this benchmark problem due to the great ...
