Numberical simulation of fluid flow in porous fractured rock by Orla A. Dardis Download PDF EPUB FB2

The simulation of realistic multiphase flow problems in porous media requires efficient solution methods and means for handling the complicated structure of the media. The numerical toolbox UG has been developed to be able to use the approaches-multigrid, unstructured grids, adaptivity, and parallel computing-for a wide range of by: Abstract An original 3D numerical approach for fluid flow in fractured porous media is proposed.

The whole research domain is discretized by the Delaunay tetrahedron based on the concept of node saturation. Tetrahedral blocks are impermeable, and fluid only flows through the interconnected interfaces between by: 3.

The reality is that many processes operate together within subsurface systems, and this is particularly true for fluid flow and deformation of fractured rock masses.

The aim of this book is to begin to explore how advances in numerical modelling can be applied to understanding the complex phenomena observed in such systems. Although mainly based on original research, the book also includes the fundamental principles and practical methods of numerical modelling.

Random Walk Methods. File Size: 4MB. A Multiple Interacting Continua method (MINC) is presented which is applicable for numerical simulation of heat and multi-phase fluid flow in multidimensional, fractured porous media.

This method is a generalization of the double-porosity concept. The reality is that many processes operate together within subsurface systems, and this is particularly true for fluid flow and deformation of fractured rock masses. The aim of this book is to begin to explore how advances in numerical modelling can be applied to understanding the complex phenomena observed in such systems.

Scientific understanding of fluid flow in rock fractures--a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storage--has grown significantly in the past 20 years.5/5(1).

Lattice Boltzmann simulation of flow in simplified 2D or 3D porous media have been able to provide numerical evaluation of tortuosity [21] and permeability [22] for different values of the solid. Multiphase Fluid Flow in Porous and Fractured Reservoirs discusses the process of modeling fluid flow in petroleum and natural gas reservoirs, a practice that has become increasingly complex thanks to multiple fractures in horizontal drilling and the discovery of more unconventional reservoirs and resources.

The book updates the reservoir engineer of today with the latest developments in. In recent years, many methods including laboratory experiment, theoretical analysis and numerical simulation have been employed to investigate fluid flow in fractured porous media.

However, due to the complex and uncertain geometric properties of rock masses in deep underground, deep studies on the fluid flow in fractured porous media such as permeability prediction and/or nonlinear flow are.

Despite of many years of studies, predicting fluid flow, heat, and chemical transport in fractured-porous media remains a challenge for scientists and engineers worldwide. This monograph is the third in a series on the dynamics of fluids and transport in fractured rock published by the American Geophysical Union (Geophysical Monograph Series.

Abstract [1] We provide a numerical procedure for the simulation of two-phase immiscible and incompressible flow in two- and three-dimensional discrete-fractured media. The concept of cross-flow equilibrium is used to reduce the fracture dimension from n to (n-1) in the calculation of flow in the concept, which is often referred to as the discrete-fracture model, has a.

simulate multiphase fluid flow. In this review we focus on the methods that have been used to simulate multiphase fluid flow in porous, fractured, and fractured porous geo-meterials on the pore scale. FUNDAMENTALS [9] All of the properties of fluids and their behavior in the vicinity of solid surfaces can, in principle, be understood inCited by: The phenomena of fluid flow in fractured rock is dominated by the fact that is not all parts of the domain are in hydraulic communication.

In theory, it is possible to determine connectivity and permeability from stochastic parameters that describe the fracture by: The permeability theory of fractured rock mass has a wide range of engineering applications.

The surface roughness and structure tortuosity have a significant effect on the character of fluid flow through the fracture. Based on the standard fracture curves with different JRC values given by Barton (), a rough single fracture model is : Ge Zhang, Yuan Tian, YingJun Li.

The authors adopted a high-order numerical manifold method to improve the simulation accuracy of fluid flow in heterogeneous porous media. They developed a regular mathematical mesh, which is independent of the physical domain and is very efficient and by: 1.Therefore, new numerical simulation methods and deep explanations of fluid flow behaviors in fractured porous media are still needed.

This special issue aims at presenting recent advances in studies on the 3D fracture network reconstruction, fluid flow modeling and permeability estimation of rock fractures.This fact can be attributed to the complexity of the phenomena which include multicomponent fluids, multiphasic flow and rock-fluid interactions.

Since its formulation inDarcy’s law has been generalized to describe multi-phase compressible fluid flow through anisotropic and heterogeneous porous and fractured rocks.
