Experimental Validation and Calibration of the Galvin Model with Artificial Tight Sandstones with Controlled Fractures

open access: yesApplied Sciences, 2023
The study of fractures in the subsurface is very important in unconventional reservoirs since they are the main conduits for hydrocarbon flow. For this reason, a variety of equivalent medium theories have been proposed for the estimation of fracture and ...

A hybrid-mixed finite element method for single-phase Darcy flow in fractured porous media [PDF]

open access: yesAdvances in Water Resources, 2021
We present a hybrid-mixed finite element method for a novel hybrid-dimensional model of single-phase Darcy flow in a fractured porous media. In this model, the fracture is treated as an $(d-1)$-dimensional interface within the $d$-dimensional fractured ...

Lab and Field Scale Modeling of Near Miscible CO2 Injection in Different Porous Mediums [PDF]

open access: yesJournal of Petroleum Science and Technology, 2015
The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work,

1923–2023: One Century since Formulation of the Effective Stress Principle, the Consolidation Theory and Fluid–Porous-Solid Interaction Models

open access: yesGeotechnics, 2022
In 1923, Karl Terzaghi developed the theory of soil consolidation in which he introduced the concept of effective stress (ES). Over the past century, various theoretical aspects have been unraveled regarding the Effective Stress Principle (ESP) and the ...

Effective Elastic and Hydraulic Properties of Fractured Rock Masses with High Contrast of Permeability: Numerical Calculation by an Embedded Fracture Continuum Approach

open access: yesAdvances in Civil Engineering, 2019
In this work, the hydromechanical modeling of the fractured rock masses was conducted based on a new numerical simulation method named as embedded fracture continuum (EFC) approach. As the principal advantage, this approach allows to simplify the meshing

A double scale methodology to investigate flow in karst fractured media via numerical analysis. The Cassino plain case study (Central Apennine, Italy) [PDF]

open access: yes, 2018
A methodology to evaluate the hydraulic conductivity of the karstmedia at a regional scale has been proposed, combining pumping tests and the hydrostructural approach, evaluating the hydraulic conductivity of fractured rocks at the block scale ...

Determining the REV for Fracture Rock Mass Based on Seepage Theory

open access: yesGeofluids, 2017
Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its ...

Correspondence between one- and two-equation models for solute\ud transport in two-region heterogeneous porous media [PDF]

open access: yes, 2012
In this work, we study the transient behavior of upscaled models for solute transport in two-region porous media. We focus on the following three models: (1) a time non-local, two-equation model (2eq-nlt).

Self‐consistency of a heterogeneous continuum porous medium representation of a fractured medium [PDF]

open access: yesWater Resources Research, 2000
A possible approach to representing fractured rocks is to use heterogeneous continuum porous medium (CPM) models in which each grid block has an effective permeability appropriate to represent the network of fractures within the block. It needs to be demonstrated that the approach is self‐consistent; that is, the effective permeability on a length ...
