Solution of Poroelastic Equations with Different Base Variables Using Equation-based Modeling

M. H. Akanda [1], Y. Cao [1], A. J. Meir [1],
[1] Department of Mathematics & Statistics, Auburn University, Auburn, AL, USA

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in reservoir engineering, bio-engineering, environmental engineering etc. We have used quasi-static poroelastic ...

Modeling CO2 storage Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå, F. Cuisiat, E. Aker, and E. Skurtveit
Norwegian Geotechnical Institute(NGI), Oslo, Norway

The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes occurring during injection. The model is based on the simultaneous resolution of the governing equations for two ...

The Effect of the Disintegration of Chemical Stratification on the Time-dependent Behavior of the Earth’s Mantle

A. Galsa, and M. Herein
Eötvös University
Budapest, Hungary

Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing and homogenization of the dense D’’ on the time-dependent behavior of mantle convection. A ...

Matching 4D Porous Media Fluid Flow GeoPET Data With COMSOL Multiphysics Simulation Results

Research Site Leipzig
Reactive Transport Division
Leipzig, Germany

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

Numerical Model for Leaching and Transporting Behavior of Radiocesium in MSW Landfill

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for containment of hazardous waste such as radiocesium-contaminated MSW generated by Fukushima Daiichi nuclear ...

Modeling Self-Potential Effects during Reservoir Stimulation in Enhanced Geothermal System - new

[2]INGV-Osservatorio Vesuviano, Naples, Italy

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from strict site-related conditions, mainly related to the reservoir rock’s permeability. In this work, SP ...

Scraping Non-Newtonian Power-Law Paint

C. R. Meyer [1], J. R. Rice [1],
[1] Harvard University, Cambridge, MA, USA

A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. Simulations created in COMSOL Multiphysics® software are also presented to corroborate the shooting method and display ...

A 3D Multiphase Flow Model of Hydrogen Storage in Geological Formations

E. Abarca [1], A. Sainz-Garcia [1], F. Grandia [1],
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Renewable energies generate temporary mismatches between energy demand and supply. The conversion of surplus energy to hydrogen and its storage in geological formations is one option to balance this energy gap. Storage in deep saline aquifers is the most cost-effective option for underground hydrogen storage (Lord et al., 2014). A 3D multiphase flow model in a dome shaped geological formation ...

Assessment of Spatial Variably Saturated Flow by Irrigation Moisture Sensors in 2-Dimensions using the COMSOL Multiphysics 4.1

A. Boluwade, and C. A. Madramootoo
Bioresources Engineering, McGill University
Ste. Anne De Bellevue, QC

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which automates the van Genuchten equation. A hypothetical soil column 4m by 4m was set up with seven irrigation ...
