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 ...

A novel numerical method characterizing groundwater flow in unconfined aquifer is demonstrated. In contrast to the conventional method (Dupuit approach considering horizontal flow only), hydraulic head is simulated in horizontal and vertical directions. The new approach is introduced via developing a 2-D-axisymmetric model representing the vertical cross section of the aquifer. The model solves ...

Geomagnetic Modeling with COMSOL Multiphysics® Software - new

[1]Chungnam National University, Daejeon, Korea

Here we aim to advance geomagnetic modeling approaches using COMSOL Multiphysics® software and improve the degree of detail that can be obtained from the measured magnetic field. First, we carried out benchmark tests by comparing the computed results using the widely used analytic solutions for rectangular bodies with arbitrary direction of magnetization with those from the AC/DC Module of ...

Pore-Level Influence of Contact Angle on Fluid Displacements in Porous Media - new

H. Ali Akhlaghi Amiri[1]
[1]University of Stavanger, Stavanger, Norway

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability effects demands pore-level investigations which are still limited. In this paper, COMSOL Multiphysics® software ...

Modeling of Usage of Air Injection Well in a Geothermal System

X. Ma[1] and J. Grabe[1]

[1]Institude for Geotechnics and Construction Management, Hamburg University of Technology, Hamburg, Germany

Natural groundwater flow can increase the efficiency of geothermal system. But groundwater flow is not available everywhere. A patented new idea is to use air injection well to create artificial flow in sandy or gritty soils. The governing equations of fluid flow and heat transfer problem were solved with the COMSOL’s Earth Science Module.

Short-Term Behavior and Steady-State Value of BHE Thermal Resistance - new

S. Lazzari[1], A. Priarone[2],
[1]DIN, University of Bologna, Bologna, Italy
[2]DIME-TEC, University of Genova, Genova, Italy

The transient behavior of the thermal resistance of single and double U-tube borehole heat exchangers (BHEs) is investigated numerically by means of COMSOL Multiphysics® software with reference to the 2D cross section of usually employed BHEs. The study is performed in a dimensionless parametrical form, the parameters being the ratio between the thermal conductivities of grout and ground, the ...

Modeling with COMSOL the Interaction Between Subducting Plates and Mantle Flow

[3]Istituto Geologia Ambientale e Geoingegneria – CNR, Roma, Italy

Subduction processes have great importance as are related to volcanism and earthquake occurrence. Old and cold plates should subduct steeper than younger ones, but the subduction angle is highly variable and does not always correlate with the age of the plates. Some researchers propose a global or net westward drift of the lithosphere relative to the mantle and this assessment is still a matter ...

Deep-Seated Spreading Model Tested on Etna Mount with FEM

[1]Istituto Nazionale di Geofisica e Vulcanologia sezione di Catania
[2]Università di Catania

Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward.  According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del ...

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

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 ...
