Electromagnetic Field Computations for Saturated Porous Media

S. Cambon[1], I. Bogdanov[1]
[1]CHLOE, Bâtiment UFR Sciences et Techniques, Pau Cedex, France

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such ... En savoir plus

Evaluation of Instability of a Low-salinity Density-dependent Flow in a Porous Medium

Y. T. Habtemichael[1], R. T. Kiflemariam[2], H. R. Fuentes[1]
[1]Department of Civil & Environmental Engineering, Florida International University, Miami, FL, USA
[2]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

Seawater intrusion into coastal aquifers is usually modeled by using transport models that include account for the effect of variable-density on flow. Variable-density models can be validated with the Henry and Elder benchmark problems. However, when mixed convective flow is simulated ... En savoir plus

Simulation of Brine Reflux and Geothermal Circulation in Large Carbonate Platforms: An Attempt to Predict Dolomite Geo-Bodies

M. Pal, and C. Taberner
Shell International Exploration and Production B.V.
Rijswijk, The Netherlands

Significant volumes of the worlds proved reserves are in dolostone reservoirs. Scope for recovery and success/upside of new exploration plays depend on the chances of encountering dolostone reservoirs with good reservoir properties. Although dolostones make excellent reservoirs in ... En savoir plus

3D Modeling of Fracture Flow in Core Samples Using ?-CT Data

S. Hoyer[1], U. Exner[2], M. Voorn[1], A. Rath[3]
[1]Department of Geodynamics and Sedimentology, University of Vienna, Austria
[2]Museum of Natural History, Vienna, Austria
[3]OMV ESG-D Production Geology, Vienna, Austria

Knowledge on flow behavior in fractured reservoir rocks is of great interest in petroleum engineering as well as for geothermal assets. Due to the big difference of magnitude (fracture aperture: ~?m, lateral extension of reservoirs ~km), modeling of discrete fracture flow is not ... En savoir plus

Elasto-Plastic FEM Models Explain the Emplacement of Shallow Magma Intrusions in Volcanic Complexes

A. Bistacchi[1]
[1]Università degli Studi di Milano Bicocca, Milano, Italy

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone ... En savoir plus

Modeling of Bentonite Hydration Process in a High Level Waste Repository

M. Hokr[1], I. Skarydova[1]
[1]Technical University of Liberec, Liberec, Czech Republic

We deal with a problem of bentonite behavior during the saturation process in a high level waste repository of KBS-3V conception, SKB (2010). Bentonite is a type of clay with specific nonlinear behavior caused by water adsorption and swelling ability in contact with water. We solve ... En savoir plus

Expanding Your Materials Horizons

R.W. Pryor
Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number ...

A Coulomb Stress Model to Simulate Induced Seismicity Due to Fluid Injection and Withdrawal in Deep Boreholes

G. Perillo[1], G. De Natale[2], C. Troise[2], A. Troiano[2], M.G. Di Giuseppe[2], A. Tramelli[2]
[1]University of Naples Parthenope, Naples, Italy
[2]INGV, Osservatorio Vesuviano, Naples, Italy

Fluid injection and withdrawal in deep wells is a basic procedure in mining activities and deep resources exploitation, i.e. oil and gas extraction, geothermal exploitation, geothermal permeability enhancement and waste ?uid disposal. All these activities have the potential to induce ... En savoir plus

Simulation of Incompressible Flow through Rhombohedric Pores

R. Viola[1][3], F. Zama[2], M.Tuller[3], and E. Mesini[1]

[1]DICMA, University of Bologna, Bologna, Italy
[2]Dep. of Mathematics, University of Bologna, Bologna, Italy
[3]Dep. of Soil, Water, and Environmental Science, University of Arizona, Arizona, USA

Advances in visualization and discretization of pore structures by means of Computed Tomography, and rapidly increasing computational capabilities, allow numerical modeling of pore-scale fluid flow based on the incompressible Navier-Stokes equations rather than using a macroscopic ...

Numerical Inversion of Surface Deformation at Long Valley Caldera (California) By Using 3D Mechanical Models

S. Pepe, P. Tizzani, and A. Manconi
IREA-CNR, Napoli, Italy

We use 3D numerical models to analyze the ground deformation observed at Long Valley Caldera (LVC) between 1992 and 2000 via space-based geodetic techniques. More specifically, we implement a complex model that includes the topography and the material heterogeneities information of LVC. ... En savoir plus
