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 ...

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 a kind. COMSOL has been used recently for modeling the thermal multiphase flow through porous media in the ...

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 ...

Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, using a model of homogeneous resistivity on which a DEM (Digital Elevation Model) profile of the Deep Freeze ...

Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same borehole, but in greater depth. We use COMSOL Multiphysics® for the development of a 2D model that simulates ...

Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate for a deep drilling project aimed to understand the volcanic structure. The CFDDP project, aims to ...

A design method for BHE fields in the absence of groundwater flow is presented, based on the superposition of effects. The effects of any periodic heat load with a period of one year can be obtained by a weighted sum of the effects of a monthly unit step heat load, properly displaced in time. The interference among BHEs is evaluated by the superposition of effects in space. The result of the ...

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 ...

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of storage is based on a clay formation with low permeability, homogeneity and continuity (i.e Callovo-Oxfordian ...
