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

In this paper, we use the PDE interface of COMSOL Multiphysics® software to implement the 2.5D frequency wave-number domain method to investigate the wave propagation in a deviated borehole penetrating a transversely isotropic formation. A convolutional perfectly matched layer is ... En savoir plus

This work encompasses different physics involved in fluid flow in shale gas reservoir. Non-linear equations for fluid flow are solved with COMSOL Multiphysics® PDE module. It focuses on comparing the performance of various species transport flux models by accounting for inter-molecular ... En savoir plus

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... En savoir plus

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer ... En savoir plus

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... En savoir plus

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... En savoir plus

In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing ... En savoir plus

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 ...

Direct numerical simulation of single- and two-phase flow in real pore systems is addressed in our paper. The X–ray computed micro-tomography technique has been applied first to reconstruct in details a real pore space of a subcentimetric sample. Making use of dedicated software (ScanIP) ...
