The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the nanometer scale. Using a multiscale imaging protocol, a Devonian shale rock sample with heterogeneities is ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
Modelling the Thermal Impact of a Repository for High-Level Radioactive Waste in a Clay Host Formation
Belgian Nuclear Research Centre (SCK-CEN), Waste & Disposal Department, Mol, Belgium
Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the physical impacts of the heating on the geological media around a deep disposal system. The software was found ...

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 ...

Partial melting occurs beneath mid-ocean ridges in Earth's mantle and the resulting liquid migrates to the surface to form a new oceanic crust. In this system, mass can be exchanged between the liquid and solid phases through melting and solidification and, at the high temperatures and pressures associated with the Earth's interior, the solid matrix deforms through the process of compaction, ...

In a soil pore, water flows through the biofilm, where the density of the latter was assumed to represent a flow resistance. This mechanism was implemented as a local change of fluid viscosity proportional to local biofilm density. It was assumed that diffusive substrate transport is possible through the biofilm region such that the biofilm was able to degrade the substance. Maximum flow ...

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic flexure of the lithosphere beneath the edifice load, and (2) Pressurization of a magma-filled chamber that serves ...

In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and investigate the temperature gradient developed in the cap rock. Ultimately, results from this study will lead to an ...

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 ...
