We present a software tool for simulations of subsurface flow and solute transport in combination with comprehensive intra-phase and inter-phase geochemistry. The software uses PHREEQC as a reaction engine to COMSOL Multiphysics®. The coupling with PHREEQC gives major advantages over COMSOL’s built-in reaction capabilities, i.e., the soil solution is speciated from its element composition ...

For the numerical solving of the equations, Comsol has been applied. Simulations have been modeled in 2D Cartesian, in cylindrical coordinate system and in a “mantle-like” cylindrical-shell. Mantle dynamics is controlled by the Rayleigh number (Ra), which is the ratio of the buoyancy and viscous force. The effect of Ra has been studied in the range of 1e4 to 1e7. The significance of the ...

Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time frames involved. Performing a safety analysis of a radioactive waste disposal system requires therefore ...

Mathematical modeling tools are extensively used in Geosciences to delineate the earth structure at various spatial scales as well as to simulate coupled earth processes involving multiphysics concepts. COMSOL, a Multiphysics finite element method based numerical modeling package, can be used to analyze complex systems like earth where various physical parameters are involved and ...

The Amplitude vs. Offset (AVO) technique infers the elastic properties of geological targets from pre-stack seismic data. AVO analysis significantly reduces the drilling risks for oil and gas exploration and development, particularly in the Gulf of Mexico. One strand of the current, EC-funded ADEMA Project is to evaluate AVO in coal-bearing strata. The target application areas are long-wall ...

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which 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 ...

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 ...

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 ...
