The authors present a closer look on the Single-Well Injection-Withdrawal Experiment (SWIW) or Push-Pull Experiments and its ability to determine the groundwater velocity, as one of the major parameters concerning reservoir management and underground reservoir characterization. The flow field is modeled using analytic and numerical solutions. Different modes like Darcy-law, solute-transport and ...

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 ...

Safe short term storage of CO2 depends mainly on structural and solubility trapping. On longer term, mineral trapping is also contributing to the trapping of CO2. To be able to investigate the importance of these different storage mechanisms, a finite element model for simulation of CO2 injection has been developed in COMSOL Multiphysics®. The model describes and solves for two-phase 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 ...

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 ...

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground cavities. In order to accurately perform these multiphysics modelings at high space and time scales, it is ...

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 ...

Green house gases emission associated with natural hazard of underground coal seam fire has been recognized as a worldwide problem leading to global warming threat. Therefore, in this paper a model to study underground coal fire is presented and the results will be devoted to strategic development of coal fire extinction technology within the framework of Sino-German Coal Fire Research ...

The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by pure H2O. We considered a 1-D geometry and we developed a dynamic model that presents a clear interface ...

The percolation of water into soil can be modeled considering Darcy's Law in laminar flow. In this manner the key property is the coefficient of hydraulic conductivity. Its determination can be made through laboratory or field testing. One of the most known field tests used for determination of this property is the Slug Test. This test consists of a perforated well in the ground where a known ...
