Petroleum (related) geomechanics applies the principles of engineering mechanics to predict the failure of porous, discontinuous, granular, heterogeneous, and anisotropic materials, whose properties vary with the type and the degree of loading. It is “the mechanics for difficult materials”. In this presentation we outline the importance of Petroleum Geomechanics, the difficulties, and the ...

A Normal Mode Analysis of the Chesapeake Bay has reached the phase of performing a time-series analysis. Prior attempts using generalized eigenfunctions obtained from COMSOL have led to extraction of power spectra using a partial domain extraction and a waveletlike correction to the result.A new approach has been developed which effectively solves the spatial equivalent of the Initial Value ...

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 ...

In volcanic areas, the presence of heterogeneous materials and high temperatures affect the rheological behaviour of the Earth's crust that calls for considering the anelastic properties of the medium surrounding the magmatic sources. A thermo-mechanical numerical model is performed for evaluating the temperature dependency of the elasto-plastic solution. Both temperature distributions and ground ...

The efficiency of bioreactor lanfills depends on a homogeneous distribution of leachate in the waste body. Therefore, optimisation of leachate injection systems is a challenging issue for operators. Most studies have shown that surface Electrical Resistivity Tomography (ERT) can be a suitable method to study moisture distribution (2D and 3D). But resistivity inversion models used to date are ...

Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce significant new challenges. Starting from digital imaging data, the paper introduces an image-to-simulation ...
Multiphysics Between Deep Geothermal Water Cycle, Surface Heat Exchanger Cycle and Geothermal Power Plant Cycle
International Centre for Geothermal Research, Helmholtz Centre Potsdam, GFZ German Research Centre For Geosciences, Telegrafenberg, Potsdam, Germany
Within the framework of Groß Schönebeck project in the North German Basin of Germany, multiphysics between deep geothermal reservoir, boreholes, heat exchangers and power plant is crucial to study lifecycle behavior of each component thereafter a later coupling to study lifecycle and recovery of the overall geothermal system. Study is divided into geothermal water cycle, surface heat exchanger ...

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 ...

Seawater intrusion is a significant practical problem for coastal regions, which requires human efforts directed to prevent the degradation of freshwater aquifers. In the present paper we examined the homogeneous confined aquifer in terms of a 2D model which represents a vertical cross-section perpendicular to the sea coast. Several numerical simulations were performed in order to determine the ...

A Normal Mode Analysis (NMA) of the Chesapeake Bay was performed using Dirichlet boundary conditions and FEMLAB. The lowest 100 eigenstates were calculated and compared to a finite difference solution. Based on the normal modes derived numerically, surface current vector fields can be calculated. The vector fields of the Chesapeake Bay provide tools for the solution of problems such as the ...
