The hydromechanical characterization of a fractured and fluid-saturated subsurface domain has a number of important applications, such as the sustainable use of groundwater, the optimized production of geothermal energy and hydrocarbons, and the safe geological storage of CO2 and nuclear waste. Assessing the hydromechanical properties (permeability and storage capacity) of a fractured rock indirectly, for example, by using seismic data, has been speculated but not yet proven feasible. The most promising speculation is based on recent studies showing that the attenuation of seismic waves is sensitive to the degree of hydraulic interconnectivity of fractures in idealized fracture models. Further research however is necessary to quantify this sensitivity for realistic fracture networks. This is the target of our proposed interdisciplinary research project.

裂隙和流体饱和地下区域的流体力学特性具有许多重要的应用，例如地下水的可持续利用，地热能和碳氢化合物的优化生产，以及CO2和核废料的安全地质储存。间接评估破裂岩石的流体力学性质（渗透性和储存能力），例如，通过使用地震数据，已经被推测，但尚未被证明是可行的。最有希望的推测是基于最近的研究，表明地震波的衰减对理想化裂缝模型中裂缝的水力连通程度很敏感。然而，进一步的研究是必要的，以量化这种敏感性的现实裂缝网络。这是我们提出的跨学科研究项目的目标。
