This project aims to improve understanding of subsurface fluid transport through fractures. Fractures in rock provide interconnected, hydraulically conductive networks enabling large-volume fluid transport through sedimentary basins. The ability of a fracture to transmit fluid is primarily controlled by the in situ stress field, but also by rock strength, fracture plane orientation and roughness and pore-fluid pressure. We have a good understanding of in situ stress within many sedimentary basins, but know very little about the nature and origin of natural fractures. This project aims to provide a detailed, quantitative understanding of the nature and origin of natural fractures in the subsurface, which is critical for predicting fluid migration within aquifers, carbon dioxide storage sites, and geothermal and hydrocarbon reservoirs.

该项目旨在提高对地下流体通过裂缝输送的理解。岩石中的裂缝提供了相互连接的水力传导网络，使大量流体能够通过沉积盆地输送。裂缝的渗流能力主要受地应力场的控制，但也受岩石强度、裂缝面方向和粗糙度以及孔隙流体压力的控制。我们对许多沉积盆地内的原地应力有很好的了解，但对天然断裂的性质和起源知之甚少。该项目旨在提供对地下天然裂缝的性质和起源的详细定量了解，这对于预测含水层，二氧化碳储存地点以及地热和碳氢化合物储层内的流体迁移至关重要。
