The proposed study concerns propagation of fluid-driven or hydraulic fractures in reservoir rock. These fractures, created by pumping a viscous fluid from a wellbore, are widely used to increase production from gas and oil bearing rock, and considered a viable mechanism to reduce greenhouse gases in the atmosphere by injecting them into underground formations. Pre-existing fractures (bedding planes, joints, faults, and pre-existing fracture networks) ubiquitous in reservoir rock often play defining role in hydraulic fracture propagation. This research will improve understanding of this role, and provide novel theoretical, computational, and experimental tools for hydraulic fracture modeling.

所提出的研究涉及储层岩石中流体驱动或水力裂缝的扩展。通过从井筒泵送粘性流体而产生的这些裂缝被广泛用于增加含气和含油岩石的产量，并且被认为是通过将温室气体注入地下地层来减少大气中温室气体的可行机制。储层岩石中普遍存在的预先存在的裂缝（层面、节理、断层和预先存在的裂缝网络）通常在水力裂缝扩展中起决定性作用。这项研究将提高对这一作用的理解，并为水力压裂建模提供新的理论，计算和实验工具。
