In-situ stress orientation refers to the direction of the principal stresses present within the Earth's crust, which significantly influences geological phenomena such as faulting, fracturing, and the stability of underground structures. Understanding this orientation is crucial for activities like drilling, mining, and earthquake risk assessment, as it helps predict how rocks will respond to natural and human-induced forces.
Fracture networks are interconnected systems of cracks or fractures in geological formations that significantly influence fluid flow and mechanical properties of rocks. Understanding these networks is crucial for applications such as hydrocarbon extraction, groundwater management, and geothermal energy exploitation.
