Short summary
Rock fracture connectivity is key for oil/gas, geothermal energy, and nuclear waste storage. This study predicts the zero-percolation threshold – when fractures connect – using simulations. A model links this threshold to fracture number, length, and orientation, enabling fast predictions. Tests on simulated and real fractures confirm its accuracy across sizes/orientations. Provides key tool for subsurface engineering.
