Porosity vs. permeability graphs are used to evaluate the quality of reservoir rocks by examining how easily fluids can flow through them. These plots help identify trends between storage capacity (porosity) and flow potential (permeability), which are critical for applications like groundwater modeling, hydrocarbon exploration, and CO₂ sequestration. They also assist in comparing different formations or lithologies to guide drilling and production decisions.
