Effective porosity

Effective porosity refers to the portion of a material, such as rock or soil, that can store and transmit fluids, like water or oil. It considers only the interconnected spaces that allow liquids to flow, excluding isolated pores that do not contribute to fluid movement. This concept is crucial in fields like hydrology and petroleum engineering, as it helps determine how much water or oil can be accessed from underground sources. In essence, effective porosity provides insight into how easily fluids can move through a material, influencing resource management and environmental studies.
