Archie's Law

Archie's Law describes how the electrical conductivity of a porous material containing water relates to its water saturation and its overall properties. Specifically, it states that the electrical current passing through such a material depends on how much water is present, the material’s inherent properties, and the structure of the pores. In simple terms, as more water fills the pores, the material becomes more conductive, allowing electricity to pass more easily. This relationship helps in fields like oil and groundwater exploration, where measuring electrical conductivity can indicate how much fluid is present within rocks or soils.
