n: the recording of the resistance of formation water to natural or induced electrical current. The mineral content of subsurface water allows it to conduct electricity. Rock, oil, and gas are poor conductors. Resistivity measurements can be correlated to formation lithology, poros- ity, permeability, and saturation and are very useful in formation evaluation. See electric well log.

n: a kind of logging method in which the resistivity of rock is measured, usually used to evaluate the formation oiliness
