n: heavy-duty paper perforated with several very small holes (pores). Folded in accordion pleats, micropore paper often serves as a secondary filter element in an engines fuel system. Fuel passes through the pores, while the unperforated part of the paper stops dirt. microresistivity log n: a resistivity logging tool consisting of a spring device and a pad. While the spring device holds the pad firmly against the borehole sidewall, electrodes in the pad measure resistivities in mud cake and nearby formation rock. See resistivity well logging.

n: a record of the resistivity of a formation. Usually obtained when an electric log is run. See resistivity well logging.

one of various logs that measure some component of resistivity.

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
