摘要：Geological formation resistivity is determined. Circuitry is located within theborehole casing that is adjacent to the geological formation. The circuitry can measure
one or more voltages across two or more voltage measurement electrodes associatedwith the borehole casing. The measured voltages are used by a processor to determinethe resistivity of the geological formation. A common mode signal can also be reducedusing the circuitry.
