    Study Notes

    SP Logging

    • The total SP potential measured in the borehole is comprised of several components.

    Components of SP Potential

    • One component of the total SP potential exists due to the flow of an electrolyte through a nonconductive medium.

    SP Log Measurements

    • The SP log measures the spontaneous potential difference between the borehole and a remote reference electrode.

    SP Log Corrections

    • Learning outcome: Applying corrections needed for SP logs before using them for interpretation.

    Age of SP Log

    • The SP log is considered a mature logging technique, meaning it is an older method.
