Basic well Logging Analysis – The Resistivity Logs. Hsieh, Bieng-Zih Fall 2009. General. Resistivity logs are electric logs which are used to: (1) determine hydrocarbon versus water-bearing zones, (2) indicate permeable zones, and (3) determine resistivity porosity.
Determining when use of an induction log is preferred over an electrode log such as the Laterolog*.
