1. A generic term including all electrical borehole logs (SP, normal, lateral, laterologs, induction, microresistivity logs, electrical image log, through-casing resistivity log). Two basic electrode configurations are shown in Figure E-10. 2. Records of surface resistivity surveying; compare electric survey. 3. Electrolog, a borehole log that usually consists of SP and two or more resistivity logs, such as short and long normal and long lateral logs. Electrolog is a Dresser Atlas tradename.
