Well Logging
Well logging is the recording of information about subsurface geologic formations, including records kept by the driller and records of mud and cutting analyses, core analysis, drill stem tests, and electric, acoustic, and radioactivity procedures.
The purpose of well logging is to identify formation and other downhole properties of the well bore.
Well logging tools can include radioactive, electric, mechanical, and sonic tools, among others.
