| A well log is a record of one or more physical measurements as a function of depth in a borehole (From “Encyclopedic Dictionary of Applied Geophysics”). To measure the various values at once, one or more sondes comprise a tool string. Formation evaluation, lithological classification, and other geological interpretations are carried out from the logging curves or crossplots. |
