Spectral gamma ray tools provide
insight into the mineral composition
of formations. The total gamma ray
spectra measured is resolved into the
three most common components of
naturally occurring radiation in sands
and shales—potassium, thorium, and
uranium (K, Th, and U, respectively).
These data are used to distinguish
important features of the clay or sand
around the wellbore. The clay type
can be determined, and sand can be
identified as radioactive. The deposition
of radioactive salts behind the
casing by the movement of water can
also be identified.
