terms:photon_log
A well log of scattered gamma rays differing from a density log in that the tool is not pressed against the borehole wall and hence is especially sensitive to changes in hole diameter or density of the fluid in the borehole. It has been used for determining changes in the density of fluids in the well bore and location of cement in the casing-formation annulus.
