Abstract:
A method for material evaluation may include detecting photons from gamma ray interactions with material in an annular region between a geological formation and a casing. An energy spectrum is generated from the detected photons. A difference between materials may then be detected based on a comparison of the generated energy spectrum with a reference spectrum for a known material (e.g., good cement, known fluid).

Claim (Index 17):
A system comprising:\n a downhole tool including a logging tool, the logging tool comprising:\n a gamma detector to detect photons resulting from photon interactions with material disposed in an annular region between a geological formation and a casing; and \n a controller coupled to the detector to generate digitized energy spectra based on detected photon count rates at different energy levels and to compare the generated energy spectra to reference spectra to evaluate the material in the annular region as compared to a reference material.
