IMPROVING SPECTRAL ANALYSIS METHODS BY USING COMBINED METHODS

摘要

The present disclosure relates to borehole logging methods and apparatuses for estimating at least one parameter of interest of a volume of interest of an earth formation using nuclear radiation. The method may include obtaining an energy spectrum; using at least one processor to remove at least one energy spectrum component using a method selected from a spectral decomposition and spectral windows method; and estimating the concentration of at least one radionuclide using the energy spectrum after the removal. The estimation of the at least one radionuclide concentration may include using the other of the method selected form the removal. The apparatus may include at least one processor configured to perform the method.
