Method for determining elemental concentrations in spectral gamma ray logging

A method for determining the concentrations of elements within a geologic formation includes the use of an inversion algorithm that seeks to minimize a cost function (F). The method includes the use of an iterative process 200 that updates the calculated concentrations of each element at each iterat...
