Methods and systems for cuttings-based well logging, including a method that includes converting measurements of cuttings samples from one or more depth intervals of a wellbore to a concentration percent of one or more elements, determining a one or more minerals of the cuttings samples from the concentration percent and building a mineralogy model for the cuttings sample based at least in part on a gravimetric conversion of the concentration percent of at least some of the one or more elements to a concentration percent of the one or more minerals. The method further includes normalizing the concentration percent of the one or more minerals, computing a photo-electric absorption factor (PEF) of the cuttings samples for each of the one or more depth intervals, and presenting to a user a log of the computed PEF as a function of wellbore depth.
