Abstract
A profile is produced based on measured survey data, where the profile contains indications corresponding to refraction events at different depths in a subterranean structure. Based on the profile and a critical angle model that correlates different concentrations of a given material to respective critical angles, a quantity of the given material in a subterranean structure at a particular depth is determined.
