Multimineral analysis

Definition

Multimineral analysis is a geophysical technique used to identify and quantify multiple minerals present in a geological sample or reservoir. This analysis helps in understanding the mineral composition, which is crucial for effective reservoir characterization and groundwater studies, as it influences porosity, permeability, and fluid flow characteristics.
