Better said, the ratio of the volumes occupied by two components, or by one component to the total volume of the system.This log usually has the unit 'Porosity'. This is the pore volume per unit gross volume. Porosity is determined from measurements on cores or interpreted from logs. Data from this log can be used to investigate the porosity of the formation.
