This log is a measure of the formation’s bulk density and is mostly used as a porosity measure. Different lithologies can also be determined using Density log based on returned density value. For example, pure quartz will have a bulk density (g/cm-3) up to 2.65, coal 1.2-1.8, halite 2.05, limestone up to 2.75, dolomite up to 2.87, anhydrite 2.98.
Density is mostly commonly used in conjunction with Neutron logs to determine lithology of formation (density-neutron suites such as Schlumberger FDC-CNL suite).
