http://api.3m.com/density+and+porosity+relationship WebThe "density porosity" of the granite has no immediate meaning, scaled as it is to a limestone-porosity system. However, a simple backcalculation of the bulk density measurement gives an estimated density of about 2.6 gm/cc. A more extensive discussion of log properties will be made in the section on Igneous and Metamorphic Rocks.

Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the fraction of void space in the material, where the void may contain, for example, air or water. It is defined by the ratio: where VV is the volume of void-space (such as fluids) and VT is the total or bul…

Moreover, the shallow-reading density log frequently is an invaded-zone measurement, completely masking the gas effect on it. Because the neutron porosity is deeper reading, it is often the only log that can be used for gas detection. flowers associated with buddhaWebPhysical Properties Primer – Density, Volume and Porosity Density At first sight, density is a relatively straight forward term defined as mass divided by volume. On a lab scale, values are typically stated in g/cm3. However, there are multiple ways to define and quantify volume. Each gives rise to a different density parameter.
