Why Porosity From Density Log is Preferred Over Neutron Log

WebMar 14, 2024 · For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm 3, with a porosity that can vary from low to more than 30 percent. The density of quartz itself is 2.65 g/cm 3. If porosity were zero, the bulk density would equal the grain density. 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 b… office mondo 2016 kms 密钥
