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… Web8 Apr 2024 · The porosity–permeability characteristics of this kind of igneous rocks were equivalent to state that was intermediate between the 1 st and 3 rd subtypes.

In dual-porosity reservoirs, the secondary porosity (e.g., isolated pores, vugs, and fractures) may significantly influence the rock-pore distribution, but may be overlooked by acoustic-log measurements. This topic is the subject of ongoing research.

The fracture porosity, if present, is one of the contributions to the rock's porosity. The other porosity contributions are other sources of secondary porosity like vugs or vugular porosity, effective matrix porosity, and non effective matrix porosity like clay …

WebDissolution of either grains or cements in a sandstone leads to the development of secondary porosity. In the 1970s and 1980s, many publications suggested that mineral dissolution was a key process whereby significant porosity could be created at depth.
