Porosity - Wikipedia
Porosity is a fraction between 0 and 1, typically ranging from less than 0.005 for solid granite to more than 0.5 for peat and clay. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it …
What is Porosity, Types and Causes of Porosity - Geology Hub
Porosity refers to the amount of empty space or voids within a material or substance. It is often expressed as a percentage of the total volume of the material, with the remaining percentage being occupied by the solid material. What cause Porosity?
Porosity Definition & Meaning - Merriam-Webster
2016年12月7日 · The meaning of POROSITY is the quality or state of being porous.
Porosity - an overview | ScienceDirect Topics
Porosity of reservoir rock is defined as the pore fraction of the rock—that is, the ratio of pore space volume to bulk volume of the rock. Porosity is usually expressed as a percentage: Fluid-productive sandstones display porosities ranging between 0.05 and 0.4, or 5%–40%.

Porosity is an intrinsic property of every material. It refers to the amount of empty space within a given material. In a soil or rock the porosity (empty space) exists between the grains of minerals. In a material like gravel the grains are large and there is lots of empty space between them since they don’t fit together very well.
What is Porosity? How It Affects Oil Exploration and Geology
2024年12月4日 · Porosity is refers to the proportion of pore volume about the overall volume of the rock or material and is typically expressed as a percentage. It is calculated as a fraction between 0 and 1, or as a percentage between 0% and 100%, representing the volume of voids relative to the total volume.
Porosity - an overview | ScienceDirect Topics
Porosity is a volumetric property of porous media, which indicates the volumetric ratio of the void space (pores, fractures, cracks) occupied in the unit volume of the porous medium. Therefore, the porosity of a reservoir is a measure of the ability of a reservoir to store fluid (oil, gas, and water). Porosity φ is determined, as follows:
Porosity - SpringerLink
Porosity is a fundamental property of material in general and geomaterials (soils and rocks) in particular, being used in many fields such as material science, earth science, hydrogeology, rock and soil mechanics, geotechnical and environmental engineering, petroleum geoscience and engineering etc. Porosity (∅) is a measure of the void space in ...

From the reservoir engineering standpoint, porosity is one of the most important rock properties, a measure of space available for storage of hydrocarbons. Quantitatively, porosity is the ratio of the pore volume to the total volume (bulk volume).
