Best Answer

Porosity is the amount of void space in a rock or other earth material (like a sand deposit) - in other words, it´s how much water a material can hold.

Permeability refers to how well water flows through a material - that´s controlled by how large the pores are, and how well connected they are.

How does porosity and permeability interact?

The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.


What is the difference between premeability and porosity?

The word is spelled 'Permeability'. Porosity means something can take water into itself but Permeable means it will allow water to pass through it


Can a rock have high porosity but low permeability?

Yes for example Clay has high porosity and low permeability


What rock is low in porosity and low in permeability?

Most intrusive igneous rock is low in porosity and permeability.


What does high porosity and low permeability mean?

Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.

Compare the porosity and the permeability of an aquifer with the porosity and the permeability of a layer of shale beneath the aquifer?

The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.

How can man increase porosity and permeability in oil wells?

There is not feasible way to change the overall porosity and permeability in an oil field. However, it is possible in many cases to improve the porosity and permeability within the near wellbore region, where the change in pressure is the greatest. Injecting acid into a well, may slightlyincrease the porosity but sigmificantly improve the permeability, as it creates larger flow paths (also called worm holes) through the formation. Hydraulic fracturing will also stimulate a well, although the formation's permeability and porosity is unchanges. It makes it easier for oil to flow into the well, so its effect in the long run, is the same as if the near well bore region had higher permeability. Low permeability formations often produced by horizontal wells, which is similar to hydraulic fracturing- it is easier for the oil to flow to the well.
