Porosity or permeability .
Yes, it can have porosity, or pore spaces, but may not have permeability, or the ability for a fluid to flow through connected pore spaces.
permeability
Porosity is a measure how hole many pores, or holes a rock has in it. Permeability is a measure of how a rock resists fluids flowing through it. If a rock is very porous and is very permeable, water will pass right through it. Limestone is a good example. If the reverse is true, water will not flow through. Marble or Granite are good examples.

Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
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.
Porosity or permeability .
Porosity and permeability of the rock or soil is how water moves.
Some soils have a large volume of pore space,but the individual pores are too small to allowwater to pass through.
Porosity--the ability of water to move through the soil Permeability--the abiity of roots to reach into the soil Where water goes, roots can follow. If water cannot penetrate the soil, roots won't either.
The word is spelled 'Permeability'. Porosity means something can take water into itself but Permeable means it will allow water to pass through it
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.
This is porosity. You might also say that the soil is free-draining.
"Porosity is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock.""Permeability is a measure of the ease with which a fluid (water in this case) can move through a porous rock."Porosity becomes useful to know when, say, you want to determine how quickly a chemical spill might enter an underground water supply.Hope this helps.
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.
