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.
Porosity or permeability .

Percolation is the amount of water that enters soil during a given timeframe. Different soil types have different rates and the size of the particle affect how quickly the water will penetrate the water.

The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
Yes for example Clay has high porosity and low permeability
Most intrusive igneous rock is low in porosity and permeability.
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 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.

high porosity, low permeability
moderate porosity, low permeability.

moderate porosity, low permeability.
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.
