What rock is low in porosity and low in permeability?
Most intrusive igneous rock is low in porosity and permeability.
What is an accurate description of clay soil?
high porosity, low permeability
Which is an accurate description of silty soil?
moderate porosity, low permeability
What is an accurate description of sandy soil?
moderate porosity, low permeability.
Porosity is the amount of pore space in soils. Permeability is the ability of water to pass through the soil. Why do some soils have high porosity but low permeability?
Some soils have a large volume of pore space,but the individual pores are too small to allowwater to pass through.

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.
How does sorting of rock particles affect porosity of rocks?
poorly sorted = low porosity well sorted = high porosity
Which is an accurate description of sandy soil?
moderate porosity, low permeability.
Which is an accurate description of silty soil?

What is low porosity and high porosity?
big particles=low porosity small particles=high porosity

Does silt have high permeability?
Silt has neither high or low permeability. It has moderate permeability. :) !

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.
