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.
What is the name of the process of the ability of water to pass through a rock?
Porosity or permeability .
How quickly would groundwater flow through rock with porosity and high permeability?
75
What is a geological reservoir?
A geological reservoir is a lithology unit(comprising of sandstones, limestone and others), which keeps hydrocarbon reserves. This reservoir has its own porosity and permeability.
1 What characteristics of a rock layer allow it to hold water?
Permeability is the ability of that water to be transmitted from one place to another. For example clays have a huge porosity, but very bad permeability. Secondary permeability is the measure of other physical structures in a rock or admixture that allows for storage of water in spaces not primary to the fabric of the formation.
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.
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 are the porosity and permeability of Antarctic soil?
idks
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.
What is an accurate description of clay soil?
high porosity, low permeability
Which is an accurate description of sandy soil?
moderate 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.
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.
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.
What are the petrophysical parameters used in basin analysis?
porosity permeability fluid saturation
