Can a rock have high porosity but low permeability?
Yes, it is possible for a rock to have high porosity, meaning it has a lot of open spaces or pores, but low permeability, indicating that the pores are not well connected or that the rock's structure hinders the flow of fluids. As a result, while the rock can hold a lot of fluid within its pores, the fluid may not be able to flow easily through it.
What would you expect to have the greatest porosity?
Sedimentary rock, especially sandstone, is expected to have the greatest porosity due to its formation process involving the accumulation of loose grains that leave spaces between them where fluids can reside. This high porosity allows for the storage and movement of fluids such as water, oil, or gas within the rock.
Which characteristic is absolutely necessary for a sedimentary rock to have potential as a possible reservoir rock for oil or gas?
The most critical characteristic for a sedimentary rock to serve as a potential reservoir rock for oil or gas is its porosity. This refers to the amount of open space within the rock that can hold fluids. Without sufficient porosity, the rock cannot store significant amounts of oil or gas.
Is shale rock high or low density?
Shale rock is generally considered to have a medium to high density, ranging from 2.6 to 2.8 g/cm3. Its density is influenced by the composition and porosity of the rock.
What is the definition of terms in porosity?
Porosity is a measure of the void spaces in a material, typically expressed as a percentage of total volume. It indicates the amount of pore space available for fluids to flow through a substance, such as rock or soil. High porosity allows for greater fluid flow, while low porosity restricts fluid movement.
How does sorting of rock particles affect porosity of rocks?
poorly sorted = low porosity well sorted = high porosity
Which factor is most important in determining how much groundwater can be stored in underground rock?
The porosity of the rock is the most important factor in determining how much groundwater can be stored in underground rock. Porosity refers to the amount of empty space within the rock that can be filled with water. Rocks with high porosity can store more groundwater.
Can a rock have high porosity but low permeability?
Yes, it is possible for a rock to have high porosity, meaning it has a lot of open spaces or pores, but low permeability, indicating that the pores are not well connected or that the rock's structure hinders the flow of fluids. As a result, while the rock can hold a lot of fluid within its pores, the fluid may not be able to flow easily through it.
What is low porosity and high porosity?
big particles=low porosity small particles=high porosity
What is a lightweight rock that floats?
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
How quickly would groundwater flow through rock with porosity and high permeability?
75
What are two factors about the particles in a rock have the greatest effect on the porosity of the rock?
Porosity refers to the measure of how much of a rock is open space. The two factors concerning particles in a rock that have the greatest effect on the rock's porosity are shape and distribution.
Why does a rock layer containing same sized particles have high porosity?
it is simply pie. the answer is pe
The percentage of a rock's total volume taken up by pore space is called the?
porosity of the rock.
What p means that the rock can absorb water?
The term "porosity" refers to the ability of a rock to absorb water. Rocks with high porosity have more open spaces available for water storage, while rocks with low porosity have fewer open spaces, limiting their ability to absorb water.
What is rock porosity?
Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%.
What would you expect to have the greatest porosity?
Sedimentary rock, especially sandstone, is expected to have the greatest porosity due to its formation process involving the accumulation of loose grains that leave spaces between them where fluids can reside. This high porosity allows for the storage and movement of fluids such as water, oil, or gas within the rock.
