what does permeable rocks mean?

Answer 1

i believe it means they're not waterproof - ie water can sink into them
Permeable: measure of a rock’s ability to flow liquids or gases. Highly permeable rocks tend to have many large and well-connected pores. The more permeable the rock, the easier it is to produce oil and gas from the reservoir.

Answer 2

Permeable Rock

Answer 3

The permeability is the ability for a rock to transmit a fluid (water, oil, organic gas, H2S, CO2, Helium, mercury...) through a given volume of this rock.
The permeability of a rock is given for a given fluid.
In addition, in fractured rocks, one must differ vertical permeability from the horizontal permeability. The fluid is moving more easily in one plane than in the other.
It is measured in darcy usually or more often in millidarcy. The sand of a beach has a permeability around 0.1 to 2 darcy.

Answer 4

Permeable rocks contain tiny pores that allow fluids like water, oil and gas to filter through.

Impermeable rocks are solid and don't let fluids pass through.

Here's a bit more info for you.

This is what happens in petroleum formations deep under ground. The crude oil, gas and water are contained within the pores of the rock.
While the oil and gas were forming in the rock beds, it also tended to move (migrate) in an upward direction. This takes place from the source bed rocks through permeable porous rocks. Water, Oil & Gas move under the same forces, but in slightly different directions, Gas is much less dense than oil, and oil is less dense than water, so there is tendency for the gas and oil to move upwards through the water.

This upward movement of the components (water, oil and gas) continues, until the petroleum becomes trapped under an impermeable layer (or Cap Rock). It then flows along under this impermeable cap layer, until it reaches a position from which it cannot move any further, and becomes trapped. Migration continues and the Oil and Gas build up pressure under the cap rock. Oil and gas may also be trapped by another formation like a fault, which has a non-permeable surface.

One example of an disadvantage of a river being surrounded by permeable chalk is that the land can get eroded because its permeable; if rocks are permeable, it means that they can wear out very easily. If the lands near the river erode, this can lead to loss of property such as farmlands being eroded. This can be done by a process called SOLUTION (soluble particles dissolving into the river). Even if the rocks surrounding a river is impermiable clay and sand, this can lead to ABRASION (rocks carried along by the river wearing down the river bed and banks). and erosion can occur.

Answer 8

It means that water can pass through.

In the earth sciences, permeability (commonly symbolized as κ, or k) is a measure of the ability of a material (typically, a rock or unconsolidated material) to transmit fluids. It is of great importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs, and of groundwater in aquifers.

capable of being permeated : PENETRABLE; especially : having pores or openings that permit liquids or gases to pass through

Answer 9

permeable rocks are rocks that ables water to pass through them...

Answer 10

a rock that water ond other fluids can flow through, via pore spaces, fractures, bedding planes, layer boundaries and faults.
most sedimentary rocks are permeable.
