Is the water table below the layer of impermeable rock?

If the layer of impermeable rock is below the water table, then the water table is likely above the impermeable rock and the groundwater will be trapped above it. If the impermeable rock is above the water table, then the water table is likely below the impermeable rock layer and the groundwater will not be able to pass through it.

How does groundwater collect?

Groundwater collects when rainwater or surface water percolates through soil and rock layers until it reaches an impermeable layer, forming an underground reservoir. This reservoir can feed into wells, springs, and aquifers.


Water cannot pass through solid rock because it is?

Impermeable. The pores in solid rock are too small for water to flow through.


What type of sedimentary rock is impermeable?

Shale is the type of sedimentary rock that is impermeable.


How do permeable and impermeable rock layers contribute to the formation of a spring?

The water sinks through the ground through permeable rock and is concentrating when it arrives to impermeable rock. When due to erosion the impermeable rock carrying water is exposed, the water appears as a spring.


An example of the impermeable rock?

What is an oil and gas reservoir?

An oil and gas reservoir is a subsurface geological formation that contains significant accumulations of hydrocarbons, primarily oil and natural gas. These reservoirs are typically found in porous rock layers, where the hydrocarbons can be trapped by impermeable rock formations above, creating a seal. The efficiency of extraction from a reservoir depends on factors like its size, pressure, and the properties of the surrounding rock. Understanding these characteristics is crucial for successful exploration and production in the oil and gas industry.


What is a name of a rock that does not allow water to pass through?

An impermeable rock that does not allow water to pass through is called a impermeable rock, such as shale or clay. These rocks have very low porosity and permeability, preventing water from flowing through them.


What is the best reservoir rock?

Porous sandstone is a good reservoir rock for its porosity enables it to store the fluid (oil?) and also to allow easy release. Compare with oil shale, where the rock is very fine grained and will not release the fluid easily. Both would ideally be capped with an impermeable cap rock to constrain the oil.
