Aquifers.
the aquifer collapse is caused when the porous spaces of the permeable rock are filled with air, weakening the layers of the aquifer, as water is removed during over mining.
The rocks must be like that so the petroleum can have somewhere to reside while underground, the more porous and permeable the host rock is, the more oil there well be in it, as long as there is oil in the area. think of it as trying to fill a bowl full of marbles with water. It fills a lot easier then the bowl filled with cement
permeable rocks
anything that is porous is capable of absorbing water
That's called an "aquifer" if it's naturally-occurring. But a "cistern" is a man-made with a waterproof lining. If it's a really big cistern, it's a "covered reservoir".

porous stone can, but non-porous stone like clay layers can't
C. A bowl filled with apples is the more porous of the four. Porosity is a function of the size of the fruit. The larger the fruit, the more porous the bowl will be (the more air or water that can be placed in the bowl). The smaller the fruit, the less porous the bowl will be. Compare with a bowl of stones and a bowl of sand. The stones are more porous because the sand can be more densely compacted, leaving very little room for water.
This type of layer is found within the earth and is called an Aquifer.

Because the molecular lattice is tighter and smaller than waters molecular lattice making it impermeable
* able to absorb fluids; "the partly porous walls of our digestive system"; "compactin the soil to make it less porous" * full of pores or vessels or holes == ==
An aquafer is an alternative term for an aquifer, an underground layer of waterbearing porous stone, earth or gravel.

In permeable (porous) rock layers like sandstone.
There is one called PORCERAX that is porous.
