* Permeable rocks: This term emphasizes the ability of the rock to allow fluids (like water or oil) to pass through it.

* Reservoir rocks: This term is used in the context of oil and gas exploration and production, as these rocks hold and store hydrocarbons.

It's important to note that not all porous rocks are permeable. For example, a rock with many pores that are not connected would be porous but not permeable.
