What kind of rock is oil found in?

    Petroleum crude oil is often found in reservoir rocks, porous rocks where the oil is trapped. The oil can be found in a variety of bituminous, sedimentary rocks. Shale, sandstone and limestone are examples of sedimentary rocks that oil comes from and are found in.

    Oil can also be found in fractured volcanic rocks and fractured granite, and in the debris eroded from granitic uplifts. It can be found almost anywhere the conditions of porosity and permeability and source and trap are correct. But the other answer is correct in saying that limestones and sandstones, and to a lesser extent shales, are the kinds of rocks that most often serve as oil reservoir rocks.
