Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

The oil flowed from the source rock and accumulated in thicker, more porous limestone or sandstone, called reservoir rock. Movements in the Earth trapped the petroleum oil and natural gas in the reservoir rocks between layers of impermeable rock, or cap rock, such as granite or marble.
