Oil & Gas Are Found in What Kind of Rocks? | .Deze pagina vertalen

The types of rocks that contain oil and natural gas are all sedimentary rocks, rocks formed when grains and mineral particles deposited by running water fuse together. Because these rocks are cemented together from such small components, they are porous, full of spaces in which energy-rich carbon compounds can settle, later to be liberated in the form of either oil or gas.
