The formation process of Crude Oil and Natural Gas - Petroleum (English: petroleum, through the Latin: petrus), also dubbed since the black gold is really a thick liquid, darkish or greenish flammable, which is perfectly located at the upper layers with the few areas in the earth's crust. Petroleum and natural gas from the ocean microorganisms, plants and animals that died about 150 million years ago. The remains of such organisms to stay around the sea bottom, then engrossed in mud. Layer of mud was gradually transformed into a layer of rock consuming pressure about it. Meanwhile, with increasing pressure and temperature, anaerobic bacteria describes the remains of such microorganisms and become gas and oil.
Particles oil and gas formation takes an incredible number of years. Oil and gas that seeped in rocks that formed because the water in porous rocks. Oil and coal may migrate in one region to a new, then terkosentrasi if blocked by an impermeable layer.
Although oil and natural gas are formed at the bottom on the ocean, many petroleum resources found in the mainland. This happens as the movement from the earth's crust, so a lot of the ocean towards the mainland.
