Description
Petroleum,also known as crude oil,or simply oil,is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons,and is found in geological formations. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel,petroleum is formed when large quantities of dead organisms,mostly zooplankton and algae,are buried underneath sedimentary rock and subjected to both prolonged heat and pressure.
