Petroleum is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is a complex mixture of hydrocarbons, along with varying amounts of nitrogen, oxygen, and sulfur. Petroleum is a fossil fuel, meaning it was formed from the remains of ancient organisms, primarily zooplankton and algae, over millions of years.

The extraction of petroleum, known as oil drilling, typically involves sinking wells into reservoirs deep underground or offshore. Once extracted, crude oil is transported to refineries. At refineries, crude oil undergoes a process called fractional distillation, where it is heated and separated into various components based on their boiling points. These components, or fractions, include gasoline, kerosene, diesel fuel, lubricating oils, and asphalt.

Petroleum and its derivatives are vital to modern society, serving as a primary source of energy for transportation, heating, and electricity generation. It is also a key ingredient in the manufacturing of plastics, pharmaceuticals, fertilizers, and countless other industrial and consumer products. The global demand for petroleum drives significant economic activity but also raises environmental concerns related to extraction, transportation, and combustion, including greenhouse gas emissions and potential oil spills. Efforts are ongoing to develop alternative energy sources and improve the efficiency of petroleum use.
