📖 Key Information

# Petroleum **Petroleum**, commonly referred to as **crude oil** or simply **oil**, is a naturally occurring, yellowish-black liquid mixture of organic compounds found in various geological formations beneath the Earth's surface. It is primarily composed of hydrocarbons, though it may also contain small amounts of nitrogen, oxygen, and sulfur. ## Definition and Scope The term "petroleum" encompasses two distinct states of the substance: * **Unprocessed Crude Oil:** The raw, naturally occurring liquid as it is extracted from the ground. * **Petroleum Products:** The derivatives resulting from the refining and processing of crude oil, such as gasoline, diesel, and kerosene. ## Formation and Origin Petroleum is classified as a **fossil fuel**. Its formation is a geological process spanning millions of years, originating from the following stages: 1. **Organic Accumulation:** The process begins with the remains of prehistoric organisms, predominantly microscopic **plankton and algae**, which settle on the bottom of ancient oceans and lakes. 2. **Sedimentation:** Over time, these organic materials are buried under heavy layers of sediment, such as mud and silt. 3. **Anaerobic Decay:** In an oxygen-depleted (anaerobic) environment, the organic matter is subjected to intense heat and pressure. 4. **Chemical Transformation:** Through these geothermal processes, the organic matter undergoes a slow chemical change, eventually transforming into the liquid hydrocarbons identified as petroleum.
