The specific composition varies dramatically depending on the source, which is why oils are classified as light or heavy, and sweet or sour. Depending on the reservoir's characteristics, oil may flow naturally to the surface under its own pressure, or it may require enhanced recovery techniques such as injecting water, steam, or gas to push the oil toward the well.

Global Significance and Market Dynamics. Sweet oils have low sulfur content, making them less corrosive and more desirable than sour oils, which contain higher sulfur levels and require more aggressive refining processes to meet environmental standards.
Once a reservoir is confirmed, drilling rigs create a well to access the oil. Petroleum oil, often simply referred to as oil, is a naturally occurring, yellow-to-black liquid found within geological formations beneath the Earth's surface.
