Crude oil is obtained from between underground layers of sedimentary rocks.

Crude oil can ignite and burn at temperatures above 150°C (300°F). The exact temperature can vary depending on the specific composition of the crude oil.

Refined Crude Oil
Crude oil is excavated by drilling wells into underground reservoirs where the oil is trapped. Once a well is drilled, the pressure underground allows the oil to flow up through the well to the surface. The oil is then collected and transported for refining.
Yes, crude oil can burn. When ignited, it releases energy in the form of heat and light through combustion. However, burning crude oil releases pollutants into the atmosphere, contributing to air pollution and climate change.
Yes, crude oil can ignite and burn if exposed to a sufficient heat source, such as a flame or spark. The ignition temperature of crude oil varies depending on its composition, but typically ranges from around 400 to 600 degrees Fahrenheit. Once ignited, crude oil can burn vigorously and release heat and smoke.
"Petroleum" products are distilled from crude oil, so what comes out of the ground is crude oil.
Crude oil is formed over millions of years when organic matter, such as dead plants and animals, are buried deep underground and subjected to heat and pressure. This process, known as diagenesis, transforms the organic material into hydrocarbons, which make up crude oil. The oil can then be extracted from underground reservoirs using drilling techniques.
It is difficult to determine the exact amount of crude oil left underground due to factors such as varying estimates, technological advancements, and new discoveries. Estimates suggest that there are trillions of barrels of oil still remaining in underground reservoirs around the world.
