Crude Oil vs. Natural Gas: What's the Difference?
Edited by Harlon Moss || By Janet White || Updated on October 30, 2023
Crude oil is a liquid hydrocarbon, whereas natural gas is primarily methane in gaseous form.
Key Differences
Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits. Natural gas, on the other hand, is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but can include other hydrocarbons.
Crude oil is in a liquid state at room temperature and atmospheric pressure. Natural gas is gaseous under similar conditions. Both crude oil and natural gas can be found together in underground reservoirs, but their states differentiate them.
Crude oil is refined to produce a variety of products including gasoline, diesel, and jet fuel. Natural gas is primarily used for heating, electricity generation, and as a fuel for vehicles, especially after being compressed or liquefied.
When burned, crude oil releases more carbon dioxide compared to natural gas. Natural gas is often championed as a cleaner alternative to coal and crude oil because it emits fewer pollutants and has a lower carbon footprint.
The pricing mechanisms for crude oil and natural gas differ. Crude oil prices are often influenced by global events and supply-demand imbalances, while natural gas prices are more regionally influenced, reflecting transportation costs and local supply-demand conditions.
