Natural Gas is actually formed similarly to crude oil! It’s incredible what intense heat and pressure can do, and in the case of natural gas, this fact is no exception.
The basis of the fossil fuel is made from decomposing plant and animal matter, which are then buried and exposed to varying amounts of pressure and heat over millions of years. The end product is what we today call Natural Gas.
Here’s where it gets more interesting.
Natural gas used to be an unwanted byproduct of oil drilling. As fluids from oil wells rise to the surface, they undergo various pressure changes on their way to the surface. Think of buying your favorite soft drink at the store and twisting the cap off. The same way that the soda “fizzes” from carbon dioxide bubbling to the surface is the same process that happens to natural gas as it reaches the surface.
This is just when natural gas is found in oil wells, though.
It can also be pumped from coal beds as well as isolated natural gas fields. It’s really found in a variety of underground wells around the world, which just goes to show how natural gas formation is so similar to how oil is formed.
And where exactly is the biggest natural gas reserve? Some say Russia has the largest reserves in the world, with the United States right behind them.
