What is one method NOT typically used for producing natural gas?

Landfilling is not typically used for producing natural gas. Natural gas is primarily extracted from the earth through methods such as drilling and fracking, which involve accessing gas reservoirs in underground formations. Drilling involves creating a borehole to reach the gas, while fracking entails injecting high-pressure fluids into the rock formation to release trapped gas.

Coal gasification, while not as common in contemporary natural gas production, is a process used to convert coal into synthetic natural gas. This process can produce gas that is chemically similar to natural gas but differs from the conventional extraction methods.

In contrast, landfilling refers to the disposal of waste materials in a designated area, where organic waste can decompose anaerobically (without oxygen) to produce landfill gas—a mixture primarily composed of methane and carbon dioxide. While this gas is similar to natural gas and can be harnessed for energy, the primary purpose of landfilling is waste management rather than natural gas production. Therefore, it is not considered a conventional method for producing natural gas.
