Natural Gas Basics

The main ingredient in natural gas is methane, a gas (or compound) composed of one carbon atom and four hydrogen atoms. Once the natural gas wells are drilled and completed gas flows up through the well to the surface of the ground and into large pipelines. Some of the gases that are produced along with methane, such as butane and propane (also known as “by-products”) are separated and cleaned at a gas processing plant. Because natural gas is colorless, odorless and tasteless, mercaptan (a chemical that smells like sulfur) is added before distribution, to give it a distinct unpleasant odor (it smells like rotten eggs).

How Natural Gas Is Used

Natural gas is used to produce steel, glass, paper, clothing, brick, electricity and as an essential raw material for many common products. Some products that use natural gas as a raw material are: paints, fertilizer, plastics, antifreeze, dyes, photographic film, medicines, and explosives.

Slightly more than half of the homes in the United States use natural gas as their main heating fuel. Natural gas is also used in the homes to fuel stoves, water heaters, clothes dryers, and other household appliances.

Natural Gas Is a Major Energy Source for the United States

In 2010, there were 487,627 natural gas wells producing in 33 different states. Each year +/-17,000 new natural gas wells are drilled and competed in the U.S.A. About 25% of energy used in the United States came from natural gas in 2011. The United States used 23.78 trillion cubic feet (Tcf) of natural gas in 2010.
