What is Natural Gas?

Natural gas is an organic mixture composed mainly of methane and hydrocarbon compounds. This gas occurs when the layered bodies of dead animals and plants are subject to high pressure and intense heat over a period of time. From this, the organic compounds of the bodies are reduced to two states: liquid and gas; with the former becoming highly-stressed from the constant pressure of the rock layers. This gas is an excellent source of clean, easy fuel because it's not only highly combustible, it is also produces less carbon dioxide than petroleum or coal and it burns cleaner than the previous mentioned products. Because of this factor, this gas is used a lot for powering electrical generators and steam turbines. Other times, both generators are combined to help power other ways to create a renewable energy, such as wind energy.
Where is the Gas and How is it Valued?
Most of the natural gas is caught in the shale layers of the Green River Formation and the Mesaverde Formation; other times there are pockets of natural gas in the mentioned formations. Due to the gas being mostly near aquifers and oil pockets, retrieving it can sometimes be difficult and/or dangerous if not carried out correctly. The reason for this concern is that the gas is pressurized from being under the strain of several rock layers over a period of time. Because natural gas is almost CO2 free, it is widely sought out due to its high combustibility; making it a perfect resource for powering structures and as a heating source for both residential and business districts.
