Regular natural gas system maintenance has the added benefit of removing the risks associated with carbon monoxide buildup. On a global scale, gas is also safer for the environment than heating oil because natural gas emits 25% less carbon dioxide than oil.

As mentioned by Natural Gas SpecialistsMost often, vertical drilling is used to extract natural gas from the Earth's surface. The well can only extract as much gas as it can from a single vertical drill.
