What is and where does natural gas come from?

What is and where does gas come from? Natural gas may be a fossil energy source that, like coal or oil, is formed from a mix of hydrocarbons, molecules formed by carbon and hydrogen atoms. Complex studies of geology and physics allow to seek out and exploit the gas deposits that many thousands of years of bacterial action have generated underground. Methane (CH4) is that the main component of gas , although it also contains other light hydrocarbons like ethane (C2H6), propane (C3H8), butane (C4H10) or pentane (C5H12) to a way lesser extent. Usually, it's found during a proportion of 85%, mixed with 10% ethane, 3% propane, 0.1% butane and 0.7% nitrogen. All have a really low boiling point, up to -158.9 ° C within the case of methane. While hydrocarbons with 5-10 carbon atoms are liquid at ordinary temperatures, these hydrocarbons of lower relative molecular mass (less than 5 carbons) are within the sort of gas or steam. To extract the energy contained wi...
