Natural gas is one of the cleanest, safest, and most useful forms of energy in our day-to-day lives. Natural gas is a hydrocarbon, which means it is made up of compounds of hydrogen and carbon.The simplest hydrocarbon is methane; it contains one carbon atom and four hydrogen atoms.Natural gas can be found by itself or in association with oil.lberta s non-conventional natural gas potential includes coal bed methane (CBM), also known as natural gas in coal. The volume of this natural gas source, which is found in coal seams, is estimated to be about 500 Tcf of gas-in-place.
