Jun 19, 2014 · How Natural Gas Is Formed. Natural gas is a fossil fuel, like oil and coal, which releases pollution and global warming emissions when burned. Methane, the primary component of natural gas (or just "gas"), is itself a potent global warming pollutant, more than 80 times more powerful than carbon dioxide over a 20-year period. Like oil, gas is a ... They typically form in environments where muds, silts, and other sediments were deposited by gentle transporting currents and became compacted, as, for example, the deep-ocean floor, basins of shallow seas, river floodplains, and playas. Most shales occur in extensive sheets several metres thick, though some develop in lenticular formations.
