    Coal bed methane is a gas, methane, that naturally occurs in coal seams. It is formed during the conversion of organic material to coal and becomes trapped in cleats in the coal seam. The coal bed methane is trapped in the coal seam in part by water pressure and in part by weak covalent bonding forces known as Van de Waals forces.
