The presence of these heavier hydrocarbons increases the overall energy density of the fuel and adds economic value beyond just the methane content. Propane (C3H8) and butane (C4H10) are also common constituents, particularly in natural gas liquids (NGLs).

While other components exist, the entire infrastructure of pipelines, storage facilities, and power plants is designed around the efficient transport and combustion of this primary constituent. Helium, while present in minute quantities, is often extracted from natural gas reserves because of its valuable industrial and medical applications.
Its presence requires rigorous removal processes to ensure safety and prevent the formation of sulfur dioxide during combustion, which causes acid rain. The specific balance of these trace elements is unique to each reservoir, requiring detailed analysis before the gas can be transported.

Another common non-hydrocarbon is nitrogen (N2). The composition is not static; it varies significantly depending on the geological formation from which it is extracted.
