Resumo: The natural gas used in Brazil is formed by a chain of hydrocarbons, mainly methane, in addition to gases in smaller proportions, such as ethane, propane, carbon dioxide, and nitrogen. It is a fossil fuel discovered in porous rocks derived from the organic matter of prehistoric animals and plants. The US calls natural gas shale gas. Its origin is from fossil residues identified in rocks with reduced porosity and permeability. The shale gas extraction method differs from the NG obtained in Brazil. CNG is measured in Brazil in volume (m3) and the US in Gallons of Gasoline Equivalent (GEG). The study points out measurement inconsistencies of CNG per volume (m3) and mathematics relates the amount paid in Reais for 1 m3 of CNG, in mass (kg), Gasoline Liter Equivalent (GLE), and Ethanol Liter Equivalent (ELE). Studies present an unreliable CNG measure in GLE or ELE and volume (m3) and recommend measuring CNG in mass (kg), in Brazil.
