The theory of Inorganic Origin of Petroleum (synonyms: abiogenic, abiotic, abyssal, endogenous, juvenile, mineral, primordial) states that petroleum and natural gas was formed by non-biological processes deep in the Earth, crust and mantle. This contradicts the traditional view that the oil would be a "fossil fuel" produced by remnants of ancient organisms. Oil is a hydrocarbon mixture in which the primary constituent is mainly methane CH₄ (a molecule composed of one carbon atom bonded to four hydrogen atoms). Occurrence of methane is common in Earth's interior, with the possible formation of hydrocarbons at great depths.

   The beginnings of this theory dates from the 19th Century when the French chemist Marcellin Berthelot and the Russian chemist Dmitri Mendeleev proposed to explain the origin of oil and their theories were revived in the decade after 1950.

   Hydrocarbons such as natural gas and oil are primordial materials i.e., were originally embedded to Earth during process of planetary accretion and have no intrinsic connection with biological material near the surface of the Earth. Several studies based on thermodynamics; experiments of high pressure-temperature; many evidences from geophysical, geochemical and geological data, combined with information from space probes and telescopes in Solar System and Universe have clearly demonstrated the abiotic origin of oil.
