This reaction involves the interaction of water with the mineral olivine in the upper mantle, producing hydrogen gas. Subsequent Fischer-Tropsch-type reactions can then convert this hydrogen and carbon dioxide into short-chain hydrocarbons.
Abiotic Oil Renewable Energy Revolution Beneath: The Science and Potential of Deep Hydrocarbons
Unlike conventional petroleum, which originates from the thermal maturation of kerogen, abiotic oil proposes that methane and heavier hydrocarbons generate independently of biological precursors under extreme pressure and temperature conditions. Economic and Industry Implications If abiotic oil were proven to be a significant and accessible resource, it would fundamentally alter global energy economics.
Proponents suggest that deep microbial processes or catalytic reactions involving iron oxides and water facilitate the conversion of carbon monoxide and hydrogen into complex hydrocarbons, a process sometimes referred to as the serpentization of olivine. The theory gained traction from the work of Russian and Ukrainian scientists in the mid-20th century, who argued that petroleum migrates from the mantle toward the crust via fissures and faults.
Abiotic Oil: The Renewable Energy Revolution Beneath
The Role of Serpentinization One of the most credible chemical pathways for abiotic hydrocarbon formation is serpentinization. The deep rock samples required for verification are difficult and expensive to obtain, and contamination from surface hydrocarbons is a persistent methodological concern.
