As the development of the Sciences continued in the 19th century, the theory of fossil fuel was undermined by the work of such scientists as Marcellin Berthelot, Biasson and Sokolov and finally by Dmitri Mendeleev. For all intents and purposes they drove a stake through the heart of the fossil fuel theory. So what does happen?
The production of hydrocarbons is a continual process that takes place deep in the EarthÃ¢â‚¬â„¢s crust. It is the product of continuous high-temperature, high-pressure reactions between calcium carbonate and iron oxide in the presence of water. Calcium Carbonate (CaCO3) and Iron Oxide are two of the most abundant compounds making up the earthÃ¢â‚¬â„¢s crust. At temperatures of 1500Ã‚Â°C and pressures of 50,000 atmospheres, hydrocarbons are produced continuously. It seeps up through fissures in the earths crust until it is trapped in subterranean caverns. These trapped lakes of oil are what we call oil fields.
Hydrocarbons formation is actually dependant on atmospheric CO2. CO2 is absorbed by the oceans. When reacted with Calcium it can either be used by marine organisms to form shells or it can precipitate out as a fine powder. Both will find their way to the sea floor. These sediment layers will eventually form limestone. During plate tectonic motion one plate can be subducted (buried) under another. When this occurs at sea vast quantities of limestone (CaCO3) are buried deep in the EarthÃ¢â‚¬â„¢s crust.
This knowledge has been around for decades. The primary drive to develop a modern petroleum science came in the 1950Ã¢â‚¬â„¢s when the Soviet government was denied access to Western and Middle Eastern sources of oil. Russian and Ukrainian scientists called their work the abiotic or abiogenic theory of hydrocarbon formation. They have been extremely successful in finding oil deposits as far down in the crust as 13 km. The deepest that Westerners have drilled is 4.5km.
This article is merely to bring these facts to your attention. I recommend the links below for anyone who wishes to learn more. I will leave you with the thought that oil is the ultimate renewable energy. It is as valid as any other link in the carbon cycle of life
