The abiotic hypothesis posits that the full suite of hydrocarbons found in petroleum can either be generated in the mantle by abiogenic processes, [17] or by biological processing of those abiogenic hydrocarbons, and that the source-hydrocarbons of abiogenic origin can migrate out of the mantle into the crust until they escape to the surface or ...
He is the founding father of modern abiogenic theory for origin of petroleum, which states that some petroleum is formed from non-biological sources of hydrocarbons located deep in the Earth's crust and mantle. He graduated from Leningrad Mining Institute in 1922, obtained a Dr.Sc. in Geology and Mineralogy in 1936, and become professor in 1941.
Petroleum microbiology is a branch of microbiology that deals with the study of microorganisms that can metabolize or alter crude or refined petroleum products. These microorganisms, also called hydrocarbonoclastic microorganisms, can degrade hydrocarbons and, include a wide distribution of bacteria, methanogenic archaea , and some fungi .
Scientific opinion on the origin of oil and gas is that all natural oil and gas deposits on Earth are fossil fuels, and are therefore not abiogenic in origin. There are a few abiogenic petroleum theories which are still subject to ongoing research and which typically seek to explain the existence of smaller quantities of oil and gas.
The name that experts in the field use to refer to this theory is "abiogenic", not "abiotic". The conference is described here. Hyperion 01:20, 28 Jun 2004 (UTC) This presents an interesting dilemma. Google has 227 matches for "abiotic petroleum" and 144 for "abiogenic petroleum". With such a small sample size, how to determine which is more ...
Petroleum, or evidence of its immediate occurrence, can be found on the surface of the Earth. Oil seeps can be found near a fault zone, where the movement of Earth's crust can expose petroleum source rock, and thus the crude oil itself. [15] They can also be found on the ocean floor, and can be found using satellite imaging. [16]
However, later research disputed this interpretation of the data, stating that the observations may be better explained by abiotic processes in silica-rich waters, [79] "chemical gardens," [80] circulating hydrothermal fluids, [81] or volcanic ejecta. [82]
