Bonjour !
La théorie du « pétrole abiotique » est assez crédible pour les russes et les ukrainiens car ils ont développé déjà plusieurs champs de pétrole à grande profondeur !!!!
De plus sur le blog du Centre Européen pour la Recherche et le développement des Nouvelles Technologies Energétiques Alternatives, il y a des articles sur « La théorie du pic pétrolier et déclin des énergies fossiles » dont un intitulé « Modele alternatif sur l’origine du petrole abiotique (non fossile) ». Voici quelques extraits en anglais :
Rock oil originates as tiny bodies of animals buried in the sediments which, under the influence of increased temperature and pressure acting during an unimaginably long period of time, transform into rock oil [petroleum, or crude oil]”Academician Mikhailo V. Lomonosov, « Slovo o reshdenii metallov ot tryaseniya zemli, » Proceedings of the Imperial Academy of Sciences, St. Petersburg, 1757.
The overwhelming preponderance of geological evidence compels the conclusion that crude oil and natural petroleum gas have no intrinsic connection with biological matter originating near the surface of the Earth. They are primordial materials which have been erupted from great depths.”Academician Professor Vladimir B. Porfir’yev, senior petroleum exploration geologist for the U.S.S.R., at the All-Union Conference on Petroleum and Petroleum Geology, Moscow, 1956.
Statistical thermodynamic analysis has established clearly that hydrocarbon molecules which comprise petroleum require very high pressures for their spontaneous formation, comparable to the pressures required for the same of diamond. In that sense, hydrocarbon molecules are the high-pressure polymorphs of the reduced carbon system as is diamond of elemental carbon. Any notion which might suggest that hydrocarbon molecules spontaneously evolve in the regimes of temperature and pressure characterized by the near-surface of the Earth, which are the regimes of methane creation and hydrocarbon destruction, does not even deserve consideration.”Professor Emmanuil B. Chekaliuk, at All-Union Conference on Petroleum and Petroleum Geology, Moscow, 1968.
The eleven major and one giant oil and gas fields here described have been discovered in a region which had, forty years ago, been condemned as possessing no potential for petroleum production. The exploration for these fields was conducted entirely according to the perspective of the modern Russian-Ukrainian theory of deep, abiotic petroleum origins. The drilling which resulted in these discoveries was extended purposely deep into the crystalline basement rock, and it is in that basement where the greatest part of the reserves exist. These reserves amount to at least 8,200M metric tons of recoverable oil and 100B cubic meters of recoverable gas, and are thereby comparable to those of the North Slope of Alaska. It is conservatively estimated that, when developed, these fields will provide approximately thirty percent of the energy needs of the industrial nation of Ukraine.”Professor Vladilen A. Krayushkin, Chairman of the Department of Petroleum Exploration, Institute of Geological Sciences, Ukrainian Academy of Sciences, Kiev, and leader of the project for the exploration of the northern flank of the Dnieper-Donets Basin, at the VII-th International Symposium on the Observation of the Continental Crust Through Drilling, Santa Fe, New Mexico, 1994.




·  The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not the work of any one single man, - nor of a few men. The modern theory was developed by hundreds of scientists in the (now former) U.S.S.R., including many of the finest geologists, geochemists, geophysicists, and thermodynamicists of that country. There have now been more than two generations of geologists, geophysicists, chemists, and other scientists in the U.S.S.R. who have worked upon and contributed to the development of the modern theory.(Kropotkin 1956 ; Anisimov, Vasilyev et al. 1959 ; Kudryavtsev 1959 ; Porfir’yev 1959 ; Kudryavtsev 1963 ; Raznitsyn 1963 ; Krayushkin 1965 ; Markevich 1966 ; Dolenko 1968 ; Dolenko 1971 ; Linetskii 1974 ; Letnikov, Karpov et al. 1977 ; Porfir’yev and Klochko 1981 ; Krayushkin 1984)ƒ

·  The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not a vague, qualitative hypothesis, but stands as a rigorous analytic theory within the mainstream of the modern physical sciences. In this respect, the modern theory differs fundamentally not only from the previous hypothesis of a biological origin of petroleum but also from all traditional geological hypotheses. Since the nineteenth century, knowledgeable physicists, chemists, thermodynamicists, and chemical engineers have regarded with grave reservations (if not outright disdain) the suggestion that highly reduced hydrocarbon molecules of high free enthalpy (the constituents of crude oil) might somehow evolve spontaneously from highly oxidized biogenic molecules of low free enthalpy. Beginning in 1964, Soviet scientists carried out extensive theoretical statistical thermodynamic analysis which established explicitly that the hypothesis of evolution of hydrocarbon molecules (except methane) from biogenic ones in the temperature and pressure regime of the Earth’s near-surface crust was glaringly in violation of the second law of thermodynamics. They also determined that the evolution of reduced hydrocarbon molecules requires pressures of magnitudes encountered at depths equal to such of the mantle of the Earth. During the second phase of its development, the modern theory of petroleum was entirely recast from a qualitative argument based upon a synthesis of many qualitative facts into a quantitative argument based upon the analytical arguments of quantum statistical mechanics and thermodynamic stability theory.(Chekaliuk 1967 ; Boiko 1968 ; Chekaliuk 1971 ; Chekaliuk and Kenney 1991 ; Kenney 1995) With the transformation of the modern theory from a synthetic geology theory arguing by persuasion into an analytical physical theory arguing by compulsion, petroleum geology entered the mainstream of modern science.

·  The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not controversial nor presently a matter of academic debate. The period of debate about this extensive body of knowledge has been over for approximately two decades(Simakov 1986). The modern theory is presently applied extensively throughout the former U.S.S.R. as the guiding perspective for petroleum exploration and development projects. There are presently more than 80 oil and gas fields in the Caspian district alone which were explored and developed by applying the perspective of the modern theory and which produce from the crystalline basement rock.(Krayushkin, Chebanenko et al. 1994) Similarly, such exploration in the western Siberia cratonic-rift sedimentary basin has developed 90 petroleum fields of which 80 produce either partly or entirely from the crystalline basement. The exploration and discoveries of the 11 major and 1 giant fields on the northern flank of the Dneiper-Donets basin have already been noted. There are presently deep drilling exploration projects under way in Azerbaijan, Tatarstan, and Asian Siberia directed to testing potential oil and gas reservoirs in the crystalline basement
