Millions of years ago, tiny animals and plants died. They settled at the bottom of the oceans. Over time, they were crushed beneath layers of sediment that built up above them and eventually turned into rock. The organic matter, now trapped hundreds of metres below the surface, started to change. Under the action of gentle heat and pressure, and in the absence of air, the biological debris turned into oil and gas. Or so the story goes.

In 1951, however, a group of Soviet scientists led by Nikolai Kudryavtsev claimed that this theory of oil production was fiction. They suggested that hydrocarbons, the principal molecular constituents of oil, are generated deep within the earth from inorganic materials. Few people outside Russia listened. But one who did was J. F. Kenney, an American who today works for the Russian Academy of Sciences and is also chief executive of Gas Resources Corporation in Houston, Texas. He says it is nonsense to believe that oil derives from "squashed fish and putrefied cabbages." This is a brave claim to make when the overwhelming majority of petroleum geologists subscribe to the biological theory of origin. But Dr Kenney has evidence to support his argument.

In this week's Proceedings of the National Academy of Sciences, he claims to establish that it is energetically impossible for alkanes, one of the main types of hydrocarbon molecule in crude oil, to evolve from biological precursors at the depths where reservoirs have typically been found and plundered. He has developed a mathematical model incorporating quantum mechanics, statistics and thermodynamics which predicts the behaviour of a hydrocarbon system. The complex mixture of straight-chain and branched alkane molecules found in crude oil could, according to his calculations, have come into existence only at extremely high temperatures and pressures-far higher than those found in the earth's crust, where the orthodox theory claims they are formed.

To back up this idea, he has shown that a cocktail of alkanes (methane, hexane, octane and so on) similar to that in natural oil is produced when a mixture of calcium carbonate, water and iron oxide is heated to 1,500° C and crushed with the weight of 50,000 atmospheres. This experiment reproduces the conditions in the earth's upper mantle, 100 km below the surface, and so suggests that oil could be produced there from completely inorganic sources.

Kenney's theories, when discussed at all, are universally described as "new," "radical," and "controversial." In truth, however, Kenney's ideas are not new, nor original, nor radical. Though no one other than Kenney himself seems to want to talk about it, the arguments that he presented in the PNAS study are really just the tip of a very large iceberg of suppressed scientific research.

This story really begins in 1946, just after the close of World War II, which had illustrated quite effectively that oil was integral to waging modern, mechanized warfare. Stalin, recognizing the importance of oil, and recognizing also that the Soviet Union would have to be self sufficient, launched a massive scientific undertaking that has been compared, in its scale, to the Manhattan Project. The goal of the Soviet project was to study every aspect of petroleum, including how it is created, how reserves are generated, and how to best pursue petroleum exploration and extraction.

The challenge was taken up by a wide range of scientific disciplines, with hundreds of the top professionals in their fields contributing to the body of scientific research. By 1951, what has been called the Modern Russian-Ukrainian Theory of Deep, Abiotic Petroleum Origins was born. A healthy amount of scientific debate followed for the next couple of decades, during which time the theory, initially formulated by geologists, based on observational data, was validated through the rigorous quantitative work of chemists, physicists and thermodynamicists. For the last couple of decades, the theory has been accepted as established fact by virtually the entire scientific community of the (former) Soviet Union. It is backed up by literally thousands of published studies in prestigious, peer-reviewed scientific journals.

For over fifty years, Russian and Ukrainian scientists have added to this body of research and refined the Russian-Ukrainian theories. And for over fifty years, not a word of it has been published in the English language (except for a fairly recent, bastardized version published by astronomer Thomas Gold, who somehow forgot to credit the hundreds of scientists whose research he stole and then misrepresented).

This is not, by the way, just a theoretical model that the Russians and Ukrainians have established; the theories were put to practical use, resulting in the transformation of the Soviet Union - once regarded as having limited prospects, at best, for successful petroleum exploration - into a world-class petroleum producing, and exporting, nation.

J.F. Kenney spent some 15 years studying under some of the Russian and Ukrainian scientists who were key contributors to the modern petroleum theory. When Kenney speaks about petroleum origins, he is not speaking as some renegade scientist with a radical new theory; he is speaking to give voice to an entire community of scientists whose work has never been acknowledged in the West. Kenney writes passionately about that neglected body of research:

The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not new or recent. This theory was first enunciated by Professor Nikolai Kudryavtsev in 1951, almost a half century ago, (Kudryavtsev 1951) and has undergone extensive development, refinement, and application since its introduction. There have been more than four thousand articles published in the Soviet scientific journals, and many books, dealing with the modern theory. This writer is presently co-authoring a book upon the subject of the development and applications of the modern theory of petroleum for which the bibliography requires more than thirty pages.

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)

The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not untested or speculative. On the contrary, the modern theory was severely challenged by many traditionally-minded geologists at the time of its introduction; and during the first decade thenafter, the modern theory was thoroughly examined, extensively reviewed, powerfully debated, and rigorously tested. Every year following 1951, there were important scientific conferences organized in the U.S.S.R. to debate and evaluate the modern theory, its development, and its predictions. The All-Union conferences in petroleum and petroleum geology in the years 1952-1964/5 dealt particularly with this subject. (During the period when the modern theory was being subjected to extensive critical challenge and testing, a number of the men pointed out that there had never been any similar critical review or testing of the traditional hypothesis that petroleum might somehow have evolved spontaneously from biological detritus.)

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.
