Peak Oil and Abiotic Oil

According to the International Energy Agency, demand for oil has in fact peaked in Organization for Economic Cooperation and Development member countries, 30 of the world's most developed nations. The agency's chief economist, Fatih Birol, estimates that because of advances in technology, the demand for petroleum in these developed nations probably will never return to the levels seen in 2007. However, despite the flat demand over the past two years in Europe, Japan, and the United States, the IEA predicts that burgeoning demand for oil in emerging markets such as China and India will offset any declines and that worldwide demand will continue to increase.

With demand growing, the concept of "peak oil"--the theory that the world's supply of accessible oil will reach a high point and then begin to decline--has many people worried and uncertain about oil's prospects. According to Gary Long, the Energy Information Agency's expert on crude oil reserves, while the world supply is finite, there's very little consensus about how much is left or how much technology will progress to extract difficult-to-obtain reserves. But what happens in the future will depend on the available alternatives, Long says. [1]

Abiogenic petroleum origin is a hypothesis that was proposed as an alternative to theory of biological petroleum origin. It was relatively popular in the past, but it became largely forgotten at the end of the 20th century after it failed to predict the location of new wells.

The abiogenic hypothesis argues that petroleum was formed from deep carbon deposits, perhaps dating to the formation of the Earth. Supporters of the abiogenic hypothesis suggest that a great deal more petroleum exists on Earth than commonly thought, and that petroleum may originate from carbon-bearing fluids that migrate upward from the mantle. The presence of methane on Saturn's moon Titan and in the atmospheres of Jupiter, Saturn, Uranus and Neptune is cited[1] as evidence of the formation of hydrocarbons without biology.

The biogenic theory for petroleum was first proposed by Georg Agricola in the 16th century and various abiogenic hypotheses were proposed in the 19th century, most notably by Alexander von Humboldt, the Russian chemist Dmitri Mendeleev and the French chemist Marcellin Berthelot. Abiogenic hypotheses were revived in the last half of the 20th century by Russian and Ukrainian scientists, who had little influence outside the Soviet Union because most of their research was published in their native languages. The theory was re-defined and made popular in the West by Thomas Gold, who published all his research in English.[2]

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.

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 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.

It appears that, unbeknownst to Westerners, there have actually been, for quite some time now, two competing theories concerning the origins of petroleum. One theory claims that oil is an organic 'fossil fuel' deposited in finite quantities near the planet's surface. The other theory claims that oil is continuously generated by natural processes in the Earth's magma. One theory is backed by a massive body of research representing fifty years of intense scientific inquiry. The other theory is an unproven relic of the eighteenth century. One theory anticipates deep oil reserves, refillable oil fields, migratory oil systems, deep sources of generation, and the spontaneous venting of gas and oil. The other theory has a difficult time explaining any such documented phenomena.

So which theory have we in the West, in our infinite wisdom, chosen to embrace? Why, the fundamentally absurd 'Fossil Fuel' theory, of course -- the same theory that the 'Peak Oil' doomsday warnings are based on.[3]

The conventional theory of petroleum formation connects oil with the process of sedimentation. And, indeed, nearly all of the oil that has been discovered over the past century-and-a-half is associated with sedimentary rocks. On the other hand, it isnít difficult to find rocks that once existed at great depths where, according the theories of Gold and the Russians, conditions should have been perfect for abiotic oil formation or the accumulation of primordial petroleum - but such rocks typically contain no traces of hydrocarbons. In the very rare instances where small amounts of hydrocarbons are seen in igneous or metamorphic rocks, the latter are invariably found near hydrocarbon-bearing sedimentary rocks, and the hydrocarbons in both types of rock contain identical biomarkers (more on that subject below); the simplest explanation in those cases is that the hydrocarbons migrated from the sedimentary rocks to the igneous-metamorphic rocks.

A significant reservoir of crude oil was discovered nearby in the late '60s, and by 1970, a platform named Eugene 330 was busily producing about 15,000 barrels a day of high-quality crude oil. By the late '80s, the platform's production had slipped to less than 4,000 barrels per day, and was considered pumped out. Done. Suddenly, in 1990, production soared back to 15,000 barrels a day, and the reserves which had been estimated at 60 million barrels in the '70s, were recalculated at 400 million barrels. Interestingly, the measured geological age of the new oil was quantifiably different than the oil pumped in the '70s. Analysis of seismic recordings revealed the presence of a "deep fault" at the base of the Eugene Island reservoir which was gushing up a river of oil from some deeper and previously unknown source.

Production from Eugene Island had achieved 20,000 barrels per day by 1989; by 1992 it had slipped to 15,000 b/d, but recovered to reach a peak of 30,000 b/d in 1996. Production from the reservoir has dropped steadily since then.

 

The evidence at Eugene Island suggests the existence of deep source rocks from which the reservoir is indeed very slowly refilling - but geologists working there do not hypothesize a primordial origin for the oil. In "Oil and Gas - 'Renewable Resources'?" Kathy Blanchard of PNL writes, "Recent geochemical research at Woods Hole Oceanographic Institution has demonstrated that the wide range in composition of the oils in different reservoirs of the Eugene Island 330 field can be related to one another and to a deeper source rock of Jurassic-Early Cretaceous age." (10) Her article explains that this kind of migration from nearby source rocks is hardly unique, and discusses it in the context of conventional biotic theory.

A technical paper by David S. Holland, et al., "Eugene Island Block 330 Field - U.S.A. Offshore Louisiana," published by AAPG, notes that the Eugene Island oils show abundant evidence of long-distance vertical migration. Based on a variety of biomarker and gasoline-range maturity indicators, these oils are estimated to have been generated at depths of 4572 to 4877 m (15,000 to 16,000 ft) at vitrinite reflectance maturities of 0.08 to 1.0% and temperatures of 150 to 170C (300 to 340F). Their presence in shallow, thermally immature reservoirs requires significant vertical migration. This is illustrated on Figure 36, which represents a burial and maturation history for the field at the time of petroleum migration, that is, at the end of Trimosina "A" time approximately 500,000 years ago.

A plot of the present measured maturity values versus depth is superimposed on the calculated maturity profile for Trimosina "A" time to illustrate the close agreement between measured and predicted maturity profiles. The clear discrepancy between reservoir maturity and oil maturity is striking and suggests that the oil migrated more than 3650 m (12,000 ft) from a deep, possibly upper Miocene, source facies. Petroleum migration along faults is indicated based on the observed temperature and hydrocarbon anomalies at the surface and the distribution of pay in the subsurface. These results are consistent with those of Young et al. (1977), who concluded that most Gulf of Mexico oils originated 2438 to 3350 m (8000 to 11,000 ft) deeper than their reservoirs, from source beds 5 to 9 million years older than the reservoirs[4]
