Abstract:
Soil gas measurements of radon (222Rn), CO2, and hydrocarbon concentrations, as well as gamma-ray spectrometry, were conducted at two separate locations to estimate the measurement results for known locations of hydrocarbon accumulations in the subsurface and oil seepage on the surface. The aim of the study was to confirm the applicability of the method for identifying migration pathways (e.g., faults) and to detect possible seepages of hydrocarbons to the surface as well as to investigate possible health issue potential about the soil gas analysis results. Site A investigations were performed with a large number of sampling points to provide sufficient spatial coverage to capture the influence of subsurface lithologic variability as well as the influence of the migration pathway on the measured parameters. For the investigation of site B, sampling points were positioned to reflect the situation between the area above producing hydrocarbon fields and areas with no confirmed accumulation. The results presented show that it is possible to distinguish the near-surface lithology (gamma-ray spectrometry), characterize the migration pathway, and indicate the area of oil seepage at the surface. Areas above the known hydrocarbon accumulations generally have elevated radon concentrations and detectable heavier hydrocarbons with sporadic methane in soil gas, which contrasts with the lower radon levels and lack of detectable heavier hydrocarbons in soil gas in the area with no confirmed hydrocarbon accumulation in the subsurface.

Abstract:
(Aero‐)magnetic anomalies have been reported from several commercial hydrocarbon accumulations. However, the processes responsible for such anomalies are relatively poorly understood. This paper conceptually discusses chemical and microbiological processes involved in generating anomalous magnetization related to hydrocarbon accumulations, including hydrocarbon seepage environments. Based on thermodynamic criteria and microbiologic activity, the formation and destruction of magnetic mineral assemblages can be predicted. Under the influence of hydrocarbons, magnetite and pyrrhotite are the most important magnetic minerals formed, and the most abundant magnetic mineral destroyed is hematite. Hence, the invasion of hydrocarbons may result in “positive,” “absent,” or “negative” magnetic contrasts relative to the total magnetization prior to hydrocarbon invasion, depending upon the amounts of authigenic magnetite and pyrrhotite formed relative to the amounts of hematite destroyed. Magnetism may be generated also by natural and anthropogenic processes that have no relationships to an underlying or adjacent hydrocarbon accumulation. Consequently, anomalous magnetization, even if associated with a hydrocarbon accumulation, may or may not be genetically related to it. Magnetic mineral assemblages and the resulting magnetic contrasts, such as those predicted in this paper, have been documented from some hydrocarbon seepage environments. Hence, anomalous magnetization can be used for hydrocarbon exploration in association with other surface exploration methods.

Abstract:
Geological analysis and physical analogy experiments indicate that, under geological conditions, hydrocarbon tends to migrate along a path of least resistance and attempt to follow the largest buoyancy component. There are four generalized modes of possible transport. First, hydrocarbons tends to migrate along the pathways with high porosity and permeability, and with a large grade difference relative to surrounding rocks (grade difference predominance); second, hydrocarbons tends to migrate in the opposite direction in overlying formations to the nadir of the sedimentation centre (divided syncline predominance); third, hydrocarbons tends to migrate in the direction of lower fluid pressure (fluid pressure predominance); fourth, hydrocarbons tends to migrate in the direction vertical to buoyancy (flow direction predominance). This paper reports on field observations in the Daqing oilfield area of China and also on physical analog experiments used to illuminate the four basic modes of transport. Under geological conditions, the hydrocarbon migration pathways are controlled by these four basic modes, which can be used to predict the directions of hydrocarbons migration and select favourable exploration locations.

Abstract:
Hydrocarbon migration patterns and pathways were studied on the basis of three-dimensional seismic interpretation, drilling, geochemistry, production performance, and other data. Using these findings, the main factors controlling hydrocarbon migration and accumulation in the Lower Paleozoic carbonate rocks of the Tazhong Uplift were discussed. The spatiotemporal relationship between the hydrocarbon kitchens and pathway systems of the Tazhong Uplift and the spatial pattern of pathway systems were considered the main factors causing differences in hydrocarbon enrichment. Results also revealed that the Lower Paleozoic carbonates of the Tazhong Uplift have two hydrocarbon accumulation systems (inside and outside the source rocks). For the accumulation system within the source rocks, hydrocarbon migration and enrichment are vertically differentiated. Middle Cambrian gypsum salt rocks serve as the boundary, above which thrust and strike-slip faults mainly allow vertical transport of hydrocarbons. A multistage superposition pattern of strike-slip faults controls the differences in hydrocarbon enrichment on the periphery of the fault zone. Beneath the gypsum-salt rocks, hydrocarbon migration and enrichment is controlled by the topography of paleostructures and paleogeomorphology. For the hydrocarbon accumulation system outside the source rocks, hydrocarbon migration and enrichment are restricted by the layered pathway system, and the topography of the paleostructures and paleogeomorphology is the key factor controlling hydrocarbon enrichment. The Tazhong No. 1 Fault is the main vertical pathway system in the area underlain by no source rocks, and hydrocarbons are enriched at the periphery of the Middle-Lower Cambrian and No. 1 Fault Zone.

Abstract:
The paper presents the results of the study of main factors determining conditions of formation and distribution of oil and gas deposits within the Cenozoic sedimentary cover and Precenozoic granite basement of the Vietnam shelf. The structural and tectonic model of the Kyulong basin constructed by the authors allows to reveal the conditions of formation of regional and local structures in the sedimentary cover containing hydrocarbon deposits; mechanisms of hydrocarbon traps emergence and hollow space (collectors); genesis of hydrocarbons, including the hydrocarbons existed in the basement rocks; the possible mechanism of migration and accumulation of hydrocarbons in the basement rocks. The traps which are real or potential reservoirs of hydrocarbons in the body of a crystal socle are widely developed. The structural and tectonic processes in the basement itself resulted in the development of positive morfostructures (domes, protrusions) the cores of which are made of disintegrated (granulated) rocks of a crystalline cap. In order to reconstruct the chronothermobaric conditions of occurrence and evolution of hydrocarbon generation centers and to restore the conditions of formation and distribution patterns of oil and gas accumulations on the shelf of Vietnam, three-dimensional modeling of generation and accumulation hydrocarbon systems was performed using the basin modeling technology and PetroMod software (Schlumberger, Ltd, USA). Studies of hydrocarbon biomarkers of oil fields in the Kyulong basin, including those located in the crystalline basement have shown the similarity of biomarker parameters of oil and organic matter, which demonstrates the organic nature of the oil fields of the basement on the shelf of Vietnam

Abstract:
A center in the present paper is referred to as an area or region which may include one or more hydrocarbon accumulations. A hydrocarbon generation center is referred to as an area containing high quality source rock which was subjected to thermal maturation. A gas generation center is an area in which an oil pool or accumulation was present, and oil was thermally cracked to generate gas. A gas accumulation center is referred to as an area in which natural gas generated from cracked oil accumulated. A gas preservation center is referred to as an area or region where the present natural gas pool/pools is/are located. As one of the oldest petroleum reservoir rocks in the world, the upper Sinian Dengying Formation (Upper Proterozoic) in the Sichuan basin was deeply buried, and its paleo-oil pools (gas generation centers) underwent complex transformation into paleo-gas pools (gas accumulation centers) and the present gas pools (gas preservation centers) as a result of multiphase tectonic activities. The paleo oil pools (gas generation centers) were the main hydrocarbon sources of the paleo gas pools (gas accumulation centers), which were in turn the main sources of hydrocarbons for today's (remaining) gas pools (gas preservation centers). The key factor in the oil accumulation was the presence of rich hydrocarbon source rocks (hydrocarbon generation centers) in the Early Cambrian strata and a good seal development. Being controlled by the early tectonics and sedimentary development of the basin, the hydrocarbon generation centers appeared to have been stationary in space, while in time the other three centers (gas generation centers, gas accumulation centers and gas preservation centers) migrated as result of tectonic events in the basin. Therefore, the time-spatial relationships between these “three centers” (gas generation centers, gas accumulation centers and gas preservation centers) decides the final distribution of natural gas in the Sichuan basin. Relationship between generation, accumulation and preservation of hydrocarbons in the marine carbonates buried deeper than 4500 m in the Sichuan basin, can be separated into: (1) an accumulation mode with the “three centers” being superimposed; (2) an accumulation mode with “the preservation center” disintegrated; (3) an accumulation mode with the “three centers” migrated for a short distance; (4) a destruction mode with the preservation center lost. The natural gas exploration of the upper Sinian carbonate rocks in the Sichuan basin can be most successful where the “three centers” overlap, such as at the front area of the Micang Mountains, which could be the most promising area for the future gas exploration.

Abstract:
The report is devoted to the study of conditions for the formation of organic porosity–void spaces of organic origin formed during transformation of the organic matter into hydrocarbons, and their role in the formation of hydrocarbon accumulation in low-permeability shale strata. The experience of studying and developing known shale formations of the world testifies to the fact that such strata are hybrid phenomena, that is, they are both oiland gas-bearing strata containing traditional and non-traditional accumulations of hydrocarbons. Based on the results of the programmed pyrolysis by the Rock-Eval-6 method, an estimate has been performed to quantify organic (kerogen) porosity. This estimate allows for determining the forecast retention volume of HCs generated during catagenesis.

Abstract:
Diverse types of marine carbonate reservoirs have been discovered in the Tazhong Uplift, Tarim Basin, and late alteration of such reservoirs is obvious. The marine source rocks of the Cambrian-lower Ordovician and the middle-upper Ordovician provided abundant oil and gas for hydrocarbon accumulation. The hydrocarbons filled various reservoirs in multiple stages to form different types of reservoirs from late Caledonian to early Hercynian, from late Hercynian to early Indosininan and from late Yanshanian to Himalayan. All these events greatly complicated hydrocarbon accumulation. An analysis of the discovered carbonate reservoirs in the Tazhong Uplift indicated that the development of a reservoir was controlled by subaerial weathering and freshwater leaching, sedimentation, early diagenesis, and alteration by deep fluids. According to the origin and lateral distribution of reservoir beds, the hydrocarbon accumulation zones in the Tazhong area were identified as: karsted reservoirs, reef/bank reservoirs, dolomite interior reservoirs, and hydrothermal reservoirs. Such carbonate hydrocarbon accumulation zones are distributed mainly in specific areas of the Tazhong uplift, respectively. Because of differences in the mechanism of reservoir formation, the reservoir space, capability, type and distribution of reservoirs are often different in different carbonate hydrocarbon accumulation zones.

Abstract:
We study the mechanisms of migration and spacial distribution of hydrocarbon deposits along a regional 1000 km long SW - NE seismic cross section of the South Caspian Basin. A retrospective 2D geological simulation of basin subsidence and sediment filling history is performed taking into account accompanying processes of thermal and catagenetic transformations of organic matter, and subsequent migration and accumulation of hydrocarbons. The start of the basin opening with accumulation of considerable sedimentary mass can be dated as middle Mesozoic (Triassic or Jurassic), and hydrocarbon prone horizons can now be located at depths of 12 km. The hydrocarbon saturation of the Pliocene Productive Series is of epigenetic (allochtonous) nature, which is also confirmed in literature by geochemical data from mud volcanoes and by other facts. Geochemical age, depth of provenance and reworking degree of hydrocarbons point at generation sources in Mesozoic (gas) and Paleogene-Miocene formations (oil) with only subordinate participation of the lower "Productive Series" Pliocene suites. The dominant migration pattern of fluids is interformational (interstratal) intermittent injective subvertical flow along disjunctive planes, zones of increased fracturing and loose rocks, diapir intrusion contacts, eruptives of mud volcanoes, lithofacial unconformities and other structures, breaking the rocks continuity. This implies the possibility of commercial-scale accumulations of hydrocarbons at ultra high depths, if trap structures of sufficiently large sizes are available, comparable with already discovered giant oil and gas fields (Shah-Deniz, Azeri-Chirag-Gyuneshli etc).

Abstract:
Les structures d’échappement de fluides et leurs mécanismes de migration à travers la pile sédimentaire sont un phénomène connu sur les marges continentales. Elles ont été largement étudiées depuis une vingtaine d’années, notamment en raison de l’amélioration de la résolution des données sismiques, et de l’abondance des données dans ces zones, du fait de la prospection pétrolière. Le bassin du Bas Congo, au large de l'Afrique de l’ouest, est une province pétrolière prolifique qui a été largement étudiée et qui est exploitée depuis plus de 30 ans. La zone d’intérêt est située au-dessus d'un champ pétrolier producteur (la zone de Moho), dans laquelle les hydrocarbures sont piégés dans des chenaux turbiditiques. Le travail est principalement basé sur l'analyse de données géophysiques comprenant de la sismique 3D et 2D-THR, de la bathymétrie multifaisceaux et la rétrodiffusion correspondante, ainsi que des données de fond (échantillons prélevés, photos ROV, analyses géochimiques). L'analyse de cet important jeu de données sismiques a révélé de nombreuses évidences de migration de fluides dans la pile sédimentaire mio-pliocène. Ces dernières correspondent principalement à des indices de migration focalisée de fluides, incluant des structures actuelles d’expulsion de fluides sur le fond de l’eau et des structures enfouies, interprétées comme fossiles, et indiquant une activité ancienne du système d’expulsion de fluides. Les indices de migrations de fluides étudiés correspondent principalement à des pockmarks (dépressions) et à des cimentations carbonatées. Ces deux types d’indices peuvent s’empiler sur plusieurs centaines de mètres, mettant en évidence la pérennité des échappements et suggérant le développement de véritables conduits.Un nouveau type de pockmarks a été mis en évidence, les structures en araignée, qui sont localisées au-dessus d'un réservoir turbiditique, et qui résultent d'une migration focalisée des hydrocarbures thermogéniques. Leur fonctionnement est lié aux hydrates de gaz dans le contexte d’un BSR penté (Bottom Simulating Reflector), du fait de la présence du biseau des hydrates. Un modèle dynamique de leur fonctionnement est développé, montrant que ces structures se développent vers l'amont de la pente, du fait de la migration du gaz sous le BSR penté. Une étude du BSR, dans le contexte particulier du biseau des hydrates, permet de proposer un modèle des échappements de gaz liés à la dissociation des hydrates, lors d'une baisse du niveau marin. Ce modèle met en scène une dissociation des hydrates de gaz d'échelle régionale (associée à du gaz biogénique), localisée au niveau du biseau des hydrates du dernier bas niveau marin. Enfin, le réseau de structures d’échappements de fluides de l’intervalle Mio-Pliocène a été investigué dans le but de comprendre son architecture et les mécanismes de migration de fluides dans la zone d’étude. Les hydrocarbures semblent migrer principalement le long de certaines portions de failles et verticalement à travers la pile sédimentaire sous forme de « pipes » ou de cheminées. La base du Pliocène, associée à une baisse du niveau marin, marque la formation des premières paléo-araignées ainsi que d'un niveau contenant de nombreux indices de présence de gaz. Un modèle de ce réseau de migrations de fluides est proposé, intégrant les chemins de migrations des hydrocarbures à travers la pile sédimentaire, et l’événement majeur de la base Pliocène. Cette étude semble indiquer que les phases de baisse du niveau marin constituent des déclencheurs pour la migrations des fluides dans les bassins.Ce travail marque ainsi le point de départ d'une investigation à plus grande échelle qui consiste d'une part à rechercher des structures similaires (araignées et bandes de pockmarks) dans d'autres bassins et d'autres part à comparer les événements d'échappement de fluides à la courbe eustatique
Evidence of fluid flow features and their mechanisms of migration through the sedimentary pile are a known phenomenon on continental margins. It has been widely studied over the past twenty years, notably due to the improved resolution of seismic data and the abundance of data in these areas due to oil and gas exploration.The Lower Congo basin, offshore West Africa, is a prolific petroleum province that has been extensively studied, and has been in operation for over 30 years. The area of interest is located above a producing oil field (the Moho license), in which hydrocarbons are trapped in turbidite channels. The work is primarily based on the analysis of geophysical data including 3D and 2D-THR seismic, multibeam bathymetry and corresponding backscatter, as well as background data (samples taken from ROV photos, geochemical analyses).The analysis of this important seismic dataset revealed abundant evidence of fluid migration in the Mio-Pliocene sedimentary pile. They mainly correspond to indications of vertically focused migration, including current fluid expulsion structures on the seafloor, and buried structures, interpreted as fossile and indicating former activity of the fluid expulsion system. The studied fluid migration features mainly consist of pockmarks (depressions) and carbonate cementations. These two types of indicators can build vertical stacks, over several hundred meters, highlighting the durability of the fluid escapes and suggesting the development of real pipes.A new type of pockmarks has been discovered, the spider structures, which are located above a turbiditic reservoir, and which result from a focused migration of thermogenic hydrocarbons. They are related to gas hydrates, in the context of a sloping BSR (Bottom Simulating Reflector), due to the presence of the hydrate wedge. A dynamic model of their functioning is proposed, showing that these structures develop upslope, due to the gas migration under the sloping BSR. A study of the BSR, in the particular context of the hydrates wedge, allows to propose a model of gas escapes, linked to the dissociation of the hydrates, during a sea level fall. This model presents a dissociation of gas hydrates of regional scale (associated with biogenic gas), localized at the gas hydrate wedge zone of the last lowstand. Finally, the network of fluid escape structures of the Mio-Pliocene interval was investigated in order to understand its architecture and the mechanisms of fluid migration in the study area. Hydrocarbons appear to migrate mainly along certain portions of faults and vertically crosscutting the sedimentary pile through pipes or chimneys. The base of the Pliocene, associated with a sea level fall, marks the formation of the first paleo-spiders, as well as a level containing numerous evidence of gas. A model of this network of fluid migrations is proposed, integrating the indicators of hydrocarbon migrations through the sedimentary pile, and the major event of the Pliocene base. This study seems to indicate that a the sea level fall constitute a trigger for the fluids migrations, in the basin.This work thus marks the starting point of a larger-scale investigation which consists in, on the one hand, searching for similar structures (spiders and bands of pockmarks) in other basins ; and, on the other hand, by comparing fluid flow events with the eustatic curve

O gÃs natural, cuja maior parte à constituÃda de metano, à um combustÃvel que vem se expandindo no mercado energÃtico global por possuir uma queima mais limpa que outros derivados petrolÃferos e por ser mais eficiente energeticamente. No entanto, ele possui como grande desvantagem frente a outros combustÃveis a dificuldade em ser armazenado devido a sua baixa densidade. Materiais microporosos vÃm sendo utilizados para aumentar tal densidade por meio da adsorÃÃo. No entanto, um dos problemas encontrados na utilizaÃÃo desses materiais se trata da diminuiÃÃo da capacidade adsortiva apÃs ciclos de carga e descarga de tanques de armazenamento. O estudo desse problema, porÃm, demanda um grande nÃmero de experimentos e uma aparelhagem relativamente sofisticada. Este trabalho propÃs a simulaÃÃo molecular como uma metodologia vÃlida a ser utilizada para o estudo da retenÃÃo de alcanos em carbono ativado e em oito estruturas metalorgÃnicas: IRMOF-1, ZIF-8, CuBTC, PCN-11, PCN-14, UiO-66, MIL-100 e MIL-101. Considerou-se o gÃs natural como uma mistura de metano (C1), etano (C2), propano (C3) e butano (C4) nas proporÃÃes de, respectivamente, 84,7:10:0,9:0,1. Para a validaÃÃo dos modelos utilizados nassimulaÃÃes, as isotermas simuladas de C1, C2, C3 e C4 foram ajustadas Ãs experimentais obtidas da literatura para cada um dos materiais. Foram entÃo realizadas isotermas multicomponentes e estudo de sÃtios de adsorÃÃo para o estudo da retenÃÃo de hidrocarbonetos e da influÃncia de fatores composicionais e estruturais nesse fenÃmeno. Observou-se que as MOFs MIL-100 e ZIF-8 sÃo as mais recomendadas para uso em tanques de GNA por critÃrios de capacidade, eficiÃncia adsortiva e estabilidade. Verificou-se ainda que MOFs que apresentam sÃtios de adsorÃÃo pouco dispersos apresentam uma maior tendÃncia à acumulaÃÃo de hidrocarbonetos.
Natural gas, which consists mostly of methane, is a fuel that has been expanding in the global energy market by having a cleaner burning than other petroleum derivatives and are more energy efficient. However, it has a great disadvantage compared to other fuels: it is difficult to be stored due to its low energy density. Microporous materials have been used to increase the energy density by adsorption. However, one of the problems encountered in using these materials it comes to the decrease in adsorption capacity after charge and discharge cycles of the storage tanks. The study of this problem, however, requires a large number of experiments and a relatively sophisticated equipment. This paper proposes themolecular simulation as a valid methodology to study the retention of alkanes in activated carbon, and eight metalorganic structures: IRMOF - 1, ZIF - 8, CuBTC, PCN- 11, PCN -14, UiO -66, MIL -100 and MIL- 101. We considered the natural gas as a mixture of methane (C1), ethane (C2), propane (C3) and butane (C4) in the proportions respectively 84,7:10:0,9:0,1. For the validation of the models used in the simulations, the simulated isotherms of C1, C2, C3 and C4 were adjusted to fit the experimental ones, obtained from the literature data for every material. Multicomponent isotherms were then performed, the retention of hydrocarbons were studied as well as the influence of compositional and structural factors to this phenomenon. We noticed that the MOFs MIL-100 and ZIF-8 are the most recommended to use in GNA tanks according to the criteria of capacity, adsorption efficiency and stability. We verified as well that MOFs that have adsorption sites too localized present a larger tendency to the accumulation of hydrocarbons.

Abstract:
The strength and durability of proton exchange membranes for use in fuel cells has received much attention recently due to the increased push for sustainable alternatives to the internal combustion engine. To be viable, these alternatives must have comparable lifetimes and power outputs to the internal combustion engines they replace. Chemical degradation was once viewed as the most common culprit of early fuel cell failure, but as membranes and catalysts improved, mechanical failure became an important factor. As a result, fundamental research on the mechanically-induced failure mechanisms of fuel cell membranes, coupled with development and processing of less expensive membranes, has become an important topic. The use of the blister test geometry, along with digital image correlation of the deformed shape, creates a self-contained analysis tool useful for measuring the biaxial strength of membranes. In this work, blister tests are used to measure biaxial stress and strain for fuel cell membranes subjected to ramped pressure loading to form stress-strain curves that indicate the onset of yielding under biaxial stress conditions. Stress-life curves are developed experimentally for Gore-Selec? series 57 members using data collected under constant pressure conditions. These results are used to predict blister failure under ramped and fatigue loadings. A newly implemented hydrocarbon membrane system is evaluated with constant-pressure-to-leak blister testing. Improved strength following an isothermal hold at 100°C (pretreatment) is shown to occur. Ramped pressure testing indicates that the material after the pretreatment is stiffer and has a higher yield stress than the material before treatment. Morphological and constitutive characterization indicated differences in the materials that are consistent with the improved performance.

From the Proceedings of the 1988 Meetings of the Arizona Section - American Water Resources Association and the Hydrology Section - Arizona-Nevada Academy of Science - April 16, 1988, University of Arizona, Tucson, Arizona
A preliminary survey of several urban lakes in the Phoenix metropolitan area was undertaken to assess the degree of accumulation of priority pollutant metals and petroleum -based hydrocarbons in these impoundments. Three sediment samples were collected from each lake along a transect (from a probable point of stormwater addition to the opposite shore), and were composited on an equal weight basis prior to analysis. Total petroleum hydrocarbon concentrations ranged from 30 to 8000 mg /kg dry weight. The concentration ranges (mg /kg dry weight) of total metals were: arsenic 7-26, copper 25-2800, chromium 14-55, nickel 5-40, lead < 1-138, selenium < 0.5-1.1, and zinc 33-239. Silver and cadmium were undetectable (< 5.0 and < 0.5 mg /kg, respectively). Factors that may be associated with the magnitude of accumulation in urban lakes include lake age, primary source of influent, reception of stormwater runoff, mechanical aeration of the water, and direct chemical addition.

Full text
Abstract:
The Gulf of Mexico (GoMx) is among the most productive regions for offshore oil and natural gas recovery. In 2010, the Deepwater Horizon (DWH) drilling rig exploded, burned for three days, sank, and released over 4 million barrels of oil in the subsequent 84 days before it was capped. Some oil was buoyant enough to float to the ocean surface, where some was removed via a myriad techniques. Importantly, a plume of oil remained suspended in the water column at approximately 1,100 m water depth, where it drove a marine snow event, and deposited large quantities of oil on the seafloor. The northern GoMx seafloor is complex and dynamic. Submarine canyons, mounds, channels, and salt domes dominate the seafloor along the continental slope surrounding the DWH well. Using high-resolution bathymetric data, variables derived to characterize the seafloor (water depth, distance, slope, and aspect), and spatial relationships between seafloor stations and the DWH well, relationships between concentrations, fluxes and inventories of polycyclic aromatic hydrocarbons, and other seafloor variables were hypothesized to be statistically significantly related. The most significant seafloor characteristic to predict distributions was water depth, followed by distance, relative aspect, and slope.

Full text
Abstract:
Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently. However, during biological and chemical degradation of PAHs other toxic compounds may be formed. If these transformation products are sufficiently persistent they could potentially accumulate during remedial processes. In the work underlying this thesis the degradation and transformation of PAHs were studied in three remedial processes: viz. a pilot-scale bioslurry reactor, microcosms with wood-rotting fungi and lab-scale treatments with Fenton's reagent. A group of transformation products referred to as oxygenated-PAHs (oxy-PAHs) was found to be particularly important, as these compounds are toxic and were shown to be relatively persistent in the environment. The oxy- PAHs were, for instance, found at significant concentrations in the gasworks soil used in most of the studies. This soil was highly weathered and had therefore been depleted of the more readily degradable compounds. In addition, experiments in which earthworms were exposed to the gasworks soil showed that the oxy-PAHs were more easily taken up in living organisms than PAHs. To facilitate the studies, new extraction and fractionation methods were developed. For instance, pressurized liquid extraction (PLE) was investigated for its reliability and efficiency to extract PAHs and oxy-PAHs from soil. Furthermore, a selective PLE-method was developed that can simultaneously extract and separate the PAHs and oxy-PAHs into two different fractions. This was accomplished by adding a chromatographic material (silica or Florisil) to the extraction cell. Under certain conditions all three remedial processes resulted in increasing amounts of oxy- PAHs in the soil. For example, 1-acenaphthenone and 4-oxapyrene-5-one accumulated in the bioslurry reactor. Similarly, in the soil inoculated with a white-rot fungus 9-fluorenone, benzo[a]anthracene-7,12-dione, 4-hydroxy-9-fluorenone and 4-oxapyrene-5-one accumulated. Finally, in an ethanol-Fenton treatment the concentration of some PAH-quinones increased in the soil. The results show that it might be necessary to monitor oxy-PAHs as well as PAHs during the remediation of PAH-contaminated sites. Otherwise, the soil may be considered detoxified too early in the process. In the long term it would be desirable to include analyses with sufficient marker compounds to follow the possible production and elimination of the oxy-PAHs. However, until such compounds can be identified it is suggested that contaminated soil should be screened for oxy-PAHs in general. The selective PLE-method presented in this thesis could be a useful tool for this.

Abstract:
The widely accepted theory of the organic origin of oil and gas accumulations is practically not used to select promising areas and places for exploratory drilling. This makes us pay close attention to the alternative mineral concept of the genesis of these minerals. The purpose of the book is to show how ideas about the deep inorganic origin of accumulations of oil and hydrocarbon gas developed from antiquity to modern times, before the creation of modern mineral theory. The importance of mineral theory for forecasting large oil and gas fields, as well as for optimizing oil and gas geoecology is shown. For a wide range of readers interested in the origin of oil and gas fields, as well as the history of the development of this field of knowledge.
