Abstract:
An evidence-based annotated checklist of gobiid species (Teleostei: Gobiidae) inhabiting the South Caspian Sea and its catchment area (i.e., the South Caspian Sea sub-basin) is compiled. The South Caspian Sea sub-basin gobiofauna currently comprises 38 confirmed species in 11 genera (i.e., 88.4% of the Caspian gobiofauna); the most diverse genus is Benthophilus (16 species, 42.1%), followed by Ponticola (seven species, 18.4%), and Neogobius (four species, 10.5%). Ten species (26.3%) are endemic to the South Caspian Sea sub-basin, another 21 species (55.3%) are endemic in the Caspian Sea basin as a whole, six (15.8%) are native to the Ponto-Caspian region, and one species (2.6%) is exotic. According to the current IUCN Red List, 24 species (64.9%) are listed as being of “Least Concern”, eight species (21.6%) are “Data Deficient”, and five species (13.5%) as “Not Evaluated”. Similar numbers of species are confirmed to inhabit the South Caspian Sea sub-basin waters of the three countries that border it: Iran harbors 25 species (nine genera), Azerbaijan has 28 species (10 genera), and Turkmenistan has 26 species (10 genera). The greatest known diversity of Benthophilus in South Caspian waters occurs in Azerbaijan and Turkmenistan (11 species each), whereas Iranian waters harbor seven species. In comparison, Iran, with six out of eight species (75%), has the greatest diversity of Ponticola known from the Caspian Sea basin. Species richness and endemism of the Caspian Sea gobiid-fauna varies considerably with latitude: the North, Middle and South sub-basins respectively harbor 21, 31, and 37 native species, of which 0, 3, and 10 species are endemic in that sub-basin alone. The high species diversity and endemism of Gobiidae in the South Caspian Sea sub-basin may have resulted from: (i) greater ecological diversity compared to the northern Caspian Sea marine areas (e.g., water depths) that may have led to differential niche adaptation and adaptive radiation in the Benthophilus-Anatirostrum species flock, (ii) lower historical extinction rate compared to Caspian higher latitudes, which had greater exposure to the Pleistocene’s extreme climatic changes, (iii) geological history of freshwater habitats in the South Caspian Sea sub-basin that set the speciation and evolutionary stage for the genus Ponticola during these Pleistocene climatic oscillations, (iv) presently less limiting conditions compared to the North Caspian Sea, i.e., higher present winter minimum of water temperature and higher salinity, and (v) Iranian freshwater abundance, variability and habitat diversity. Contemporary gobiid diversity and endemism in the Caspian Sea basin suggests two higher-priority conservation areas: (i) freshwater habitats of the South Caspian Sea region in Iran and Azerbaijan, and (ii) shallow coastal and deep waters of the South and Middle Caspian Sea sub-basins. An identification key is provided for the updated gobiid species from the South Caspian Sea sub-basin.

Abstract:
The South Caspian Basin, the northern Alborz Mountains, the Gorgan plain and the Moghan plain constitute the northernmost and youngest petroleum system in Iran. This region was part of the Paratethys realm from Oligocene to Pliocene time. The Oligocene – Miocene Maikop/Diatom Total Petroleum System of the South Caspian Basin produces major volumes of hydrocarbons in Azerbaijan and Turkmenistan, and the Iranian sector of the basin has consequently undergone exploration due to its generally similar geology. The 20 km thick, dominantly Cenozoic sedimentary cover in the basin is reduced to less than 3 km in the northern foothills of the Alborz Mountains, and scattered surface oil seepages in the latter region are believed to be generated by Cretaceous and Miocene source rocks. In the Moghan plain to the southwest of the South Caspian Basin, anticlinal folds of Oligo‐Miocene Zivar Formation sandstones may be prospective for hydrocarbon exploration. Mud volcanoes in the Gorgan plain and in adjacent offshore regions at the SE margin of the South Caspian Basin are associated with hydrocarbon seepages, and appear to be sourced by Cretaceous and Cenozoic shales and mudstones. Major structural features in the southern part of the South Caspian Basin include Cenozoic mud diapirs, folds and gravity structures.

Abstract:
Ejection of breccia from mud volcanoes for the onshore and offshore South Caspian Basin provides hazards for rigs, pipeline, and subsea completion equipment. Here we investigate the lateral ranges of ejected rock fragments for aeolian and submarine conditions. In addition, the consequences are considered of emission from a raised or depressed crater, with or without a surrounding crater wall. Also investigated is aeolian transport to an ocean surface, and subsea motion thereafter. Rough rules of thumb for aeolian hazards from breccia would indicate that seconds to tens of seconds after breccia emission is the onset time of hazard, with hazard distances typically of order a few hundred meters, but occasionally reaching about a kilometer or so for fairly large (5 kg) rocks emitted at high (∼500 m/s) speeds, with impact speeds of order 10–100 m/s. Submarine hazards yield 0.1-4 m/s impact speeds on the ocean floor for water depths in excess of about 2 m. For shallower water depths the aeolian impact speed is a good approximation. The hazard potential to equipment from breccia is one of concern, with a worst case distance estimate of about 1 km from the ejection point.

Abstract:
Heating hazards caused by mud volcano flame eruptions are assessed for the South Caspian Basin. In general, it is found that winds of more than about 50 km/hr will cause serious heating hazard problems when directed partially downward onto flame columns of greater than a few hundred meters in length. Hazard distances from emergence points of flame columns at which the surface temperature is less than 60°C, stinging hot against human flesh, are typically in the 5–15 km range. Low angle emergent flames are more easily bent to lick the emergent surface than are high angle flames, providing a higher hazard closer to the flame emergence point but a lower hazard further away. Both field examples and numerical models are used to illustrate the heating hazards to rigs, pipelines, and infrastructure equipment. The hazard to oil exploration and production conditions in the South Caspian is then clear.

Abstract:
The paper presents the generalized materials on the current state of fisheries in the Northern part of the Caspian Sea (southern region of the Volga-Caspian fisheries basin). It is shown that catches in the North-Western and Tersk-Caspian subdistricts varied in the opposite way: an increase in production in one subdistrict was accompanied by a decrease in the other. The decreasing or increasing catches is due to semi-anadromous (roach, brim, zander, carp) and freshwaterfish species (cat-fish, pike-perch, small size ordinary fish). There have been found the significant relationships between the size of catches in the North-Western and Tersk-Caspian subdistricts with the annual runoff and the volume of spring flooding of the Volga river, which allows to conclude that fish resources are redistributed between these regions depending on the natural conditions of a particular year. In order to more fully develop the fish resources of the southern region of the Volga-Caspian fisheries basin, it is recommended to abandon the division of quotas into parts for the North-Western and Tersk-Caspian subdistricts and to allow the fishing organizations to work at the expense of the total allowable catch

Abstract:
Understanding the nature of mud volcanism, mechanisms of formation, types of eruptions and their relationship to the hydrocarbon systems provides important information about subsurface conditions and geological processes within the South Caspian Basin. A 2D seismic grid in southeastern offshore Azerbaijan is used to define the areal distribution of mud volcanoes and to make a classification of the mud volcanoes based on characteristic seismic features. As a result detailed database for each determined mud volcano is constructed. Analysis of different parameters from this database shows that there is a high concentration of mud volcanoes at the southern part of the study area. It is coincides with the distribution of the subsurface structures within the basin. Mud volcanoes with low relief (several tens of meters) are mainly concentrated in the northeast. Conversely, mud volcanoes with large vertical relief (greater than 200 m) are clustered in the southwest part of the basin. Mud volcano development in the South Caspian Basin is generally linked to faults, which in some instances are detached at the basement level. By using interpreted seismic surfaces it is possible to determine relative time of mud flows from the mud volcanoes. Timing of mud flows reveals to the actual activity of the mud volcanoes and it gives valuable information about possible mechanism of mud volcanism within the South Caspian Basin. Previous studies of the onshore mud volcanoes in Azerbaijan and the results from current work conclude that mud volcano formation within the South Caspian Basin is mainly controlled by tectonic forces and overpressured sediments. Mud volcano activity is not always related to the Maykop organic reach shale succession. It can occur at shallow depths by pressure breakthrough from any stratigraphic zone.

Abstract:
The main objectives of this project are to (a) understand the relationship between climate, topography and the tectonics in the Greater Caucasus belt, (b) construct regional geological cross-sections showing major stratigraphic sequences and structures along the belt using the focal mechanisms of the earthquakes events, (c) evaluate the evolution and development of a single fold structure (Yasamal anticline) and (d) investigate strain accommodation mechanisms using 3D Move to unfold the Yasamal structure. Topographic variations were investigated to understand the interplay between topography, climate and the tectonics of the Greater Caucasus range and compare the findings with other active and inactive belts (Pyrenees, Northern Tibetan Plateau and Himalayas). There is a correlation between elevation changes and climate along the Greater Caucasus belt, where the gradual reduction of the mean altitude, has a close relationship with a wetter climate, and the sharper altitude decrease with a drier climate. And the elevation changes are strongly correlated with the Moho depths underneath the region. The relief along the belt is extremely high, with a strong correlation between the high relief and the large thrusts in the region. And the relief of the eastern part is slightly low compared with the western part of the belt, even though the eastern part is more active than the western part. The structural study undertaken at regional scale for the Caucasus belt and the western side of the South Caspian Basin gave insights on the style of deformation in the basin and the evolution of the Greater Caucasus belt and the preferred distribution, geometry and formation mechanism of the structural elements. The regional cross-sections along the Greater Caucasus were constructed and constrained by using focal mechanisms show that the belt is deformed by active thrust faults that dip inwards from the margins of the range where the northern thrusts are dipping south, and the southern thrusts are dipping to the north, these results have contrary to some previous models that emphasise only south-directed thrusting. The spatial arrangement, geometry and temporal evolution of spectacular kilometre-amplitude fold structures actively forming in Cenozoic sediments on the uplifted western margin of the South Caspian Basin are described and strain accommodation mechanisms established using 3D Move to unfold the Yasamal structure enabled a reconstruction of pre-folding templates and predictively model the fold-related deformation at small-scale. The 3D model of the Yasamal anticline shows that the anticline hinge has about 30° south-directed plunging. The area was characterized by a low rate of sedimentation and high rate of uplift in the Upper Pliocene. The minor structures (accommodating the overall strain in the anticline) are developed throughout the entire anticline. Compressional strain is present at the anticline hinge line, and the extensional strain dominates the anticline limbs. Suggesting potential extensional structures development in the anticline flanks, which correspond with the field observations in the Yasamal valley confirming that; the small normal faults are concentrated within the anticline flanks, and the contractional deformation bands along the hinge area of the anticline.

Abstract:
This thesis uses a combination of industrially acquired seismic reflection data, well data, topographic data and satellite imagery to investigate the structure, evolution and geophysical expression of extrusive constructions found within large (-500 m diameter) mud volcano systems from the South Caspian Basin. The principal aim is to gain a better understanding the structural architecture of mud volcano systems and the ways in which they are constructed. To this end this thesis includes three core research chapters which present investigations into the internal structure and eruptive history of a large mud volcano system, the geophysical response of seismic data to gassy seabed conditions and the structure and formation of mud volcanic subsidence craters. In the first core chapter the edifice of the giant C'hirag mud volcano system was investigated using three-dimensional (3D) seismic data. Internally, this feature consists of a number of discrete seismic facies units interpreted to represent either wedge-shaped units of erupted mud volcanic sediment or sheet-like units of non-eruptive sediment. Unit stacking patterns indicate the importance of pulsed mud volcanic activity as a control on the internal architecture of large mud volcano edifices and suggest it to be an important mechanism of basinal sediment and fluid expulsion. Analysis of the geometrical relationships of the internal sediment units to an underlying collapse caldera allows for a reconstruction of the system's history of collapse. Together, the details of internal unit type, stacking and relative edifice collapse timing constitute a detailed reconstruction of the volcano system's eruptive history and a record of the structural evolution of a large focussed fluid flow system. At the seabed a number of volcano systems within the South Caspian Sea study area were found to be imaged by areas of phase-reversed seabed reflection in seismic data. These "seabed phase reversals" are useful for better delimiting and understanding the structure of mud volcano source points and the extent of recent eruptive deposits. At one example kilometre-scale lobate mudflows are seen emerging from two seabed mud pool (salses) emphasizing the importance of both features in shaping the volcano's seabed morphology. Testing the hypothesis that seabed phase reversals are the result of gas within the seabed sediment took the form of a one-dimensional geophysical model of the study area seabed constructed using data from a borehole together with other published data. The results revealed that a phase reversal of the seabed reflection is a geophysical possibility under conditions typical of gassy seabed sediment. There is therefore a high likelihood that seabed phase reversals are the result of gas within seabed sediment. It is therefore suggested that seabed phase reversals can be used alongside other acoustic phenomena that indicate the presence of gas in a sedimentary section. In the final core chapter circular craters found at the upper terminations of onshore and offshore mud volcano systems are investigated. Using field maps. seismic lines, topographic data and satellite images it has been possible to describe these craters in detail for the first time and compile a generalized model for their structure. This includes a crater rim, an inward dipping crater margin fault, a moat and raised crater pedestal of freshly extruded mud volcanic sediment. The characteristic "moat and pedestal" morphology features at most of the craters featured here as well as at a number of others from elsewhere. Whilst the precise mechanism of crater formation is unclear it is strongly suspected that they form as a result of subsurface evacuation and collapse. They are thus similar to other sedimentary and igneous collapse features for which they may be useful analogues.

Abstract:
The Pleistocene – Present-day sedimentary succession of the South Caspian Basin was deposited syntectonically alongside growing anticlines in an under-filled, rapidly subsiding basin. The combination of ample sediment supply from surrounding mountain belts, fast sedimentation rates (variously estimated at between 0.4 and 1.7 m/kyr) and high accommodation space has resulted in an exceptionally thick succession (up to 3000 m) which documents structural growth and regional tectonics at a high temporal resolution. The succession additionally records the palaeo-water level history of the Caspian Sea —an internally drained lake— which has fluctuated at much higher magnitudes and frequencies throughout the study interval than along comparable marine settings. The Pleistocene – Present-day Caspian stratigraphy therefore represents an ideal geological dataset with which to study depositional processes along syntectonic fold ‘growth strata’ and to investigate the relative impacts of tectonics and climate change on syntectonic sedimentation. This thesis presents three studies which describe South Caspian Basin fold growth strata at a variety of scales using offshore seismic data from the north-eastern portion basin and field data from western Azerbaijan. The studies examine; [1] the vertical spacing and regionally lateral synchronicity of angular unconformities within late Pliocene – Present-day growth strata; [2] Pleistocene basin margin syntectonic sedimentology, and: [3] the process of large scale slope failure from submarine landslide deposits along folds located in the basin interior. The results of these studies add to the scientific understanding of the regional geology and of tectono- sedimentary processes in general. However the main finding —recurrent in all three studies— is the presence of repetitive sedimentary patterns and correlations. These are suggested to represent orbital Milankovic cycles of 40,000 years (obliquity) and 100,000 years (eccentricity). Orbitally driven climate change appears to have been a major control on South Caspian fold growth strata architecture and sedimentary processes within anticline mini- basins. Fold growth effects are also observed but these are relatively subdued as tectonic uplift was outpaced by high sedimentation rates.

Abstract:
Interpretation of 900 km of a closely spaced grid of high-resolution seismic profiles over the northwestern margin of South Caspian Basin (SCB) allows recognition and study of six late Pleistocene - Holocene depositional sequences. Sequence stratigraphy analysis of sedimentary strata from 117,000 years B.P. to present led to the identification of a highstand systems tract, two transgressive systems tracts and six lowstand systems tracts. Each systems tract is characterized by specific seismic facies. Diverse depositional processes on the northwestern margin of the SCB are suggested by the thirteen seismic facies patterns recognized in the study area. Two distinct progradational complexes were interpreted within Sequence III and Sequences IV and V in the northeastern and northwestern parts of the study area, respectively. Stratigraphic interpretation of the sequences provided important information on parameters that control depositional architectures, such as lake level fluctuations, tectonic dynamics, and sediment supply. High sedimentation rates combined with a series of high-frequency and high-amplitude lake-level fluctuations, abrupt changes at the shelf edge, abnormally high formation pressure, and high tectonic activity during Quaternary time resulted in the development of a variety of complex geologic drilling hazards. I distinguished three types of hazards as a result of this study: mud volcanoes, sediment instability, and shallow gas. The 2D high-resolution seismic dataset from the northwestern margin of the SCB allowed more detailed seismic sequence stratigraphic analysis in the study area than has previously been attempted. In particular, it has a clear application in deciphering sediment supply and relative lake level changes as well as tectonic relationship of the northwestern shelf margin of the SCB. Results of this work led us towards better understanding of recent depositional history, improved our knowledge of the nature of the basin tectonics, climate history and styles of and controls on sedimentation processes within a sequence stratigraphic framework during the late Pleistocene-Holocene time.

Abstract:
The Azeri, Chirag and Gunashli (ACG) oilfield is located in the offshore Azerbaijan sector of the south Caspian Basin. This dissertation focuses on the Azeri Field which has over 8 billion barrels of oil in place. The major reservoir interval is the Pliocene Pereriv Suite, which is characterized by laterally continuous layers of variable net-to-gross (NTG) deposited in a fluvial-deltaic environment. The Azeri Field is being developed by both down-dip water injection and up-dip gas injection. This dissertation uses high-resolution models, derived from outcrop analogue and subsurface data, in conjunction with experimental design techniques, to rank the impact of different geological heterogeneities on recovery by both displacement mechanisms. Firstly, the impact of reservoir-unit scale heterogeneities on water and gas injection is assessed using a simplified fluids PVT description. At this level, the principal controls on oil recovery are the factors that affect sandbody connectivity and sweep efficiency. Secondly, the impact of reservoir- and genetic-unit scale heterogeneities on gas injection in high NTG intervals is assessed. The genetic-unit scale heterogeneities that control the approach to vertical equilibrium (VE) are found to be the principal controls on recovery. Their impact is large when gravity forces dominate the mobility unstable displacement, but decreases with increasing production rate as viscous forces dominate and the displacement moves out of VE. The presence of laterally extensive shales is also important, because they change the geometry of the reservoir layering and yields higher recovery than equivalent homogeneous models. The same rank order of key heterogeneities is obtained for simulations with simplified and a more realistic PVT description. Finally, the results are applied to develop a methodology to identifY the upper and lower boundaries on predicted recovery using a simple analytic approach that incorporates some geological heterogeneity.

Abstract:
The study examines sediments of the Productive Series from the western South Caspian Basin. The main goal of this work is to reconstract provenance of the sediments and its relation to the climatic variability during the deposition of the Productive Series. The Productive Series is divided into a lower and upper division. The Russian Platform was the main sediment source area for the Lower Division. Three different sediment source areas were determined for the Upper Division: the Russian Platform was sediment source area for the Absheron Peninsula; the Greater Caucasus was the main sediment source area for the South Absheron Offshore Zone and the Lesser Caucasus was the main sediment source area for the Baku Archipelago. The sediments of the Lower Division have variable smectite and illite concentrations which indicate climate change between humid and arid conditions in the Russian Platform. The Upper Division of the Productive Series from the Absheron Peninsula is characterised by high amounts of illite. It suggests physical weathering under arid climatic condition on the Russian Platform at the time of deposition. Variation of the smectite and illite assemblages of the Upper Division from the South Absheron Offshore Zone probably indicate that the climate alternated between humid and arid conditions in the Greater Caucasus. The low amount of the TOC ratios in the Productive Series are associated with arid climatic condition in the Russian Platform and the Greater Caucasus. The much higher TOC/TN ratios (>35) indicate that sediments of the Productive Series were impacted by oil. However the low TOC/TN ratios (<12) in some intervals of the Productive Series suggest an aquatic source for an organic matter.

Abstract:
Mud volcanoes constitute an important component of petroliferous basins and their understanding is essential for successful exploration and development of hydrocarbon fields. They occur in both extensional and compressive tectonic settings, along with passive and active continental margins. Although extensive research exists on the geochemistry, geomorphology and stratigraphic evolution of these localized fluid flow structures, little is known about their geomechanical characteristics. This research investigates the geomechanics of mud volcanoes from the South Caspian Basin and West Nile Delta. This is achieved by establishing a workflow for geomechanical assessment of mud volcanoes using a P-wave velocity dataset from across the mud volcano within the offshore South Caspian Basin. This objective is developed further with the availability of seismic and wellbore data from around the Giza mud volcano, offshore West Nile Delta. Preliminary results of this study from the South Caspian Basin enable confidence in estimating the realistic magnitudes of elastic rock properties, stresses and fluid pressures from empirical and analytical correlations. Moreover, analysis of the variations in fluid pressures allow the fluid flow models around the mud volcano to be constrained and their gradients provide preliminary estimates of the drilling window. Structural and stratigraphic analysis around the Giza mud volcano offers insight into the formation of the mud volcano during the Quaternary and how the fault networks on the hanging wall of the arcuate tectonic fault have acted as conduits for primarily the pre-Pliocene fluids exploiting the areas of weakness along the hanging wall of the fault by entraining the Pliocene sediments. Fluid pressure evaluation reveals small overpressures caused by disequilibrium compaction. Further analysis offers insight into the critical fluid pressures that control fault movement, the stresses responsible for rock deformation around the wellbore and the width of the drilling window constrained by the fracturing of the strata. Analysis presented here provides details on the geomechanical significance of mud volcano environments, with implications for engineering practices. Overall, findings contribute to a systematic understanding of mud volcano settings not only from a field exploration and development point of view, but also at a wider scale for basin analysis and relatively small scale for play analysis.

Abstract:
Ce manuscrit étudie le rôle du gaz dans les processus de génération de boue en se concentrant sur un jeu de donnée riche et pluridisciplinaire du volcan de boue actif d’Absheron (VBA) dans le Bassin sud caspien. L’étude est divisée en trois parties principales : la définition de la source de la boue ; l’analyse du comportement hydromécanique des sédiments compactes après exsolution de gaz ; la modélisation numérique de la formation du VBA.J’ai d’abord identifie la Formation du Surakhany Anhydritique (ASF) comme la source du VBA : les données sismiques montrent une géométrie de zone de déplétion et la boue émise présente une minéralogie et un Age (Pliocène) compatibles avec ceux de l’ASF. L’ASF se compose d’une interstratification de bancs évaporitiques et de sédiments argileux à faible densité, en surpression et sous compactes. La source de la boue semble localisée au niveau d’un intervalle présentant des propriétés intrinsèques favorables à la remobilisation et à la convergence d’une accumulation de surpression et de gaz.J’ai ensuite teste l’impact de l’exsolution de gaz sur les propriétés hydrodynamiques des sédiments compactes grâce à un nouveau système de consolidation. Les résultats montrent que les sédiments sont endommagés par l’exsolution et qu’ils ne retrouvent pas complètement leurs propriétés initiales après la recompaction. Si l’exsolution de gaz mène à un degré de saturation en gaz supérieur à 38%, j’ai observé un comportement critique que j’interprète comme le résultat de la génération de boue.Enfin, j’ai intégré tous ces résultats dans des modèles numériques simples afin de confronter les hypothèses sur la formation du VBA aux conditions géologiques. Un modèle de diffusion 2D confirme que l’association d’une transmission latérale de pression et d’une migration verticale de gaz le long des failles mènent à la génération de boue. Des équations de mécanique des fluides montrent que la boue peut alors remonter jusqu’au fond marin par inversion de densité, mais la propagation de fractures et la prise en compte d’une viscosité dynamique pourraient participer et accélérer le processus de remobilisation. Mon travail de modélisation a permis de tester plusieurs hypothèses et dépasser d’un modèle de formation du VBA purement conceptuel a un modèle semi-quantitatif.Cette étude identifie les paramètres clés contrôlant la formation d’un volcan de boue, qui seraient communs à la plupart de ces structures. Une méthode de modélisation a été développée et elle peut être adaptée et améliorée afin de simuler la formation de volcans de boue dans des contextes géologiques différents
This manuscript assesses the role of gas in the mud generation processes by focusing on a dense and multidisciplinary dataset of the active Absheron mud volcano (AMV), South Caspian Basin. The study is divided in three main parts: definition of the mud source; analysis of the hydro-mechanical behavior of compacted sediments after gas exsolution; numerical modeling of the AMV formation.First, I identified the source of the AMV as being the Anhydritic Surakhany Fm. (ASF): seismic geomorphology evidences a depletion zone below the AMV and samples from surface mudflows indicate a Pliocene age and the same mineralogy as the ASF. The ASF is composed of interstratified anhydritic beds and low-density overpressured and undercompacted clay-rich layers. The mud source seems located in an interval presenting intrinsic favorable properties to remobilization and at the convergence of overpressure build-up and gas accumulation.I then tested the impact of gas exsolution on the hydro-mechanical properties of compacted sediments through a novel consolidation apparatus. Results show that sediments are damaged by gas exsolution and do not recover completely after reloading. Gas exsolution leading to a degree of gas saturation higher than 38% generates a critical behavior interpreted as the result of mud generation.I finally integrated multidisciplinary data and results in simple numerical models to confront the hypothesis on the AMV formation with the geological conditions. A 2D diffusion model confirms that the association of lateral pressure transmission and vertical gas migration along faults leads to mud generation. Fluid mechanics equations show that mud is then able to rise up to the seafloor by density-inversion. Accounting for fracture propagation and dynamic viscosity may improve and accelerate the mud remobilization process. I tested several working hypotheses through this modeling and went from a purely conceptual formation model for the AMV to a semi-quantitative one.This study identified key parameters for mud volcano formation that are believed to be common to most of these structures and allowed developing a modeling approach that may be adapted and improved to describe mud volcanoes formation in other geological contexts

Abstract:
Multiple oil discoveries reveal the global scale and economic importance of a distinctive reservoir type composed of possible microbial lacustrine carbonates like the Lower Cretaceous pre-salt reservoirs in deepwater offshore Brazil and Angola. Marine microbialite reservoirs are also important in the Neoproterozoic to lowest Cambrian starta of the South Oman Salt Basin as well as large Paleozoic deposits including those in the Caspian Basin of Kazakhstan (e.g., Tengiz field), and the Cedar Creek Anticline fields and Ordovician Red River “B” horizontal play of the Williston Basin in Montana and North Dakota, respectively. Evaluation of the various microbial fabrics and facies, associated petrophysical properties, diagenesis, and bounding surfaces are critical to understanding these reservoirs. Utah contains unique analogs of microbial hydrocarbon reservoirs in the modern Great Salt Lake and the lacustrine Tertiary (Eocene) Green River Formation (cores and outcrop) within the Uinta Basin of northeastern Utah. Comparable characteristics of both lake environments include shallowwater ramp margins that are susceptible to rapid widespread shoreline changes, as well as compatible water chemistry and temperature ranges that were ideal for microbial growth and formation/deposition of associated carbonate grains. Thus, microbialites in Great Salt Lake and from the Green River Formation exhibit similarities in terms of the variety of microbial textures and fabrics. In addition, Utah has numerous examples of marine microbial carbonates and associated facies that are present in subsurface analog oil field cores.
