Full textThe Late Ordovician glaciation is considered as an outstanding event of Earth history. Preservation of Ordovician glacial deposits is exceptional into the Murzuq Basin (Libya) and the aim of this PhD thesis is to study this succession. This work is principally based on field work study in the Ghat-Tikiumit area (west rim of the basin) associated with remote sensing analysis and petroleum investigation methods (stratigraphical modelling and interpretation of 3D seismic surveys). Results consist in relationships between ice-sheet dynamic, stratigraphical architecture and depositional system reconstructions at various space and time scales. Thus, two major glacial cycles are recognized into the Libyan glacial succession. Both terminate by a complete ice-sheet retreat and associated postglacial transgression at basin scale. Each cycle comprise several glacial phases (ice-sheet advance then retreat). Ice retreat is followed by the deposition of a glacial depositional sequence. During ice-sheet advances, the study area is repeatedly covered by ice streams. The final deglaciation sequence creates landward stepwise imbricate proglacial fan-deltas and associated ice fronts. Final postglacial transgression is driven by strong remnant topography and is responsible for the localisation of the Ordovician reservoir rocks and Silurian "hot-shale". Results consist in, into the Murzuq Basin, sequence stratigraphy interpretation of the glacial succession, eustatic evolution as well as ice-sheet and sedimentary reconstruction through the different glacial cycles and phases

Full textThis study explores the sequence stratigraphic evolution of the Early to late Miocene Upper Cibulakan Formation in the North West Java Basin, Indonesia. The primary objectives are to reconstruct depositional environments, understand regional stratigraphic evolution, and forecast the physical and dynamic parameters controlling the distribution of potential reservoir stratigraphic forward modeling. The study employs a model-independent sequence stratigraphic approach, integrating sedimentological, biostratigraphic, well log, and seismic data.The methodology involves two main phases: the development of a sequence stratigraphic framework and stratigraphic forward modeling. The sequence stratigraphic framework is built by identifying sequence boundaries, maximum flooding surfaces, and transgressive surfaces. Biostratigraphic data, electrofacies determination, well-to-well correlation, and seismic interpretation contribute to this framework. Seismic facies identification further enhances understanding, linking seismic reflector geometries to depositional processes. The second phase employs stratigraphic forward modeling using the Dionisosflow. This numerical technique simulates basin infill over geological time scales, considering factors like tectonic deformation, subsidence, sea level fluctuations, and sediment flux. Calibration involves structural evolution, sediment input settings, and transport parameters. The models are classified based on depositional facies, and uncertainty and sensitivity analyses assess the impact of various parameters.Results showcase the integration of biostratigraphic, well, and seismic data, providing insights into the geological evolution of the North West Java Basin. Twelve third-order sequences, organized into three second-order sequences, were interpreted within the Upper Cibulakan Formation. Four facies association has been revealed, based on gamma-ray log values; and nine seismic facies were identified, characterized by unique geometry and reflector configuration as well as stratal termination. The Aquitanian - early Burdigalian marked the dominance of northern and northeastern deltas, while the Burdigalian - early Langhian saw further deltaic progradation southward. The Langhian - Serravallian was characterized by a transgression, leading to the abandonment of the delta and the emergence of marine tidal bars. The Tortonian witnessed basin subsidence, reduced sediment supply, and the formation of isolated carbonate reefs.The Stratigraphic Forward Modeling simulation, involving a timeframe from 22.2 to 8.4 Ma, was constructed. The accommodation of sediment is governed by eustasy and tectonics; the sediment transport parameters, are carefully selected through systematic analysis and sensitivity testing, ensuring accuracy of the models in replicating observed thickness and lithological variations. The analysis of potential reservoir distribution shows that the prospective reservoir zones tend to follow a north-south orientation, influenced by rift direction that led to different sediment compaction and delta geometry, which influence accommodation space. Based on uncertainty and sensitivity analysis, sediment supply appears to be the most influential parameter compared to other parameters in the modeling

Full textForearc basins are under explored areas by academic or industrials research. They are not considered as potential area by oil industry because only one giant oil field belongs to this type of basin. Such a oil field is located in the northern Peruvian forearc system: The Talara basin. Our research focuses on the Tumbes forearc basin located north of the oil bearing Talara basin. The aim of this work is to provided for oil industry skills about the tectonic style and the stratigraphic architecture of this basin in order to decipher its petroleum potential using a multisource approach of surface and subsurface data (seismic lines, well-logs). On a tectonic view point, we demonstrate that the basin structure is not a pull-apart one but an accretionary prism built by deep-seated north-verging thrusts reworked by shallow gravitational normal faults. A tectonic model is developed corresponding to the northwestward propagation since Eocene times, of thrust-related culminations bounded by south-east facing normal faults. This tectonic model suggests that anticline traps, which have never been explored, should become a new target for future exploration. Sequence stratigraphy allows us deciphering the stratigraphic architecture of the Tumbes basin. In the Oligocene-Miocene succession, 15 base level cycles have been identified onshore and have been correlated using seismic data to the offshore portion of the basin. The Corvina gas field has been the depositional area of thick turbiditic body (channels and fans) which have been deposited during periods of forced and normal regressions. These good reservoirs rocks are interbedded with thin fines which have been deposited during transgressive periods. Such a stratigraphic architecture suggests a alternation of good to fair reservoir topped by transgressive seals, which may increase significantly the hydrocarbon resources of the Tumbes forearc basin

Full textAll stratigraphic models building and analysis are based on stratigraphic correlations of sedimentary units observed on wells or outcrops. However, the geologist building these stratigraphic correlations faces two main problems. First, the data available are few and sparse. Second, the sedimentary processes leading to the deposition of the units are numerous, interdependent and poorly known. So, the construction of a stratigraphic correlation model might be seen as an under-constrained problem with several possible solutions. The aim of this thesis is to create a numeric method to generate stochastic stratigraphic models that are locally constrained by observation data. Two steps are necessary: 1. The establishment of rules describing the spatial organization of sedimentary units observed on outcrops and wells. For these rules, two axis are explored: - The formulation in equations of rules defined in the sequence stratigraphy framework. These rules, presented qualitatively in the literature are translated in quantitative terms to evaluate the probability of two sedimentary units to be correlated. - The deduction of the probability of two sedimentary units to be correlated from stratigraphic models built from forward stratigraphic methods. 2. The development of an algorithm to build possible stochastic stratigraphic models from the rules cited above and observation data

Full textThis pioneering work, focuses on the study of the stratigraphic architecture of the Cuanza Basin, from a combined multi-scale approach crossing the geomorphology, seismic interpretation and sedimentologicalfacies from Oligocene interval to Present. The objective is to identify the age, the partitioning of facies, the environments of deposition of the coastal zone in order to date and characterize the vertical movements in relation to the salt creep (gravitational tectonic) and the general uplift of the margin related to the deformation of the lithosphere. Detailed analysis of the outcrops of the coastal zone allowed in a complementary manner specify the conditions of drainage of the paleo-Cuanza putting thus in evidence the identification of a deltaic prism type bird's foot in Pliocene which prograde on a coastal aeolian system. In addition, over to the basin, up to Bom Jesus, a shoal area led to the establishment of a Gilbert delta powered by a possible proto-Cuanza, in conjunction with the mixed platform of lower Miocene. Most off the shelf, in the area of Cabo de Sao Braz to Barra do Cuanza, a detailed analysis of the stratigraphic architecture of the cliffs allowed characterize in a viewpoint facies and depositional processes in a succession of channel-levee systems in compensation, showing locally early sandy injection processes related to the instability of the channel borders. These systems Oligocene to Pliocene are tightly controlled by the growth of diapirs (Cabo Ledo) and and sometimes they are fed by fluvial deposits, dismantling folds diapirs and contributions from mixed platform. In Sangano the turbidite channel banks contain the bioclastic sands with bioturbations type Skolithos and Ophiomorpha which indicate gravitational instability of the shelf that edge the subsidence incisions with a potential for colonization of the sandy bottom by Fauns "turbiportées". Going up to the north we pass gradually to slope facies highlighted by levels of black-shale that marks the window of planktonic productivity. These facies are overlain by marl with intervals of tempestites, characteristics of the offshore transition. Finally, to the South of Miradouro da Lua, we were able to put in evidence in upper Miocene contouritesfacies that climbs the slope following a series of grooves erosion. These facies are truncated by sandy deposits bioturbed typical of shoreface. From Cabo de Sao Braz until Luanda, sometimes is possible to obsreve a temporal and paleoenvironmental succession which reinforces the model of differential uplift or tilting of the series toward to the North. From South to the North, is observed an evolution of interdipiricturbiditic deposits of Oligocene to lower Miocene in the area of Cabo do Sao Braz / Cabo Ledo to deltaic facies of the paleo-Cuanza - Pliocene fluvial braid-delta of Pleistocene in Miradouro da Lua

Full textThe Vaca Muerta Formation is the principal source rock in the Neuquén Basin (Argentina). It constitutes also the major unconventional play in Argentina. Therefore, the Vaca Muerta formation stirs up large interest in the oil industry to understand the architecture and the organic matter distribution of this reservoir. Our study proposes an integrated approach, using sedimentology, stratigraphy, mineralogy and geochemistry in order to understand the depositional system and the paleoenvironmental conditions. The ultimate goal of this work is to clarify the stratigraphic relationship between organic-rich level and the basin filling. In the eastern part of the Neuquén basin, the study of 3D seismic allowed us to identify a wave-dominated depositional system and assess the role of the local tectonic and the eustatic control through seismic geometry. We carried out extensive field investigation, including logs and sampling, first in the Picún Leufú Anticline (southern part of the basin) and second, on several areas along a N-S trend over 500 km distance. This study allowed to define two major sectors which evolve differently. The first one corresponds to the central and southern part of the basin (from Picún Leufú Anticline to Chos Malal). There, an evolution from a siliciclastic shelf to a mixed ramp setting is observed during the Tithonian-Valanginian interval. Sediments were redistributed along the shoreface by longshore currents and further transported by storm and gravitary currents basinward. The second sector corresponds to Malargüe area (North area). It displays a perennial carbonate ramp during the Tithonian-Valanginian interval. Sequence stratigraphy analysis of all areas shows an homogeneous signal with five transgressive-regressive sequences in the basin. The geochemistry and clay mineralogy indicate the climate role in the evolution of the sedimentary environments. Geochemistry displays a “normal marine” environment with oxic waters and short-lived episodes of euxinia that coincides with the organic-rich levels. Lastly, the integrated approach, connecting stratigraphy end geochemistry shows four to five organic-rich intervals that coincide with the transgressive systems tract

Full textThe Lekhwair/Habshan/Salil (or LHS) system is a carbonate succession that prograded across the eastern part of the Arabian plate from Berriasian to early Bareremian. The three ormations that compose this system respectively correspond to the inner platform (Lekhwair Fm. ) platform margin (Habshan Fm. ) and slope to basin facies associations (Salil Fm. ). In Interior Oman, this system shows a conspicuous prograding character with well-expressed clinoforms (Berriasian to Valanginian). The formations imaged on seismic crop out toward the North in the Oman Mountains (upper Valanginian to lower Barremian). This aim of this study is to precise the stratigraphic and geometric organisation of the LHS system at the scale of the sedimentary basin and the depositional sequences, but also to improve the understanding and the prediction of the carbonate reservoir into these prograding systems. The study went through a combination of an interpretation of prograding geometries by seismic stratigraphy and a sedimentologic and stratigraphic outcrop analysis in the Jebel Akhdar (Oman Mountains). This analysis of this system from the Berriasian to the early Barremian allows the interpretation of the relative sea level variations of the Cretaceous and the tectonic episodes that affected the arab plate in this time

Full textThe Barremian–Aptian stratigraphic interval occupies a key position in the evolution of the carbonate systems during the Cretaceous related to: climatic changes (warm and arid during Barremian, then warmer and more humid during Aptian) and the tectonic changes (increase in volcanism linked to a higher speed of the sea-floor spreading); changes of the ecosystems and ecological community replacements at the same time in the benthic and pelagic domains; first occurrences of deposits enriched in organic matter on a worldwide scale (called "Oceanic Anoxic Events": OAE1a and OAE1b); the geometrical complexity of the carbonate platforms. The topic of this thesis is to understand the logic in the ecological and geometrical organization of the Barremian-Aptian carbonate platforms and to evaluate the relative influence of the various factors that control the sedimentation (tectonics, eustatism, oceanography and climate). Although many studies exist concerning this time interval, a synthetic model is still not available. For this reason, this work is supported by an IFP project related to the global study of the lower cretaceous platforms around the peri tethyan domain. This requires the development of a multidisciplinary approach which exceeds the local scale and which takes into account the elements provided by the paleontology, the sedimentology, the stratigraphy and the geochemistry. Good quality outcrops which are partially already studied, are analyzed around Tethyan realm: in Spain, in France, in Switzerland and in Oman. There seems to exist a good adequacy between the various Barremian-Aptian sedimentary systems in these geographic sectors. The aim is to provide a geometrical, sedimentological and ecological reference model calibrated in a precise time framework

Full textDuring the Early Cretaceous epoch, intensive magmatic activity due to the dislocation of the super-continent Pangaea, highly influenced global environmental conditions, which were characterized by a warm and generally humic climate. In this context, carbonate platforms were important in tropical and subtropical shallow-water regions, and especially during the late Barremian and early Aptian, platform carbonates of so-called Urgonian affinity are widespread. In southeastern France, the Urgonian platform was part of the northern Tethyan margin and bordered the Vocontian and the Bedoulian basins. The goal of this thesis was the systematic study of the Urgonian Formation in this region, and in order to achieve this goal, a biostratigraphic chart and a facies model were developed. The faunistic assemblages, the facies succession, the field observations and the study of geochemical signals lead to a sequential subdivision of the Urgonian series along 54 sections and wells allocated in five different regions in southeastern France (Gard, Ardèche, Vercors, Vaucluse and Provence). Correlations from this stratigraphic study highlight important variations in thickness and depositional environments of the Urgonian series. These variations are explained by relative movements induced by syn-sedimentary faults, which divided the Urgonian platforms into blocks. On the southern border of the Vocontian basin, these faults, oriented N30° and N110°, delineate six tilted blocks. At the top of the upper Barremian carbonates, subsidence of the two southern blocks accelerated leading to the opening of the Bedoulian basin. The reconstruction of the sequence-stratigraphic and paleoenvironmental evolution of the Urgonian platforms was then tested by the construction of a 3D numerical model of the Urgonian formation of southeastern France. Firstly, its consistency with the data collected during this study, and secondly, its geometrical coherence validate the proposed theory. Urgonian analogs exist all over the world and particularly in Middle East where they constitute important oil reservoirs. The exact reconstruction of the major factors, which influenced the architecture of these formations, will allow for a better exploitation of these energy resources

Full textThe Algerian margin is a complex domain, limited to the south by the Maghrebian internal zones (AlKaPeCa) that overthrust the external Tellian zones southward. The offshore part of this system constitutes a back-arc basin, where a mio-pliocene sedimentary series were deposited over a substratum of laterally variable origin and nature. The goal of the present work consisted in analyzing and modelling the petroleum system at work and calculating hydrocarbon volumes. Before proceeding to different numerical basin, stratigraphic and thermal modelling, a conceptual geological model is required and was performed based on field geological studies and stratigraphic and structural interpretations of the seismic profiles. The extension of the continental crust beyond the foot of the margin, allows determining a chronostratigraphic model by extrapolation of the outcroping oligo-miocene formations onshore to the acoustic pre-messinian units defined in the offshore basin. Besides, a tectonic analysis in both onshore and offshore domains gave rise to three main steps of evolution: (1) syn-rift phase where the basin was opened by transtension since Late Oligocene- Aquitanian, (2) post-rift phase in which intra-arc basins were developed, AlKaPeCa and Africa docked and magmatism activity took place, (3) inversion phase where the margin became active mainly since Quaternary times. After defining the different petroleum system elements taking into account variable uncertainties, the 2D/3D petroleum system model depicts possibilities of oil and gas accumulations mainly close to the margin, between 20 to 65 km from the coastline to the north with a maximum range of 70 km in the Bejaia Gulf

Full textThe objective of the present work is to characterize sediment supply dynamics within the Plio-Pleistocene Corinth Rift using an integrated approach based on field observations and analyses, experimental modeling and numerical modeling. Detailed sedimentological, structural and biostratigraphical studies on the southern coast of the rift provide a tectono-stratigraphic model within a well-constrained climatic and eustatic setting. Stratigraphic simulations (DIONISOS) are used to validate this model, to quantify the sediment supply and to discuss the relative role of four controlling factors on stratigraphic architecture (sediment flux, water flux, subsidence, eustasy). Finally, a geomorphological experimental approach has been developed to study the relative role of factors (rainfall, uplift rate. . . . . ) that control sediment supply and their record within the sedimentary signal

Full textThe main objective of this study is to better understand and to quantify experimentally the main parameters that control the geomorphological and stratigraphic evolution of the Cenozoic sedimentary succession of the northeast Santos basin, Brazil, in the last 49.5 my. For this purpose, a variety of combining methologies were used, such as: seismic analysis of a dataset composed of different resolution levels (~7-8 s and ~400 ms penetration), chronostratigraphic and lithological data from 19 exploratory wells and stratigraphic modeling. Seismic analysis and stratigraphic modelling led to the identification of 9 main stratigraphic sequences that could be grouped into 3 megasequences (Megasequences A, B and C): (i) Megasequence A is characterized by deltaic features developed into a ramp feature located between Guanabara Bay and Cabo Frio. The formation of this delta resulted in a sedimentary overcharge that induced the basinward salt migration. The sedimentary input that feeds this delta was interpreted as related to an ancient Paraíba do Sul River that diversion to the Campos basin at the end of the megasequence development, resulting in a dramatically reduce the sedimentary influxes into Santos basin; (ii) Megasequence B is characterized by the retrogradational trend of sedimentary systems that offset offlap break of surfaces developed at 30 and 21 Ma about 78 km landward. This megasequence is also characterized by the beginning of conturites deposition related to the changes of oceanic circulation due to the opening of Drake and Tasmanian passages; (iii) Megasequence C is characterized by progradational systems that resulted in the coastline shift about 70 km oceanwards, in the last 11.5 my. The dominant progradational trend of this sequence is interpreted as a response of the increase in the sedimentary influx rate intensified by the spectral characteristics and amplitude of the glacial-induced eustatic signal that characterizes the Quaternary period

Full textCarbonate platforms are characterized by complex sedimentary and stratigraphic architectures that can be expressed at length scale exceeding single outcrops. This work focuses on the Barremian (Lower Cretaceous) deposits of the Gresse-en-Vercors cliff (southeastern France) that provide a seismic-scale slice though a platform margin - analogous to Middle East reservoirs - ideal to study large scale carbonate platform developments in continuous. The cliffs are 500 m high and extend for 25 km along depositional dip, straddling the transition from shallow water platform to deeper basin. New biostratigraphical data shows that the Vercors platform is mainly Lower Barremian. Four stratigraphic sequences were defined, with two complete platform stages, separated by three drowning events.New high-resolution numerical data (LIDAR point-set and high-resolution georeferenced photos) obtained by helicopter survey, allowed the realization of a 3D high-resolution DEM over the entire outcrops. Integrating the stratigraphic observations and the DEM in gOcad result in a continuous 3D stratigraphic architecture and facies model of the carbonate outcrop that can be used for stratigraphic and sedimentological interpretations. The resulting geological model demonstrates that outcrop numerical data and 3D geological modeling are pertinent tools for improving carbonate outcrop characterization and conceptual models of carbonate platform systems. It allows to establish subtle sedimentary profiles and high resolution facies mosaic along seismic scale platform trend. This approach is particularly critical for the 3D characterization of clinoforms and stratigraphic system tracts in non-cylindrical carbonate systems: for example, apparent low stand wedge or distal onlapping lobes in 2D are in reality prograding high stand systems in 3D

Full textStratigraphic modeling aims at rebuilding the history of the sedimentary basins by simulating the processes of erosion, transport and deposit of sediments using physical models. The objective is to determine the location of the bedrocks likely to contain the organic matter, the location of the porous rocks that could trap the hydrocarbons during their migration and the location of the impermeable rocks likely to seal the reservoir. The model considered within this thesis is based on a multi-lithological diffusive transport model and applies to large scales of time and space. Due to the complexity of the phenomena and scales considered, none of the model parameters is directly measurable. Therefore it is essential to inverse them. The standard approach, which consists in inversing all the parameters by minimizing a cost function using a gradient method, proved very sensitive to the choice of the parameterization, to the weights given to the various terms of the cost function (bearing on data of very diverse nature) and to the numerical noise. These observations led us to give up this method and to carry out the inversion step by step by decoupling the parameters. This decoupling is not obtained by fixing the parameters but by making several assumptions on the model resulting in a range of reduced but relevant models. In this thesis, we show how these models enable us to inverse all the parameters in a robust and interactive way

Ce motif de dépôt, fondamentalement horizontal, est récurrent et sert à la hiérarchisation des unités sismiques en grandes séquences de dépôt. Il correspond à l'enregistrement d'un cycle glacioeustatique de 100 000 ans (interglaciaire-glaciaire) : le prisme PI correspond aux dépôts prodeltaïques de « haut à moyen niveau marin » ; le prisme PII, aux dépôts littoraux de plus bas niveau du maximum glaciaire du cycle. Cette interprétation rejoint celle proposée par Aloïsi en 1986. Au total, cinq séquences correspondant aux cinq derniers cycles glacio-eustatiques sont donc enregistrées sur la plate-forme occidentale du Golfe du Lion. La base des séries étudiées remonte à 540 000 ans (stade isotopique 12). Les cycles très courts (20 000 ans ou moins) ne sont pas clairement exprimés dans les géométries de dépôt. Les conditions hydrodynamiques exercent un contrôle sur les géométries des séquences de dépôts qui peut brouiller ou effacer l'empreinte des cycles climatiques dans les séquences sédimentaires. Les canyons de l'Aude et de l'Hérault sont globalement inactifs pendant les hauts niveaux marins. Pendant les bas niveaux, leur fonctionnement est variable (transport, érosion et dépôt).
Les simulations stratigraphiques et la restitution des couples de prismes observés et exceptionnellement bien préservés dans cette zone du Golfe du Lion donnent une signification géologique et valident la transformation « simple » des courbes isotopiques O18/O16 en courbes eustatiques. Cette étude donne aussi la première quantification du taux de subsidence moyenne (totale) de la plate-forme du Golfe du Lion pendant le Pléistocène supérieur à moyen (540 ka). La subsidence prend la forme d'un basculement vers le large qui atteint 250 m/Ma à 70 km de la côte actuelle (en bordure de plate-forme). On a calculé, à partir des géométries visibles sur les profils sismiques pétroliers, un taux de subsidence identique sur l'ensemble du Plioquaternaire ; le taux de subsidence est donc constant depuis 5,3 Ma, il ne crée pas de séquence mais permet la préservation, l'empilement et la reconnaissance des séquences glacioeustatiques successives.

Full textA zonation based on planctonic foraminifers has been established in the Paleocene basin of Chiapas. Eight zones were recognized : 4 in Danian, 2 in Selandian and 2 in Thanetian. This zonation allows a good correlation with the european zonation and with the major events described in the chart of the European basins published by Hardenbold et al. (19981). We recognized two major regressions: the first one, at the Danian/Selandian boundary (boundary of Acarinina uncinata/Morozovelia angulata zones) and the second in the Thanetian, at the boundary of Luterbacheria pseudomenardii /Morozovella velascoensis zones. There are also two important transgressions: the first one in the Selandian (Igorina albeari zone) and the second, in the Thanetian (Luterbacheria pseudomenardii zone). The Paleocene basin of Chiapas is tectonically controlled by major EW strike-slip faults. The Tenejapa fault has probably a strong influence on the creation of Danian platform margin. Intense reworkings at the Danian/Selandian boundary and at the top of Luterbacheria pseudomenardii zone should be linked to fault activities

Full textThe study of the Urgonian sediments of Organyà Basin has permitted to characterise the sedimentary sequences deposited in this basin. Detailed sedimentary and facies studies allow us to propose a microfacies depositional model used for a good knowledge of the vertical evolution of sedimentary environment. An exhaustive inventory of microfauna and microflora has been presented. Owning the micropaleontological and sedimentologieal data 6 sedimentary sequences have identified. In comparison with the foraminifera distribution well known in other alpine basins, the OR-0 sequence is dated from Valanginian age, the OR-1, OR-2 and OR-3 sequences as Upper Barremian and the last ones (OR-4 and OR-5 sequences) as Lower Aptian. Four main types of sediments has been identified: - silty limestone with terrigenous influence in the OR-0 sequence; - shelf-margin and inner platform limestone in the OR-1 sequence and OR-2 sequence respectively; - charophytes limestone at the base of OR-3 and OR-4 sequences and, - planctonik foraminifera and rich anoxie lime stone in the OR-4 and OR-5 sequences. Sequence stratigraphy of this region is now detailed, due to quantification of the microfauna, specially useful to distinguish the different systems tracts. Two anoxic episodes are observed at the top of the Urgonian sediments; they are correlated with one of the global Cretaceous Oceanic Anoxie Events (OAE 1a)

Full textThe sedimentology and tectonics and their relationship of the Paleozoic series that fill the Ghadames basin and its northern extension consisting of the Jefarah basin in Libya and Tunisia was studied. These formations belong to the Gondwana cycle and are typically interpreted as being deposited in a cratonic basin truncated by the Hercynian unconformity. This study is based on wells. The stratigraphic correlation between the wells is based on the definition of second order cycles. This allowed to produce isopach maps of facies distributions and to reconstruct the paleogeography of the different stratigraphic units. These data allow to address the nature of the deformation and also clarifies the behavior of active high regional areas during the Palaeozoic. The Paleozoic succession in the Ghadames and Jefarah basins can be divided in to five first order sequences, bounded by major tectonic unconformities with sequence duration of 40 - 70 Ma. Within these five sequences eighteen second order sequences (10 - 40 Ma) were differentiated, describing Sequence Boundaries (SB), Maximum Flooding Surfaces (MFS) and sedimentological characteristics. Twenty six wells with its geological well reports and well logs have been used in the study area, i.e. the Ghadames and Jefarah basins (Libya) illustrate how reservoir properties changes laterally and vertically through time (from a proximal to a distal sitting). Two softwares were used, JLog (version 4) petrophysical software for reservoir property analysis and PETREL (Schlumberger software 2014 version) for constructing stratigraphic correlation models. The Paleozoic reservoirs in the study area are spread over a large range of siliciclastic reservoirs with the prospective section extending from Cambrian to Permian. Hydrocarbons within the Ghadames and Jefarah basins originated from two major source rocks: i.e. the Lower Silurian Tanezoft Formation and Middle-Upper Devonian Aouinat Ounine Formation. The nine main Paleozoic reservoirs are respectively the Hassaouna, Haouaz and Memouniat Formations (Lower Paleozoic), Acacus, Tadrart, Ouan Kaza and Tahara Formations (Middle Paleozoic) and M’rar and Asadjefar Formations (Upper Paleozoic). Six stratigraphic cross sections through the area have been reconstructed to illustrate the vertical and lateral reservoir extensions. The dataset demonstrates that the Paleozoic reservoir properties are influenced by both, depositional facies and position within the paleogeographical setting (from proximal to distal part)

Full textAn original method for the generation of 3D facies model has been implemented. It simultaneously accounts for well and seismic data, sedimentological rules describing the spatial distribution of rock types, or sequence stratigraphy principles. Different probability cubes are computed by integrating one or several pieces of information controlling the facies occurrence: the relationship binding the facies to the paleolandscape, the lateral transitions of facies, the stratigraphic control of shoreline migration, the sediment volume partitioning or the diagenesis potential. The generated probability cubes can then be combined, considering the redundancy of the data they express. The suggested methodology provides therefore an extensible framework for the integration and the combination of data from diverse origins and types, sometimes redundant and whose weight in the final model can be balanced according to the data uncertainty

Full textThe Tertiary paleogeographic evolution of the Black Sea, within the paratethys realm, was characterised by several periodic isolation episodes. The eutatic responses of the Black Sea to these de-connexions, and particularly those related to the Mediterranean Messinian crisis, are still not clearly established. The high resolution seismic stratigraphy study we present is based on interpretation of multichanel HR seismic data correlated with drillings recovered on the occidental Black Sea margin. Our investigations were concentrated on the identification of erosional surfaces, interpreted as markers of eustatic falls, linked to the basin isolation phases. On the Romano-Ukrainian shelf, the seismic profiles display six major discontinuities regarded as Tertiary erosional surfaces : (1) the surfaces underlined at the base of the Eocene (E), at the base of the Oligocene (O), in the Middle Miocene (M) and at the base of the Pontian (P); (2) and two intra-Pontian erosional unconformities (L. IPU and IPU). On the other hand, the Messinian erosional surface was clearly identified on the Bulgaro-Turckish margin. Recent correlation between the Paratethysian and Mediterranean stratigraphic scale suggest that the IPU surface recognised on the Romano-Ukrainian shelf is equivalent to the Messinian erosional surface. Among the five ante-Messinian erosional surfaces described, we interpret the M surface as the signature of a catastrophic sea level fall related to the Upper Burdigalian isolation phase. We propose that the four other surfaces correspond either to submarine erosion episodes, or to transgressive events. The discovery of the Messinian erosional surface in Black Sea constituting the major result of this study, enables to validate the assomption about the Messinian Dessiccation of the Black Sea [Hsü and Giovanoli, 1979]

Full textChalk is the characteristic deposit of Late Cretaceous Northern Europe. This specific sediment still relatively poorly understood. The aim of this study is to better constrain the sedimentology and stratigraphy of the Paris Basin Chalk. We propose a facies model of the chalk. . We combine this facies model with well log data to perform high resolution correlations. In doing so, we constrain the 3D geometry and paleogeography of the Paris Basin during Late Cretaceous and identify the majors controls (tectonics and eustasy) on chalk deposition. We demonstrate the onset of a broad N-S compression during Late Turonian, attributed to the onset of the alpine cycle. Finally, we highlight a strong oceanic circulation, associated with an upwelling dynamic in northern Europe. Through the comparison of Chalk world repartition with published upwelling numerical predictions, we propose that the occurence of this specific sediment is directly linked to Cretaceous paleooceanography
