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 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 textDuring the Late Ordovician, a continental-scale ice sheet extended over the north Gondwana platform. The resulting glaciogenic sedimentary successions constitute the most important petroleum reservoirs of the Saharan fields. This study was carried out from field data and satellite imagery of the plateau du Tissaghert in southwest Libya. The studied sedimentary succession shows three depositional systems. These systems correspond to a first Southern ice-marginal setting upstream, comprising a glacial basin with the associated glaciotectonic complex and a connected network of incised channels, which are developed during glacial advance and infilled during glacial retreat. This ice marginal system is connected downstream, to a second Northern proglacial fluvio-deltaic system that corresponds to a delta-plain setting including fluvioglacial channels and that evolves downstream into river-mouth and low-angle prograding delta front environments. The overall deltaic architecture builds up from repeated glacial outbursts, mainly during glacial advance and ice-front stabilization. A third postglacial transgressive tidal and wave-dominated system superimposes these two previous systems and depicts ice-front retreat and the subsequent global deglaciation. The two first glacially related systems represent the late part of a lowstand system tract, and the third system represents a subsequent transgressive system tract. They all characterize the signature of a glacial sequence consequently defined by a cycle of glacial advance and retreat. These results also allowed the creation of a 3D analog reservoir model of the Ordovician-Silurian petroleum system

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

Full textThe continental organic matter deposited in the deep basins is little described and represents a definite interest for the petroleum industry. Understanding the sedimentary processes that allow the deposit and preservation of this organic material of terrestrial origin in the deep basins is fundamental. During the Palaeogene, a period of glacial transition to icehouse, the Mackenzie Delta, located in the Arctic Basin, receives and maintains continental organic matter from the continent. What is the stratigraphic and climatic context that made possible the export of continental organic matter? Initially, the sedimentary study of the basin showed a mixed mixture dominated by the fluviatile process, with less influence of the process of storms and tides. This model of facies associated with the study of the logs of wells available in the zone made it possible to propose a model of electrical appliances of the wells of the basin and to characterize the sedimentary sequences of the delta to evolve over time and to demonstrate its migration to Beginning of the Paleogene in response to the establishment of the Brooks and Rocky Ranges. Despite the contradictory biostratigraphic constraints that had to be re-evaluated and poor quality seismic data and strongly impacted by the contemporary deformation of the Brooks chain, it is possible to propose a stratigraphic and sedimentological division along two land-sea transects. Paleogeographic series of the Mackenzie Delta. The sedimentary study of the basin showed the presence of influence of the tidal process in the internal zone of the Arctic Basin. The common presence of pollen from Avicenna and Nypa showed the existence of a mangrove well established in the Arctic domain during the Palaeogene with associated temperatures of at least 18-20 ° C. The deposits of organic matter are in the Almost all of continental origin of the Mackenzie Delta. This organic matter is of two types: (1) deposits of coal deposited during the period when the mangrove develops and (2) deposits formed by association of plant debris and amorphous organic matter and deposited under reducing conditions under the water interface -sediment. These deposits of organic matter are the most important at the end of the prograding sequences in the facies of the deltaic plain. A positive correlation was found between the increase in OCD and the increase in detrital inputs in the delta, as well as between deposits of coal and illite. On the other hand, no correlation between the second type (organic debris + MO amoprhe) of organic matter and the clayey cortege could not be demonstrated. From the comparison of organic matter deposits in the Mackenzie Delta and Lomonosov Ridge, the sedimentation rate and anteriority appear to be key parameters in sedimentation conditions and especially in the preservation of organic matter according to l Oxygenation of the medium. Moreover, Lomonosov's Ride presents itself as a guest in a home where it is permitted to remain in semi-emerged position during the Paleogene

Full textThe Paris basin is currently considered as a typical example of intracratonic basin (sag) affected by long term thermal subsidence. The Cenozoic is a period a low subsidence (less than 300m thick) and correspond to the end of the Paris basin sedimentation. Moreover, it is a period of strong deformation of the European plate related to Africa Europe convergence and North Atlantic opening, well known through numerous grabens inversions in northern and eastern Europe. While hiatus have been highlighted within Paris Basin sedimentation, cenozoic deformations of this thicker crust basin still poorly known. This thesis aims at recompose high resolution temporal and spatial evolution of 3D sedimentary geometries and palaeogeographies from Thanetian to Lower Oligocene. This work is firstly based on available and newly acquired biostratigraphic data. Facies sedimentolgy and well data correlations based on sequence stratigraphy principles allowed to recompose the basin evolution at 1Ma timescale. 2 orders of sequences were identified. Third order sequences (1My duration) seems to be controlled by climate-eustasy. Five main (2nd order) sequences bounded by unconformities and/or palaeogeographic reorganization are highlighted : (1) Maastrichtian-Danian ; (2) Thanetian-Ypresian ; (3) Lutetian-Bartonian ; (4) Bartonian-top Priabonian et (5) Top Priabonian-Chattian. Sequences 1 to 4 correspond to basin scale flexure which control their architecture. Following emersion during the main flexural phases, flooding start with relatively steep depositional profiles. As flexure progressively relax, flatter depositional profiles take place together with overall transgression. This work yield high resolution constraints for the understanding and thermomechanical modelling of intraplate deformations various lenght of flexures form 150 to 300km and more are identified and traduces different thickness of deformed lithosphere. From Thanetian to Bartonian, successives E-W oriented flexures take place which ages are congruent with the main phases of Iberia-Eurasia convergence. A short term deformation in basal Ypresian is attributed to the onset of North Atlantic opening. Finally major basin-scale reorientation during Priabonian could be linked to the onset of Apulia- Eurasia continental collision

Full textThe diversity of facies and depositional environments of the Oxfordian of Lorraine allowed to propose a new lithostratigraphic framework. The survey of field and subsurface data using facies sedimentolgy and sequential stratigraphy allowed to describe 13 transgressive-regressive depositional cycles between the Mariae zone and the Planula zone. The depositional systems evolved from a marl-limestone ramp deepening southward, to a reefal and/or oolitic carbonate platform and finally to a marl-limestone ramp deepening northward. Amplifications of high frequency relative sea level falls appear in transgressive context and coi͏̈ncide with climatic changes. Thirteen oxfordian depositional cycles are inserted in 6 medium frequency transgressive-regressive cycles and, in 5 cases, floodings are contemporaneous with tectonic events. Those 6 cycles are inserted in a low frequency regressive transgressive cycle and accommodation minimum appear in the upper part of the Middle Oxfordian

Full textGeothermal spring carbonate (GSC) corresponds to a complex carbonate system formed around carbonate-rich springs fed by rising groundwaters along permeable fault zones. Their development is mainly controlled by the nature of springwaters emerging above water table. Therefore carbonate deposition is, in this setting, intimately related to complex interactions between hydrological, tectonic and structural processes occurring prior to water emergence. Moreover, carbonate sedimentation from springwater results from sedimentary processes controlled by complex interactions between hydrological, chemical characteristics and biological activity. Such processes are sensitive to slight environmental variations and thus lead to a large spectrum of lithofacies and ecosystems.The aim of this study is to improve knowledge and fundamental concepts regarding development of geothermal spring carbonates. For that purpose, lithofacies investigation, from microfabrics at micro-scale to 3-dimensional configuration at field-scale, is considered as an essential tool. Such investigations had been carried out in sites where Quaternary and actively forming GSCs were abundant (e.g. Rapolano region, Italy, Denizli Basin, Turkey and Yellowstone National Park, Wyoming, USA)

Full textWe develop here a methodology to integrate the mineralogical record into a high resolution sequence stratigraphic framework realized in the Early Eocene Graus-Tremp-Ainsa Basin. Coupling stratigraphic with geochemical and mineralogical approaches allows us to unravel the effects of tectonics, climate, eustasy and diagenesis on basin architecture and mineralogy. An automated computed mineralogy is derived from whole-rock geochemical data, and calibrated against direct mineral quantifications (petrography, DRX, Qemscan, microprobe). It provides a basinscale view of mineral distribution, irrespective of the lithology. Diagenetic overprint and hydrodynamic sorting effects are evaluated first, then primary mineral distributions are reconstructed and ascribed to different types of sediment sources.We show that, at the million-year timescale, tectonics shape the architecture and the mineralogy of the deposits. Spatially distributed diagenesis and temporal and spatial changes in sediment sources reflect the competing effects of intrabasinal tectonics (local thrust displacements) versus basinscale flexural subsidence linked to the orogen uplift and loading. Tectonically-driven changes are also sensitive to higher frequency (100 ky) anomalic climatic events (PETM, ELMO, X-EVENT) leaving a mineralogical signal in clay fractions and environment deposits succession.The basinscale evolution displays two contrasting stages. During the Ilerdian to the lower Cuisian, a mixed carbonate ramp evolves to a set of deltaic fans of Northern (Pyrenean orogen) provenance delivering plutonic-dominated materials. Then, during the lower/mid Cuisian, they are overprinted by a large fluvial and deltaic system bringing recycled carbonates and siliciclastics sourced in the emerging eastern to southern sedimentary thrust sheets. Later on, the propagation of the Montsec thrust and its lateral ramp decouples the uplifted Graus-Tremp basin from the strongly subsiding Ainsa basin. These different subsidizing schemes are underlined diagenetic overprints diverge, with an extensive kaolinisation of the uppermost units in the Graus-Tremp Basin driven by meteoric fluid circulations, and a severe albitisation of sandstones in the Ainsa basin, coupled with the illitisation of smectites in the lutites and caused by deep basinal fluids

Full textHamakoussou and Mayo Oulo-Léré sedimentary basins are extension of the executive branch of East-West Yola Benue Trough, whose formation is related to the opening of the South Atlantic from the dislocation of Gondwana, in the Cameroonian territory. An age range of lower Cretaceous to Barremian-Hauterivian limit has been assigned based on biochronological studies. The sedimentary sequence in both basins is composed upward finnings fluivial to fluviolacustrine deposits. The deposits present an alternation of fine grained sandstone, siltstone and mudstone overlying coarse sandstone which is underlain by micro-conglomerate to conglomerate facies at the base.A magnetostratigraphic study has been carried out on a fine sediments in the upper part of each sections. 50 samples from about 69.03 m thickness, were collected from 11 sites at Djallou and 78 samples, about 511.03 m thickness, were collected from 20 sites at Ourokessoum localities in the Hamakoussou basin ; and 116 samples, about 478.19 m thickness, collected from 45 sites at Tchontchi locality in the Mayo Oulo-Lere basin.Specimens subjected to progressive alternating field and thermal demagnetization show that the sedimentary sequences have a primary magnetization. The directions of magnetization indicate a regional tectonic marked by a rotation and translation block. Rock magnetic investigations reveal the presence of both high and low coercivity minerals. A sequence of three polarities was determined along each section of the Hamakoussou basin: one reversal polarity and two normal polarities, whereas two polarities: (normal and a reversal) were determined along Mayo section in the Mayo Oulo-Lere basin The three polarities sequences from the two sections from Hamakoussou basin are correlated with M1 and M3 Chrons and suggest an age between 125 and 128, 11 My. While the two polarities sequences from the Mayo Oulo-Lere basin are correlated with M1 Chron, and suggest an age between 125 and 127.61 My. The sedimentation rates of Hamakoussou basin deposits vary between 5.5 cm/kyr and 40.88 cm/kyr and 38.26 cm/kyr in the section of Mayo Oulo-Lere basin

Full textThis transdisciplinary study including sedimentology, sequence stratigraphy, chemostratigraphy, and organic and inorganic geochemistry examines the Middle-Upper Jurassic carbonates series located in the southwestern Gissar range. These carbonates, also known as the Kugitang series, represent the most complete outcrop of the northern margin of the Amu-Darya Basin, a gas-producing province of Central Asia. Carbonate production begins in the late Early Callovian during a regional slowing of the tectonic subsidence, coeval with a climate warming. A major change in the carbonate production and platform configuration is recorded at the end of the Callovian: (i) a carbonate ramp with a well-contrasted proximal-distal gradient develops during the Lower to Middle or Upper Callovian. It is overlain by (ii) a vast low energy lagoon dominated by peritidal facies, probably protected by large reefs, during the Lower and Middle Oxfordian. The stratigraphic surface separating the two depositional sequences is associated with a hiatus (Upper Callovian-Lower Oxfordian) and interpreted as a regional exposure surface recording a sea-level drop caused by tectonics and/or climate. During the Middle Oxfordian, one or several intrashelf basins develop southwestwards of the studied carbonate platform. Laminated and nodular carbonates rich in organic matter predominate in these basins. They are interpreted to have formed through the mineralization of microbial mats colonizing the stratified, slightly hypersaline, anoxic to dysoxic basin floor. Large scale reefs may have favored the isolation of these basins. These deposits record the initiation of the tectonic isolation of the Amu Darya Basin, which culminates with the progradation of a large-scale sabkha and the deposition of a thick anhydrite and salt series. The comparison of stratigraphic series highlights common events in several basins of the northern Tethyan margin, but also with the Arabian Plate: initiation of the carbonate platform, carbon isotope excursions, age and depositional conditions of organic-matter rich rocks, etc. The petrography and geochemistry of carbonates reveal a complex diagenetic history. Some facies are strongly controlled by the sedimentary fabric. The diagenetic succession is tentatively linked with the stratigraphy and the subsidence history. Following deposition, the Kugitang series was buried at more than 2 km. Some cements are interpreted to have formed through the circulation of hot fluids in the rocks during the mesogenesis and possibly due to thermochemical sulfate reduction, especially in the Callovian Sequence. Finally, the high-resolution stratigraphy established in this study is used to help improving the prediction of carbonate reservoirs in the subsurface Amu Darya Basin

Full textDuring the opening of the Neotethys Ocean north of the Ghadames and Jeffara basin, an extensional phase created subsidence. It resulted in the deposition of the first syn-rift strata aged Middle to Upper Permian (El Watiah formation) and Lower to Middle Triassic (Bir el Jaja, Ouled Chebbi and Ras Hamia / Kirchaou formations). This study provides details of the stratigraphic and sequential architecture of triassic siliciclastic series and the upper clastic part of the El Watiah formation. 221 wells and 18 sedimentological field sections (outcrops from south Tunisia) have been correlated across the entire Ghadames basin and Jeffara. An organization in 11 sequences has been highlighted. 28 isochores and paleogeographic maps have been drawn. In terms of tectonostratigraphy, a major thickening of sequences has been confirmed toward the North of Jeffara, resulting from a very strong and differential subsidence. Low and subtle differential subsidence has been demonstrated in the southern part of the basin. In addition, a new sedimentological interpretation of the TAGI formation (lateral equivalent of the ladinian Ras Hamia formation) has been considered in the El Borma area

Full textThis manuscript provides the first exhaustive sedimentological study of the Dur At Talah escarpment (≈120 m high and ≈150 km length). This latter is exposed in the Abu Tumayam Trough, in the southern Sirt Basin (Libya). The Dur At Talah Formation forms a 2nd order regressive sequence, from shallow marine to fluviatile deposits, dated as upper Eocene. This exceptional outcrop allows an extensive and detailed sedimentological analysis (lithofaciès, ichnofaciès, geometries and sequence stratigraphy) leading to a multi-scale characterization of nearshore to paralic environments dominated by tidal dynamic. Among outstanding results, two sedimentary processes have been recognized and characterized: the progradation is expressed by large-scale clinoform structures and the lateral accretion is characterized by inclined heterolithic stratifications (IHS). Several sedimentary bodies are, thus, unequivocally distinguishable such as heterolithic mouth-bars and tidal channel point-bars. Thorough analysis of these sedimentary bodies allows to define diagnostic criteria to recognize them. They can be replaced in a consistent stratigraphic framework explaining their architecture and their vertical evolution in order to be used as reservoir analog
