Abstract:
AbstractA fluvial /wave-dominated delta was formed during late Pliocene times in southwestPeloponnesus, influenced by NNW—SSE and ENE—WSW trending faults. The depositional patternremained unchanged through early Pleistocene times, when the pre-existing active faults with WNW—ESE extension were combined with an eastward asymmetrical subsidence of the graben. Inthe deltaic environment, marshes, lakes and lagoons were created in the western parts, whereas largequantities of sediments were deposited in the central and eastern parts adjacent to basin marginsof steeper relief.This study combines grain size parameters, total organic matter, carbonate and clay mineralogyand structural analysis to: (a) determine the pattern of sedimentation in sub-environments and (b)create a fluvial/wave-type deltaic depositional model, and distinguish between delta-plain, delta-front and pro-delta environments. The Pliocene-Pleistocene, fluvial/wave-dominated delta model inthis study can be used to predict deltaic sedimentation in analogous basins.

Abstract:
ABSTRACT Quaternary sediments exposed along Pasley River consist of a lower marine deltaic sand overlain in succession by complexly interbedded tills and glaciomarine sediments (the lower glacigenic assemblage), by a mid-section fluvial gravel, by an upper marine deltaic sand, and by glaciomarine sediment and till (the upper glacigenic assemblage). The midsection fluvial gravels contain plant and insect fossils indicating a climate as warm as and perhaps warmer than present. The top of the gravel is more than 55 000 years old ; the unit is probably of Sangamonian age (>75 000 ka) and separates Wisconsinan from lllinoian glacial deposits. The deltaic sands that underlie both glacigenic assemblages indicate substantial crustal depression during glacial buildup episodes prior to arrival of ice at the site. This implies that the process of buildup was slow and involved glacier expansion into major marine basins. Glaciomarine beds of the lower glacigenic assemblage locally contain abundant detrital terrestrial organic material as well as marine molluscs. The terrestrial organic detritus, an unusual constituent of glaciomarine sediment, is thought to have been released into the sea from glacier ice. These terrestrial fossil asemblages exhibit compositional differences which vary with the sediment faciès and probably reflect taphonomic factors such as differential buoyancy of the fossils. The upper marine deltaic sands contain some "old " rebedded plant detritus and amber indicating a nearby source of Tertiary sediment, possibly equivalent in age to the Beaufort Formation. Other rebedded fossils from the upper deltaic unit may be the same age as the mid-section fluvial gravels.

Abstract:
AbstractAn integrated study of sedimentological, sequence-stratigraphic and palaeodispersal analysis was applied to the Upper-Permian clastic sedimentary succession in the Northern Sydney Basin, Australia. The succession is subdivided into fifteen facies and three facies associations. The facies associations are further subdivided into eight sub-facies associations. The sedimentary evolution involves progradation from delta-front to delta-plain to fluvial depositional environments, with a significant increase in sediment grain size across the unconformable contact that separates the deltaic from the overlying fluvial system. In contrast to the delta front that is wave/storm- and/or river-influenced, the delta plain is significantly affected by tides, with the impact of tidal currents decreasing up-sequence in the delta plain. The general lack of wave-influenced sedimentary structures suggests low wave energy in the delta plain. The abrupt termination of the tidal impact in the fluvial realm relates to the steep topographic gradients and high sediment supply, which accompanied the uplift of the New England Orogen. The sequence-stratigraphic framework includes highstand (deltaic forest and topset) and lowstand (fluvial topset) systems tracts, separated by a subaerial unconformity. In contrast to most of the mud-rich modern counterparts, this is an example of a sand-rich tidally influenced deltaic system, developed adjacent to the source region. This investigation presents a depositional model for tidal successions in regions of tectonic uplift and confinement.

Abstract:
AbstractAlluvial architecture has been subject of many studies because of the occurrence of natural resources in ancient fluvial successions. This paper provides an overview of the current state of research on alluvial architecture with special reference to Holocene fluvio-deltaic settings. Several examples from modern fluvio-deltaic areas, especially the Holocene Rhine-Meuse delta (the Netherlands) and the Lower Mississippi Valley (U.S.A.), are used to illustrate the architectural elements that can be distinguished in fluvial successions and to show the influence of the various controls on alluvial architecture (base level, climate, tectonism, aggradation, avulsion, and compaction). Avulsion is regarded as a principal process in the formation of fluvio-deltaic sequences, because it determines the location and number of active channels on the floodplain. The avulsion mechanism is still subject of debate, though. A brief description of the evolution of process-based alluvial-architecture models is given. These models simulate the proportion and distribution of coarse-grained channel belts in fine-grained overbank deposits. The major drawback of the present-day alluvial-architecture models is the lack of (three-dimensional) quantitative field data to test and validate them. The paper concludes with the suggestion to collect more architectural data from natural fluvial settings, to improve simulation of channel-belt geometry in alluvial-architecture models, and to implement new data and knowledge of fluvial processes into models.

Abstract:
Much of the world’s conventional oil and gas production comes from fluvial-deltaic reservoirs. The ability to accurately interpret the architectural elements comprising these systems greatly reduces the risk in exploration and development in these environments. We have evaluated methods for using spectral decomposition attributes to improve the visualization in fluvial-deltaic environments using data from the Middle Pennsylvanian age Red Fork Formation of Oklahoma. We determined how spectral phase and magnitude attributes can be effectively combined using an hue-saturation-value color map to produce images that have considerable interpretational value. Incorporating our methods in the interpretation process has the potential to improve the exploration and development in these systems.

Abstract:
Investigations of sedimentary sequences in a marginal part of Homelen Basin (M. Devonian, W Norway) have resulted in the interpretation of gradually established fluvial and fluviodeltaic subsystems adjacent to a major river system. A succession of 8 coarsening upward (CU) sequences (4.5---19 m thick) wad studied. Three sequence types are recognized: sequence type A, B and C. The lower part of all sequence types is composed of silty lacustrine flood basin deposits. The upper part of all sequence types is composed of sandy low sinuosity fluvial channel deposits. The middle part of the three sequence types is composed of sandy sheet splay deposits (sequence type A), crevasse splay deposits (sequence type B) and deltaic mouth bar deposits (sequence type C). The genesis og the different types of CU sequences is explained by repeated lateral establishments of fluvial and fluvio-deltaic subsystems adjacent to a major humid fan-like river system. The establishment of the subsystems occurred in four phases: I) Initial fine-grained overbank flows into flood badin lakes. II) Sheet splay flows and/or crevasse splay flows. III) Establishment of distributary channels and associated deltaic mouth bars. IV) Progradation of channel/mouth bar couplets and filling up of the flood basin lakes.

Abstract:
Quantitative and qualitative variations in microscopic plant organic matter assemblages and its preservation state in deltaic channel deposits of Mahanadi River was correlated with the depositional environment in the ecosystem in order to prepare a modern analogue for use in palaeoenvironment studies. For this, palynological and palynofacies study was carried out in 57 surface sediment samples from Birupa river System, Kathjodi-Debi River system and Kuakhai River System constituting Upper, Middle and Lower Deltaic part of Mahanadi river. Theapex of the delta shows dominance of Spirogyra algae indicating high nutrient, low energy shallow ecosystem during most of the year and recharged only during monsoons. The depositional environment is anoxic to dysoxic in the central and south-eastern part of the Middle Deltaic Plain (MDP) and Lower Deltaic Plain (LDP) indicated by high percentage of nearby palynomorphs, Particulate Organic Matter (POM) and algal or fungal spores. The northern part of the delta show high POM preservation only in the estuarine area in LDP but high Amorphous Organic Matter (MOA) in MDP. The sediment here is deposited under dysoxic to oxic fluvial conditions. Thus, the monsoon intensity, direction of fluvial discharge, and the landward extent of sea water incursion through river mouths inducing bottom water salinity play an important role in defining the magnitude of POM and its preservation in the shallow Mahanadi deltaic ecosystem.

Abstract:
Abstract Dune-scale cross-beds are a fundamental building block of fluvial-deltaic stratigraphy and have been recognized on Earth and other terrestrial planets. The architecture of these stratal elements reflects bed-form dynamics that are dependent on river hydrodynamic conditions, and previous work has documented a multitude of scaling relationships to describe the morphodynamic interactions between dunes and fluid flow. However, these relationships are predicated on normal flow conditions for river systems and thus may be unsuitable for application in fluvial-deltaic settings that are impacted by nonuniform flow. The ways in which dune dimensions vary systematically due to the influence of reach-averaged, nonuniform flow, and how such changes may be encoded in dune cross-strata, have not been investigated. Herein, we explored the influence of backwater flow on dune geometry in a large modern fluvial channel and its implications for interpretation of systematic variability in dune cross-strata in outcrop-scale stratigraphy. This was accomplished by analyzing high-resolution channel-bed topography data for the lowermost 410 km of the Mississippi River, which revealed that dune size increases to a maximum before decreasing toward the river outlet. This spatial variability coincides with enhanced channel-bed aggradation and decreasing dune celerity, which arise due to backwater hydrodynamics. An analytical model of bed-form stratification, identifying spatial variability of cross-set thickness, indicates a prominent downstream decrease over the backwater region. These findings can be used to inform studies of ancient fluvial-deltaic settings, by bolstering assessments of proximity to the marine terminus and associated spatially varying paleohydraulics.

Abstract:
Optimizing the extraction of oil and other hydrocarbon products from existing sites is important. One source of hydrocarbon products is reservoirs found within sedimentary rock formations. Understanding fluid behavior within such formations can be quite useful in optimizing oil production. Fluid behavior within sedimentary formations is influenced by the bedform structure and permeabilities within the formation. Thus, we are concerned with developing a physically and statistically valid method of characterizing sedimentary rock formations. The use of archetypal analysis to generate synthetic bedforms, as well as the use of Kriging to assign permeabilities within a bedform, was explored. With these tools, a characterization of a sedimentary rock formation can be created and fluid flow through the charactrerization examined. It appears that the bedform structure within a realization has a greater influence on fluid flow than any permeability structure created by utilizing Kriging.

Abstract:
Combined seismic and well interpretation methods can be used to elucidate detail of the subsurface architecture of fluvial and fluvio-deltaic deposits. Observations made from wireline and core logs, including facies and analysing the relative proportions of architectural elements and facies associations indicative of depositional sub-environments, can be used to interpret patterns of cyclicity, changes in local accommodation conditions, and periods of increased seasonal, tidal and marine influence. Horizon slices, taken from 3D seismic volumes aid in the visualisation of laterally discontinuous, often thinly-bedded, fluvial deposits. Seismic facies, when combined with core and wireline log facies, can be interpreted as a series of ‘seismic elements’. The relative proportions of seismic elements mapped out on horizon slices allows the interpretation of depositional environments and accommodation setting; allowing the distinction between fluvial and deltaic settings. A number of data conditioning and seismic interpretation techniques can be used to enhance the visualisation of channelized and non-channelized fluvio-deltaic deposits in the subsurface. Frequency decomposition (and the making of colour-blended volumes) allows the visualisation of the detail of channel belt deposits such as channel belt migration and lateral accretion deposits. Allogenic processes, particularly base-level (buttress) rise and fall have been shown to exert a control on the overall stacking pattern of the studied fluvio-deltaic deposits, whereas autogenic processes are interpreted as the major control on the local arrangement and architecture of channel belt and overbank deposits. The first study in this thesis uses the Upper Permian Rangal Coal Measures, a large-scale fluvial system, which accumulated in a foreland basin setting in the Bowen Basin, Queensland, Australia. The study investigates the architecture and connectivity of splay and distributary channels. The second study uses the Late Triassic Mungaroo Formation, a Mississippi-scale fluvio-deltaic system with a fluvially-dominated, tidally-influenced delta, which accumulated in the Northern Carnarvon Basin, Northwest Shelf, Australia. The study investigates different seismic interpretation techniques and investigates the relative control on fluvio-deltaic deposition of allogenic and autogenic processes.

Abstract:
The Pliocene-Recent Muda formation is essentially undeformed in the West Natuna Basin, and excellent resolution of this interval on three-dimensional seismic data in Belida Field allows detailed interpretation of component fluvial-deltaic systems. Detailed interpretation of seismic time slice and seismic sections along with seismic facies analysis, horizon mapping, and extraction of seismic attributes provide the basis to construct a sequence stratigraphic framework and determine patterns for sediment dispersal and accumulation. The Muda interval contains five third-order sequences, with depositional environments confined to the shelf and consisting mainly of fluvial elements. Sequence boundaries (SB) apparently result from major sea level falls, since there was no tectonic uplift and the field underwent only regional slow subsidence during sedimentation of the study interval. Sea level fluctuation also caused changes in fluvial patterns. Analysis of changing channel patterns indicates that major systems tracts relate to specific channel patterns. The Lowstand Systems Tract (LST) is generally dominated by larger channel dimensions and low sinuosity channel patterns. The Transgressive Systems Tract (TST) typically contains relatively smaller channels with high sinuosity. Channels in the Highstand Systems Tract (HST) generally show moderate sinuosity channels and are intermediate in size, larger than TST channels but smaller than LST channels. Crossplots of stratigraphic position and channel morphology indicate that within the transition from LST-TST, channel dimensions (width and thickness) generally decrease and channel sinuosity generally increases. High sinuosity, meandering and anastomosing channels are generally found near the maximum flooding surface. Low sinuosity channels occur within the HST-SB-LST succession, with the exception of higher sinuosity meandering channels evolving inside valleys. Larger, lower sinuosity channels result from high gradient and high discharge associated with stream piracy. Smaller, high-sinuosity channels result from low gradient and small discharge. Extraction of seismic attributes such as RMS Amplitude and Average Reflection Strength show these depositional features in greater detail. In the Belida Field area, lowstand channels were found to comprise the greatest volume of sandstone bodies. Seismic delineation of the distribution and morphology of these channel systems provides critical input for reservoir modeling and volumetric analysis.

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:
Les deltas fluviaux sont des écosystèmes riches et vulnérables. Les apports de sédiments fluviaux assurent leur développement face à la subsidence et l’érosion induite par les agents marins. Les deltas sont principalement exposés à des crues et des submersions marines. Pourtant, ils restent des lieux stratégiques de peuplement, de production économique et d’enjeux géopolitiques, les rendant d’autant plus vulnérables et exposés aux risques. Cette thèse a pour objectif de cerner le fonctionnement passé et actuel de ces systèmes à partir de l’analyse de soixante deltas et d’une approche holistique systémique, à l’aide de données spatiales, environnementales et sociétales. Après l’étude de l’évolution côtière récente montrant une tendance à la diminution de la progradation de nombreux deltas, une classification conceptuelle et qualitative de la morphologie des deltas axée sur les influences fluviomarines a été conduite. La mise à jour de cette classification et la proposition de nouvelles approches, en termes de morphologie, de dynamique et de vulnérabilité, ont nécessité une revue des acquis antérieurs, une quantification de l’influence du fleuve, de la houle et de la marée, et une approche quantitative qui a mis en évidence la complexité des interactions. Le travail débouche sur une nouvelle classification quantitative et objective. La thèse compare aussi les réponses deltaïques à des perturbations exceptionnelles, montrant les limites de la résilience deltaïque. Elle renseigne sur l'impact anthropique sur ces espaces fragiles fortement dépendants de l’apport sédimentaire. Cet équilibre est d’autant plus fragilisé aujourd’hui par les impacts du changement climatique<br>River deltas are rich and fragile ecosystems. Deltas depend on fluvial sediment supply to balance natural subsidence and erosion caused by waves and currents. Deltas are mainly affected by river flooding, marine submersion. However, deltas are strategic sites of human settlement, economic hotspots, and geopolitical issues. This attraction increases the pressure, rendering these deltas more and more exposed to risks and vulnerable.The main objective of this thesis is to analyze the past and present functional dynamics of delta shorelines based on 60 of the world’s deltas and a holistic and systemic approach with spatial, environmental, and societal data. After the study of recent coastal evolution showing a tendency to decreasing progradation of many deltas, a conceptual and qualitative classification of deltaic morphology based on fluviomarine influences was conducted. Updating of this classification and the proposal of new approaches, in terms of morphology, dynamics, and vulnerability, have necessitated revisiting these older schemes, and the adoption of a methodological and interpretative approach aimed at quantification of the weight of each of these three parameters showing the complexity of the interactions. The thesis proposes a new quantitative and objective classificatory framework, including the human dimension. Finally, the thesis highlights the responses of deltaic shorelines to exceptional perturbations, and highlights the limits of resilience. The thesis advises over the impact of humans on these fragile coastal environments, the equilibrium of which strongly depends on sediment supply. This fragility is further exacerbated by the impacts of climate change

Abstract:
Changes in external forcing having traditionally been the main area of interest in trying to understand paleo-depositional environments in sedimentary systems; however, autogenic variability has been rising in importance, while autogenic behavior has been thought of as a “noise” generator. Recently, autogenic variability has been rising in attention because decoupling allogenic signatures (externally driven) from the stratigraphic record requires robust understanding of autogenic variations (internally generated). This study aims to quantitatively measure autogenic processes under a range of flux conditions and to show that autogenic processes generate distinct signatures rather than random noise. We present data from a matrix of nine different tank experiments in order to systematically evaluate the effects of sediment flux and water discharge variations on the autogenic timescale of fluvial sediment storage and release processes and the implications of this data to the stratigraphic record. The sediment flux tow ater discharge ratio and the absolute values of these two discharges control the autogenic timescale. Variations in sediment supply yield two competing effects on the autogenic timescale. The primary sediment flux control causes a reduction in the autogenic timescale as an increase in sediment supply yields an increased rate of filling the “fluvial envelope” (the space between the maximum and minimum fluvial slopes obtained during storage and release events). In contrast, the secondary sediment flux control increases the size of the fluvial envelope and works against the primary sediment flux control. Increasing the water discharge increases the autogenic timescale by widening the fluvial envelope during the organization of the fluvial system and more importantly, diminishes the functionality of the secondary sediment control. A competition exists between these factors, causing a non-linear range of autogenic timescales for a given sediment flux to water discharge ratio. In the nine experiments here, as the ratio decreases, the secondary effects of variations in sediment supply are suppressed by the relatively high water discharge, and the timescale is more predictable using the primary sediment control. As the ratio increases, the secondary effects from sediment supply are enhanced by a poorly organized fluvial system, and the timescale converges to a narrow range. This suggests significant implications for autogenic sediment delivery and stratigraphic development in a wide range of discharge conditions in field cases.<br>text

Abstract:
ABSTRACT Mohawk Valley lies in northeastern California on the margin of the northernmost Sierra Nevada and was occupied by Mohawk Lake during much of the middle and late Pleistocene. Throughout that time, the Sierra Nevada ice cap repeatedly extended northward into Mohawk Lake, and ice-contact deltaic sediments were deposited along the valley margins and in the valley bottom. Nearly 200 m of lacustrine and deltaic sediments are now well exposed along streams draining the Sierra Nevada. Tephra beds deposited within the deltaic sediments allow correlation of stratigraphic sections around the valley margin and, together with geomorphic evidence of former lake levels, permit interpretation of a Mohawk Lake history as far back as 740 ka. Mohawk Valley changed from a through-flowing fluvial setting to an intermittent closed basin sometime before 740 ka. After this change occurred, relatively small lakes intermittently formed in Mohawk Valley until ca. 600 ka, when the lake dramatically deepened. Mohawk Lake fluctuated in size over the next ~400,000 yr and increased in size to its highest levels after ca. 200 ka, possibly due to drainage integration with the upstream Lake Beckwourth. After this time, Mohawk Lake spilled over its westward sill, incrementally eroding and lowering lake levels until Mohawk Lake was emptied by ca. 7 ka.

Abstract:
&lt;em&gt;Abstract&lt;/em&gt;.—The lower Mississippi River encompasses the 1,535-km reach extending from the confluence with the Ohio River at Cairo, Illinois to the Gulf of Mexico. Waters of the lower Mississippi River have historically inundated vast areas of adjacent floodplain during spring flood pulses. Additionally, processes of land building within the river’s deltaic plain supported vast forests and diverse freshwater and salt-marsh habitats. Flood pulses provided a mechanism of lateral exchange of energy and nutrients between the aquatic and terrestrial habitats, while sediment loads continually rebuilt and supported the deltaic plain. As human populations and agriculture expanded throughout the lower Mississippi Valley, construction of flood-protection levee systems and commercial navigational structures severely decreased the connectivity between the lower Mississippi River and its floodplain. The current lower Mississippi River floodplain is more than 90% reduced in area compared to historical conditions. Fluvial dynamics, which are the driving forces that stimulate floodplain function and create diverse habitats, appear to have been altered throughout approximately 80% of the river. As a result, the hydrograph, thermograph, sedimentation patterns, nutrient dynamics, and vegetation communities within the lower Mississippi River floodplain have experienced major changes through time, with many large alterations occurring during the past century. In addition, because most of the sediment load of the lower Mississippi River now enters the northern Gulf of Mexico, land building and associated processes are much reduced in the river’s deltaic plain. This process has allowed intrusion of saltwater into coastal habitats, which has heavily impacted vegetation communities. This paper reviews the consequences of river modification to lower Mississippi River floodplain, current efforts towards restoring the floodplain and deltaic plain, and proposes future strategies towards restoring portions of the historical floodplain.

Abstract:
Abstract Understanding and characterizing the behaviour of the subsurface by combining it with a suitable statistical method gives a higher level of confidence in the reservoir model produced. Interpolation of porosity and permeability data with minimum error and high accuracy is, therefore, essential in reservoir modeling. The most widely used interpolation algorithm, kriging, with enough well data is the best linear unbiased estimator. This research sought to compare the applicability and competitiveness of inverse distance weighting (IDW) method using power index of 1, 2 and 4 to kriging when there is sparse data, due to time and budget constraints, to calculate hydrocarbon volumes in a fluvial-deltaic reservoir. Interpolation results, estimated from descriptive statistics, were insignificant and showed similar prediction accuracy and consistency but IDW with power index of 1 indicated the least error estimation and higher accuracy. The assessment of hydrocarbon volume calculations also showed a marginal difference below 0.08 between IDW power index of 1 and kriging in the reservoir zones. Reservoir segments cross-validation and correlation analysis results indicate IDW to have no significant difference to kriging with absolute errors of 3% for recoverable oil and 0.7% for recoverable gas. Grid upscaling, which usually causes a loss of geological features and extreme porosity values, did not impact the results but rather complemented the robustness of IDW in both fine and coarse grid upscale. With IDW exhibiting least errors and higher accuracy, the volumetric and statistical results confirm that when there are fewer well data in a fluvial-deltaic reservoir, the suitable spatial interpolation choice should be IDW method with a power index of 1.
