s Coefficient and Lorenz Coefficients. This study compared core and well test measurements in South East of Turkey heavy oil carbonate field. An evaluation of well test data and associated core plug data sets from a single field will be resulting from the interpretation of small (core) and reservoir (well test) scale permeability data. The techniques that were used are traditional volume averaging/homogenization methods with the contribution of determining permeability heterogeneities of facies at each step of upscaling procedure and manipulating the data which is not proper to be averaged (approximately normally distributed) with the combination of Lorenz Plot to identify the flowing intervals. As a result, geometrical average of upscaled core plug permeability data is found to be approximately equal to the well test derived permeability for the goodly interpreted well tests. Carbonates are very heterogeneous and this exercise will also be instructive in understanding the heterogeneity for the guidance of reservoir models in such a system.

This research presents a workflow integrating several post-stack seismic attributes to assist in understanding the development history of Weirman Field, Ness County, KS. This study contributes to shaping future drilling plans by establishing a workflow combining analysis of seismic attributes and well cuttings to locate a channel fill zone of better reservoir quality, and to highlight reservoir boundaries due to compartmentalization. In this study, I have successfully outlined a fluvial channel, which is expected to be significantly different in terms of petrophysical properties. The Pennsylvanian aged Cherokee sandstones that potentially comprise channel fill lithofacies, in this study, have been linked to oil production throughout the state of Kansas. It is important to understand channel sandstones when evaluating drilling prospects, because of their potential as an oil reservoir and unpredictable shapes and locations. Since their introduction in the 1970s, seismic attributes have become an essential part of lithological and petrophysical characterization of hydrocarbon reservoirs. Seismic attributes can correlate to and help reveal certain subsurface characteristics and specific geobodies that cannot be distinguished otherwise. Extracting and analyzing acoustic impedance, root-mean-square amplitude and amplitude attenuation, guided by a time window focused on the top of the Mississippian formation, resulted in an understanding of the key seismic channel-facies framework and helped to explain some of the disappointing drilling results at Weirman Field. To form a better understanding of these seismic attributes, this study combined certain attributes and overlayed them in partially transparent states in order to summarize and better visualize the resulting data. A preliminary study of spectral decomposition, which was introduced in the late 1990s, was preformed, and a more in-depth study of this multi-resolution attribute is recommended for future study of this particular field. This study also recommends integrating the revealed compartmentalization boundary and the seismic channel-facies framework in future drilling plans of Weirman Field.

Resumo: O uso método de análise multivariada ICA (Análise de Componentes Independentes), mais o método K-NN (K-vizinhos mais Próximos) aplicados em dados de poços e em dados sísmicos buscando classificar fácies geológicas e suas características. Esses dois métodos foram aplicados em dados retirados do Campo de Namorado, na Bacia de Campos, Brasil. A ICA encontra as componentes independentes dos dados, que quando treinadas pelo método K-NN para reconhecer padrões nos dados, predizem fácies geológicas e outras informações sobre as rochas, como as características de reservatório. Essas componentes independentes configuram uma nova opção de interpretação das informações disponíveis, pois nessas novas variáveis, o espaço de análise não apresenta dimensões dependentes e exclui informações repetidas ou dúbias da interpretação dos resultados. Além disso, a maior parte da informação é resumida em poucas dimensões, resultando em uma possível redução de variáveis referentes ao problema. Um abundante número de testes foi feito procurando a taxa de sucesso desse método. Como taxa de sucesso, é compreendida a divisão do número de predições corretas dividido pelo número total de tentativas. O que se observa é uma taxa de sucesso alta, em torno de 85% de acerto em algumas situações, ressaltando-se que as componentes têm distribuição gaussiana, sendo que o método funciona melhor em encontrar componentes não-gaussianas. Mesmo nessa situação adversa o método se mostrou robusto. A solidez do método mostra-se uma alternativa para novas formas de interpretação geológicas e petrofísicas. Um dos trunfos desse método é que a base da sua aplicação pode ser estendida para outros tipos de dados, inclusive de naturezas físicas diferentes
Abstract: The use of multivariate analysis method ICA (Independent Component Analysis), plus the K-NN method (K-nearest Neighbor) applied on well log data and seismic data to predict the classification of geological facies and their characteristics. These two methods were applied to data from the Campo de Namorado, in the Campos Basin, Brasil. The ICA finds the independent components of the data that can be trained by K-NN method to recognize patterns in the data and predict the geological facies or other information about the rocks, as the characteristics of the reservoir. These independent components make up a new option for interpretation of available information, because with these new variables, the space has no dependent dimensions and the duplicate information or dubious interpretation of results are excluded. Moreover, most of the information is summarized in a few dimensions, resulting in a possible reduction of variables related to the problem. An abundant number of tests were done looking for the success rate of this method. As success rate, it is understood by the division of the number of correct predictions divided by total attempts. What is observed is a high success rate, around 85% accuracy in some situations, pointing out that the components have a Gaussian distribution and the method works best in finding non-Gaussian components. Even in this adverse situation the method was robust. The robustness of the method proves that ICA can be an alternative to new forms of geological and petrophysical interpretation. One of the advantages of this method is that the basis of their application can be extended to other types of data, including datas with different physical natures

Resumo: O presente trabalho é uma análise vertical de depósitos marinhos profundos, cujos processos deposicionais se dá por fluxos gravitaticionais, na Unidade Apiúna, na Bacia do Itajaí, Estado de Santa Catarina. Os dados estão dispostos em 5 seções, das quais as 4 primeiras são correlacionáveis, com aproximadamente 200 metros de espessura total, 524 camadas e 102 transições de fácies. Em que a média das camadas é de 25 cm. Através da transformada de Fourier, no domínio da freqüência obteve-se os seguintes dados: nenhum ciclo na seção 1; 2 ciclos na seção 2; 11 ciclos na seção 3; 6 ciclos na seção 4; 4 ciclos na seção 5 e 16 ciclos nas seções 1-4, que puderam ser correlacionáveis. As freqüências (ciclos), foram definidas com o auxílio da análise visual da seções. Com relação aos ciclos de afinamento ou engrossamento ascendente (megassequências), os resultados foram: engrossamento ascendente: 2 na seção 2, 6 na seção 3, 2 na seção 4 e 18 na seçôes 1-4, enquanto que o afinamento ascendente:3 na seção 3,3 na seção 4,3 na seção 5 e 10 nas seções 1-4. Existe diferença entre a análise visual e a função da freqüência, porém as megassequências, foram definidas segundo a análise visual. A análise de Markov corrobora que as principais transições estão inseridas num contexto de lençóis de areia, proximais e distais, em que ocorre a intercalação de arenitos fino a médio, intercalados com finas camadas de arenito com siltito, respectivamente fácies D e E. Diante de tais observações foi possível refutar a inclusão da Unidade Apiúna, num clássico depósito de leques profundos supridos por canyon, pois como largamente disposto na literatura, este depósitos apresentam seqüências de engrossamento ou afinamento ascendente (thinning e thickening upward), o que se expressa nas 5 seções de maneira bastante tímida. Quanto aos trends de granulometria, que pode refletir que o mecanismo de deposição, o fluxo de detritos (debris flow) é dominante, em detrimento de correntes de turbidez (turbidite currents), isto porque não é comum a gradação ascendente nas camadas de arenito, sendo somente no topo de algumas camadas que ocorrem este último fenômeno. Foi possível diferenciar quatro associações de fácies, numeradas de 1 a 4 a seguir: depósitos de slope, depósitos de lençóis de areia proximais, depósitos de lençóis de areia distais e finalmente depósitos de canal-dique marginal
Abstract: This work is a vertical analysis of deepwater deposits outcrops, whose depositional processes occurs by gravity flows in the Apiúna Unit, Itajaí Basin, Santa Catarina State. The data are organized in 5 sections where each section is one outcrop. The sections from 1 to 4 have mutual correlation, with almost 200 m of total thickness, 534 beds and 102 facies transitions. Through Fourier transform, in the frequency domain, 16 sequences was obtained, defined by visual analysis of thickness beds. The results for the sequences of thinning and thickening upward were: 10 of thickening upward and 6 of thinning upward. The vertical trends of fining upward are often randomic. The use of Markov Chain's tooI confirmed the main facies transitions which are located in a context of sheet sands, proximal and distal, in which occurs the superposition of fine to medium (D facies) sandstones with the thin beds of sandstone and siltstone (E facies ). According to the data above, it was possible to refuse the Apiuna Unit as a classical canyon-fed deposits of deep water fan, because of absence of better defined and low abundant sequences of thinning and thickening upward. The debris flow is the main depositional processes, while turbidity currents occur in the upper part of flow in some sandstone beds. This configuration is showed in the beds with the trend of fining upward. It was possible to identify four facies associations, namely: slope deposits; proximal sheet sands; distal sheet sands and channel-levee

Повний текст джерелаLes attributs sismiques ont comme caractéristique de pouvoir décrire et quantifier les données sismiques, de telle manière qu’ils représentent un sous-ensemble de l’information totale contenue dans les données originales. En conséquence, les attributs sismiques peuvent être d’importants paramètres qualitatifs et quantitatifs des propriétés physiques d’un réservoir. L’analyse d’attributs sismiques a commencé avec la prospection de tâches lumineuses (<< bright spots >>) vers la fin des années 1960 et début des années 1970. Des travaux subséquents pendant les dernières décennies ont permis d’établir l’analyse d’attributs sismiques comme un outil valable lors d’études de caractérisation d’un réservoir. Je présente dans cette thèse deux études d’attributs sismiques pour l’interprétation de la forme de la trace sismique afin de prédire des caractéristiques géologiques significatives tels que: la lithologie, les propriétés des roches et/ou le contenu liquide. La première étude est un exemple de l’application d’attributs sismiques pour prédire des contrôles géologiques sur la production d’un réservoir coalbed methane. D’après les résultats de la calibration des diagraphies au câble avec des données sismiques, j’ai défini une fenêtre d’investigation à partir de laquelle des attributs sismiques de type amplitude, fréquence et phase ont été calculés. J’ai utilisé une analyse muIti-attribut pour dériver un model statistique dans le but d’estimer l’épaisseur du réservoir. Par la suite, j’ai utilisé des attributs mesurant la courbature d’une surface pour mettre en relief de subtiles structures géologiques et prédire les régions dans le réservoir avec une perméabilité augmentée. L’intégration des données de production avec les résultats obtenus lors d’analyses d’attributs sismiques indique que la meilleure production est en association avec l’épaississement du réservoir et le voisinage immédiat de structures géologiques.

Повний текст джерелаThe Upper Ordovician Maquoketa Group equivalent strata in Indiana and Ohio were part of a westward-thinning shale-dominant succession. Large amounts of fine-grained siliciclastics were shed from the eastern highlands during the Taconic Orogeny.
The detailed lithofacies analysis of the Upper Ordovician shales has yielded recognition of a series of genetically related sequences in a seemingly homogenous succession. The lower succession is pyritic laminated/banded organic-rich mudstone that accumulated after the onset of a major flooding event. Cryptobioturbation, bottom current ripples, graded silt/clay couplets and well preserved benthic fossils indicate an oxygen-depleted dysoxic condition. In addition, layers enriched in phosphatic fossils, phosphate and pyritic grains appear to mark flooding surfaces and sediment starvation. The maximum organic-matter enrichment mainly occurred within black homogenized mudstone in the middle succession. Upsection, more extensive bioturbation and carbonate production are observed. The intermittent yet frequent wave and current activity, suggested by cross-lamination, wavy-lenticular stratification and hummocky cross stratification, indicate a shallower and proximal settings with enhanced sediment influx.
The deposition of the Upper Ordovician shales in the Maquoketa Group reflects a complex interplay between storms, sediment supply, and eustatic sea-level changes. Nonetheless, with distinct characteristics of lithofacies, wireline logs, and organic carbon isotope data, a high-resolution sequence stratigraphic framework of the Upper Ordovician shales can be compiled for the study area. The whole studied interval comprises an entire 3rd order sequence, wherein the lower part appears to be a transgressive systems tract and the remaining overlying strata represent a highstand systems tract. This project is an example how integration of sedimentological observations, geophysical data, petrographical and geochemical data enable a better understanding of the accumulation of this mudstone succession in a regional sequence stratigraphic context.

Повний текст джерелаThe analysis of sedimentology, geometry and trajectory of successive deltaic clinoforms in outcrop-based studies or in high-resolution reflection seismic datasets has been widely employed as a tool to (1) infer relative sea-level changes and (2) to interpret short and long-term factors controlling basin margin evolution and timing of coarse-grained sediment delivery from continents to oceans. Sea-level (accommodation) and sediment supply-driven models have been developed mainly on large-scale seismic data, with less focus on sedimentary facies analysis and inferred depositional processes in operation at different positions along individual clinothems, and how these process change with trajectory and time. The Lower Eocene Castissent depositional sequences (Castissent Group, South-Central Pyrenees, Spain) mainly consist, in the Ainsa basin, in mouth-bar deposits and delta front sandstone lobes in transition to slope turbidites, deposited in a flood-dominated river-delta system. Deposition of these bodies was strongly controlled by the interaction between continental-derived hyperpycnal flows, the influence of shoreline processes over these flows and the local and regional tectonic activity, whose syn-sedimentary thrust-and-fold kinematics has not been explained in enough detail yet. Field mapping and correlation of high-frequency cycles show that they can be considered deltaic clinothems bounded by clinoform surfaces (their sigmoid bounding unconformities) whose formation is strictly controlled by tectonics. Moreover, high resolution seismic profiles tied to cored and dated boreholes data provide a means to link the depositional architecture (clinoform trajectory) to sediment dispersal processes and patterns. IODP Expedition 313 cored a set of Miocene clinothems offshore New Jersey to capture a complete record of sea-level change through integration of seismic stratigraphy, core and well logs, and chonostratigraphy. In the Expedition 313 dataset, this analysis can be performed over successive clinothems, with the assessment of sedimentary facies and process-based interpretations of environments of deposition down a single clinothem (Poyatos-Moré and Hodgson, 2012; Hodgson et al., in prep.). However, some outcrop-based studies like the Castissent sequences or subsurface-based studies like the New Jersey margin commonly treat accommodation and sediment supply as a 2D problem, by analyzing a margin profile parallel to the main sediment route. The results of these works have been compared with the lower Waterford Formation (Karoo basin, South-Africa), which provides a 3D outcrop-based case study of an exhumed shelf-to-slope system that allows the identification of clinoform rollover positions and depositional facies associations along three depositional dip profiles (Jones, 2013; Jones et al., 2013a and b). These parallel basin margin profiles of the lower Waterford Formation show all broadly similar trajectories, although with a significant along-margin variability. Thus, strike variability in basin margin physiography strongly affects sediment dispersal between shelf, slope and basin floor settings and it must be therefore considered together with process regime as a key controlling factor when attempting stratigraphic predictions of sediment bypass in shelf-margin successions.

Повний текст джерелаThe intracratonic orogenesis of the Petermann Orogeny caused the formation of high-pressure, low-geothermal gradient, eclogite facies rocks. These geologically rare rocks are found in the exposed orogenic core, observable near the Traditional community of Amata, in the Musgrave Province. Their formation remains a mystery and as a result two contrasting models have been proposed to explain their formation; namely whether orogenesis occurred in “hot” crust and was long lived, or occurred in “cold” crust and was short-lived. In situ LA-ICP-MS analysis of monazite show that metamorphism occurred at c. 598 Ma. Using conventional thermobarometric techniques, peak conditions are estimated to have reached ~640 °C and ~11.5 kbar. Integrating this data with petrological observations and calculated P-T pseudosections, a clock-wise P-T path was defined, which is typical of an orogenic setting. Diffusion modelling using garnet compositional profiles from grains of both relict composition and those interpreted to be reset, estimated the minimum duration for prograde metamorphism to be ~27 Myr. The same garnet grains show little to no evidence of cooling/exhumation, which has been attributed to the low metamorphic peak temperature. Results of this study make a direct contribution to two contrasting models for orogenesis. Combining new evidence from this study with tectonothermal evidence from the western Musgrave Province and sedimentological data from the Officer Basin to the south, it is concluded that shear heating (or short-lived deformation) is not a plausible model for Petermann-aged deformation. Despite the lack of spatially continuous data across the Musgrave Province, long-lived orogenesis is the more supported model in light of new evidence emerging from this study.

Повний текст джерелаThe Elatina Formation is exposed in outcrops throughout South Australia, most notably represented by distinct glaciogenic deposits in central and northern Flinders Ranges. As the formation reflects low latitude glaciation, it has previously been used as a benchmark study in the development of the Snowball Earth hypothesis. Pichi Richi Pass in the central Flinders Ranges is an excellent example of the Elatina Formation, however significant uncertainties exist regarding the local sequence stratigraphy and interpretation of the depositional environments. A detailed facies analysis and 3D model of the Elatina Formation at Pichi Richi Pass was established to demonstrate the variability and distribution of the depositional system. The Elatina Formation consists of four lithostratigraphic units, with eight facies identified within two of the units. The facies were established from lithological properties, and then associated based on descriptions and interpretation of their depositional processes. The results reflect thick non-glaciogenic layers interbedded with thin glaciogenic layers. The non-glaciogenic layers were deposited in coastal, deltaic and fluvial settings, while the glaciogenic units were deposited in a glaciofluvial environment. As most of the Elatina Formation in Pichi Richi Pass appears to be deposited under moving water, it suggests that the palaeoenvironment of the Elatina Formation is not consistent with prolonged glacial conditions like that of Snowball Earth. Rather, it denotes variable glacial periods characterised by glacial advance and retreat.

Повний текст джерелаCarbon, oxygen and strontium isotope stratigraphy has increased the resolution of Proterozoic stratigraphic correlation. Isotopic analysis was performed on the late Proterozoic Wonoka Formation canyon and carbonate platform sequences. Highly depleted and homogenised carbon and oxygen isotopes characterise the canyon fill (13C = -8 to -7%o, (18O = - 17 to -15%o PDB ) whilst a major positive excursion was observed in the Wonoka Formation carbonate platform sequence ((13C = -8 to -0.5%o, (18O = -15.0 to -7.0%o PDB). These values correlate closely with other established isotopic trends throughout the Adelaide Geosyncline. However, similar aged late Vendian strata throughout the world show low positive values. Strontium isotopic analysis revealed relatively 87Sr enrichment in the carbonate platform deposits compared to the canyon sequence. This was attributed to the input of 87Sr enriched terrestrially derived strontium. The 87Sr/86Sr ratio of the Wonoka Formation correlates closely with established late Proterozoic seawater trends. Therefore, a primary strontium isotopic composition is implied for the Wonoka Formation. Major and trace element geochemical analysis (Ca, Mg, Sr, Fe, Mn, and Rb) was performed to assess the diagenetic alteration of the late Proterozoic strata. Samples with low Mn/Sr, high Ca/Sr, high strontium, and low rubidium have the highest probability of preserving a primary geochemical signal. Most samples from the Pichi Richi region analysed plotted under the altered Mn/Sr (<2) and Ca/Sr (<2000) values. The high remnant strontium-concentrations of the Wonoka Formation suggest neomorphism from an aragonitic precursor. Micritic carbonate of the Wonoka Formation was probably a primary marine precipitate of aragonite derived from late Proterozoic supersaturated seas. Therefore, the majority of sediment diagenesis probably occurred in the marine phreatic zone, resulting in the observed primary isotopic composition.

Повний текст джерелаThe middle eocene to early oligocene Bowmans and Lochiel coal deposits of the northern St. Vincent Basin, South Australia have been studied to elucidate their depositional environments. These coals occur within predominantly fluvio-lacustrine transgressive system tract sequences that formed during the initial phase of basin infill. The aforementioned facies are unevenly distributed and their stratigraphic succession highlights evolutionary changes in local palaeoenvironments. Within individual seams the transition from subaquatic to topogenous forest swamps and ultimately ombrogenous conditions is most common. However, over the coal sequence as a whole, conditions evolved from exclusively terrestrial through mixed terrestrial and subaquatic to open water. Also detected were multiple rapid reversals of the water table, especially higher in the sequence, and cyclic patterns reflecting a brief basal subaquatic phase prior to the onset of sustained terrestrial conditions. These patterns suggest a fluctuating, although progressively rising, water table and a balance between accommodation and accumulation.
