13. Banco de dados geológico-geotécnicos com base em sondagens à percussão e uso de SIG: análise espacial da profundidade do lençol freático e do \ N IND.SPT\ para obras de fundação em João Pessoa - PB / Geological-geotechnical Database with SPT sounding data and GIS: spatial analysis of water table level and \ N IND.SPT\ values applied to foundation maps in João Pessoa - PB (Brazil)
Geological-geotechnical databases have been used as important assistant tools in urban and environmental management activities. However, the kind of information necessary for one to work with such tools may not always be available or easily supplied. This work concerns the generation of a Decision Support System undertaken through means of a Geographic Infor

14. Pedoforms mapping at the Águas Emendadas ecological station, Distrito Federal, Brazil.
The great urban and rural development of the Distrito Federal (Federal Administrative District) in Brazil over the last 50 years has led to disordered land use and land occupation. To assess the current environmental scenario, detailed surveys of the available natural resources, especially soils, are required. The objective of this work was to evaluate the s

16. Modelagem geológica por simplóides de Bézier / Geological modeling using Bézier simploids
The exploration and monitoring of a hydrocarbon reservoir demand a very detailed knowledge about the geological structures of the target area. The mathematical and computation representation of this knowledge is a geophysical model. In this thesis, we describe a general system for geophysical modeling based on polynomial finite elements of arbitrary degree.

17. Zoneamento geotécnico com base em krigagem ordinária e equações multiquádricas: barragem de Itaipu / Geotechnical zoning based in ordinary kriging and multiquadric equations: Itaipu Hydroelectric Power Plant
This thesis presents a study based on the zoning of geotechnical parameters resulting from core boring, carried out in the basaltic bedrock located in the area of the Itaipu Hydroelectric Power Plant (Foz do Iguaçu - PR). These zonings were carried out based on the interpolation of the data by means of ordinary kriging and multiquadric equations. The data p

18. Desenvolvimento de dobras e falhas em ambiente distensional: Aplicação da modelagem física
The geological modeling allows, at laboratory scaling, the simulation of the geometric and kinematic evolution of geological structures. The importance of the knowledge of these structures grows when we consider their role in the creation of traps or conduits to oil and water. In the present work we simulated the formation of folds and faults in extensional

19. In-Situ combustion : insights on field project and numerical simulation at laboratory and field scale / Combustão In-Situ : considerações sobre projeto e simulações numéricas em escala de laboratório e de campo
Behavior forecast of reservoirs subjected to in-situ combustion is hard and empirical since besides geological complexities it is necessary to reproduce complex fluid models and several chemical reactions that are part of the process. The work flow for field project usually involves: 1) reservoir screening; 2) thermo-analytical experiments; 3) combustion tub

20. Modelagem espacial de dados aerogeofísicos e interpretação de imagens SAR aplicados ao mapeamento geológico e metalogenético da região central do Domínio Bacajá, Estado do Pará / Spatial modeling of aerogeophysical data and interpretation of SAR images with application to geological and metallogenetic mapping of the central Bacajá Domain, State of Pará, Brazil
O Domínio Bacajá está localizado na parte leste do Cráton Amazônico, no âmbito da Província Maroni-Itacaúnas ou Transamazonas, de idade paleoproterozóica. A interpretação vigente dos limites entre as unidades litoestratigráficas que compõem o Domínio Bacajá foi baseada, sobretudo, em dados aerogeofísicos adquiridos na década de 1970. Entre 2

21. Modelagem e renderizaÃÃo da gÃnese e crescimento de espeleotemas em tempo-real / Modelagem e renderizaÃÃo da gÃnese e crescimento de espeleotemas em tempo-real
Among the many natural phenomena already studied in computer graphics research, the interior of caves remains largely unexplored. We present in this paper a plausible approach, based on Geological studies, for modeling the genesis and growth of speleothems. Speleothems are mineral depositions formed in caves, such as stalactites, stalagmites and columns. Our

22. Estudos geoestatísticos aplicados à um depósito magmático de Ni-Cu / Geoestatiscal studies applied to a Ni-Cu magmatic deposit
The studied deposit is composed of a mafic-ultramafic suite with cupro-nickeliferous sulphide mineralization associates and has an extensive data base with information such as chemical analyses and density, and such as lithologic description on the borehole samples. This work presents the application of different geostatistics techniques with two distinct ai

23. NUMERICAL MODELING OF THE CO2 INJECTION IN SALINE AQUIFERS: INVESTIGATION OF THE RELEVANT PARAMETERS FOR OPTIMIZING THE STORAGE IN CCS ¿ CARBON CAPTURE AND STORAGE PROJECTS / MODELAGEM NUMÉRICA DA INJEÇÃO DE CO2 EM AQÜÍFEROS SALINOS: INVESTIGAÇÃO DOS PARÂMETROS RELEVANTES PARA OTIMIZAR O ARMAZENAMENTO EM PROJETOS DE CCS - CARBON CAPTURE AND STORAGE
This work shows an analysis of the technique of carbon dioxide injection into saline aquifers with the purpose of discharge and storage. The final goal was to obtain the features of the aquifer, and of the injection process, to be selected in order to make the amount of stored CO2 higher and the injection time smaller. Considering such objective it was initi

24. Caracterização geométrica e parametrização de depósitos transacionais recentes e sua aplicação na modelagem de reservatórios petrolíferos
In this beginning of the XXI century, the Geology moves for new ways that demand a capacity to work with different information and new tools. It is within this context that the analog characterization has important in the prediction and understanding the lateral changes in the geometry and facies distribution. In the present work was developed a methodology
