1. 3-D Geological modelling: a siliciclastic reservoir case study from Campos Basin, Brazil
Abstract Reservoir static modelling plays a fundamental role in the evaluation phase of a petroleum field. Integrated modelling allows a better understanding of how the local geology and depositional systems are related through the distribution of facies and petrophysical properties within the reservoir. In this study, geological static models of the silicic

2. Estudo de propriedades petrofísicas de rochas sedimentares por Ressonância Magnética Nuclear / Petrophysical properties study of sedimentary rocks by Nuclear Magnetic Resonance
The Nuclear Magnetic Resonance (NMR) technique is one of the most versatile techniques for scientific research, specially for the study of dynamics, structure and conformational of materials. In particular, its application in oil science is one of its first routine applications. Methodologies developed specifically to match this scientific community proved t

3. Inversão sísmica para impedância acústica na caracterização de reservatórios : impacto da extração da wavelet e do aumento da banda de frequências / Seismic inversion to acoustic impedance in reservoir caracterization : the impact of wavelet extraction and increase the frequency band
The substrates that constitute a reservoir are identified using seismic data. The process consists of determining reservoir petrophysical properties. However, sub-seismic layers structures are masked due to the limitation of conventional seismic data. The failure provided by these data produces an erroneous model of reservoir. The lack of vertical resolution

4. Análise de modelos geológicos utilizando percolação dinâmica
In the present study we elaborated algorithms by using concepts from percolation theory which analyze the connectivity conditions in geological models of petroleum reservoirs. From the petrophysical parameters such as permeability, porosity, transmittivity and others, which may be generated by any statistical process, it is possible to determine the portion

5. AJUSTE AUTOMÁTICO DE HISTÓRICO EM RESERVATÓRIOS DE PETRÓLEO UTILIZANDO O MÉTODO TSVD / AJUSTE AUTOMÁTICO DE HISTÓRICO EM RESERVATÓRIOS DE PETRÓLEO UTILIZANDO O MÉTODO TSVD
Reservoir simulation is an essential tool extensively used by reservoir engineers. It is mostly employed to predict reservoir behavior under dfferent circumstances, thus supporting decisions that frequently involve large nancial costs. In order to use this tool properly different petro-physical properties of the reservoir must be well known, such as permeabi

6. Impacto da modelagem estocastica no processo de caracterização de reservatorios maduros / Impact of the stochastic modeling on mature reservoirs characterization process
A consistent geologic modeling is necessary to evaluate the petroleum reservoirs. In mature field, a large amount of remaining oil exists and, many times, with good capacity of being recovered. For this, geostatistical techniques are used for construction of solid models that allow to locate and to quantify this remaining oil. In a reservoir characterization

7. Prediction of petrophysical properties by 3D reconstruction of porous media from image analysis / Estimativa de propriedades petrofisicas atraves da reconstrução 3D do meio poroso a partir da analise de imagens
Este trabalho tem como objetivos o estudo e a aplicação do processo de estimativa de propriedades petrofisicas a partir de informações obtidas em imagens petrográficas bidimensionais. O método assume a hipótese da homogeneidade estatística, e utiliza a simulação estocástica para a reconstrução do modelo tridimensional do meio poroso. A caracteri

8. Visualização e analise do deslocamento imiscivel e instavel em meio poroso consolidado
The main objective of this study is to investigate, at laboratory scale, the influence of both displacement velocity and mobility ratio on the relative permeability and geometry of two phase immiscible flow, in a naturally consolidated porous medium, in the presence of conate water saturation. The displacement experiments were carried out in cylindrical core

9. Impactos das incertezas geologicas nos resultados de uma simulação de fluxo : aplicação em um caso real
This dissertation investigates the impacts in the results of flow simulation due to four points of uncertainty: the variability between realizations of stochastic simulation of fades, the variability between realizations of petrophysical properties modelling, the application of up-scalling methods and the types of models for the structuring of flow simulatio

10. Caracterização geologica de um reservatorio fluvio-eolico da Bacia do Reconcavo-Bahia, Brasil
This dissertation presents a detailed study of an Early Cretaceous, fluvial-aeolian reservoir from the Recôncavo Basin, northeastern Brazil. This study, developed at the oil field scale, inc1uded essentially: (1) the description of lithofacies and lithofacies associations, as well as their depositional processes; (2) the interpretation of depositional syste
