1. Simultaneous prestack seismic inversion in a carbonate reservoir
Abstract We applied a method of Simultaneous Prestack Seismic Inversion (SPSI) in a hydrocarbon field located in the Campos Basin, Brazil. The goal was to study the application of this method to Albian carbonate rocks of the Quissamã Formation. Based on what is found in nearby fields, this Formation potentially contains hydrocarbon accumulations that can be

2. Pb isotope geochemistry and reappraisal of Sr-Nd isotopes of the Cerro Morado basic magmatism (Ischigualasto-Villa Union Triassic basin, NW Argentina): Implications for the mantle sources
ABSTRACT: Sr-Nd-Pb isotopic signatures were determined for silica-undersaturated hypabyssal alkaline basic rocks of the Los Baldecitos Formation in the Cerro Morado area, situated in the Ischigualasto - Vale de la Luna Provincial Park (northernmost San Juan Province, Argentina). The basic rocks show slight variations of the Sr-Nd-Pb isotopes and similar beha

3. 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

4. Redes neurais aplicadas ao estudo de rochas reservatório / Neural networks applied to the study of reservoir rocks
A caracterização de reservatórios é um trabalho complexo, que envolve muitas variáveis com informações em diferentes escalas. Para minimizar incertezas, este trabalho propõe a utilização de redes neurais artificiais, algoritmo computacional inspirado no funcionamento cerebral que mapeia, agrupa e prevê informações a partir de reconhecimento de p

5. Determination of the Representative Elementary Volume for the study of sandstones and siltstones by X-Ray microtomography
X-Ray computerized microtomography (µ-CT) besides providing two-dimensional images (2-D) of the transversal sections of the sample, the biggest attraction of the methodology is the rendering of three-dimensional images (3-D), enabling a more real analysis of the porous structure of the rock. However, the reconstruction, visualization and analysis of such 3-

6. Reproductive plasticity of Hypostomus affinis (Siluriformes: Loricariidae) as a mechanism to adapt to a reservoir with poor habitat complexity
In this work we describe the gonad morphology and spawning season of Hypostomus affinis (Steindachner, 1877) in a tropical reservoir based on 55 males and 125 females. Our aim was to assess eventual adaptations in reproductive tactics developed by this riverine species inhabiting an oligotrophic reservoir with low habitat complexity, few rocks and few other

7. Datação de processos diagenéticos em arenitos-reservatório de hidrocarbonetos : uma revisão conceitual
Geochronology has became a powerfull tool for diagenetic studies in siliciclastic rocks as it supply parameters for the definition of their depositional or diagenetic ages. This development occurred particularly in the last decades, with analytical techniques improvements and application of oil exploration. Sandstones are important hydrocarbon reservoir-rock

8. Cimentação carbonática em reservatórios siliciclásticos : o papel da dolomita
Carbonates are important diagenetic cements in siliciclastic rocks thus important to determine these rocks as hydrocarbon reservoirs. The cement is the material had chemically precipitated partial or totally pore filling, affecting rock values of porosity and permeability. The acknowledgment of diagenetic patterns those are associated to the carbonatic cemen

9. Application of a purge-and-trap system for fixed-NH4+ determination by matrix interference free ion chromatography in oil reservoir rocks
É proposto um método para determinação de NH4+-fixo utilizando um sistema de arraste imerso em um banho ultrassônico para extração de NH3 e cromatografia de íons para determinação de NH4+. O método é mais rápido, simples e sensível (LOD = 4,4 mg g-1 NH4+) que o método clássico Kjeldahl.

10. Reconstrução tridimensional de meios porosos utilizando técnicas de simulated annealing
The characterization of porous materials constitutes a problem of scientific and technological interest. Determination of the macroscopic properties of the porous medias have application in many areas, such as production of petroleum, civil and mechanical engineering, for example. In the present work are presented computational methods to estimate the intrin

11. Relações entre a cobertura vegetal e os meios físicos e antrópicos na Microbacia Córrego dos Veados, Tanque Grande, Guarulhos, SP.
The adoption of micro hydrographic basin as units of environmental studies hás made possible to analyze them in holistic way, as demand this type of research. In this case, this dissertation discusses studies in the area of the reservoir Tanque Grande, located in the city of Guarulhos, São Paulo State, Brazil. For in such a way, it was selected the micro h

12. Porosidade e permeabilidade em amostras de rochas : estudo com alunos do ensino fundamental sobre reservatorio subterraneo / Porosity and permeability in rocks samples : a study with elementary school students about underground water reservoir
O ciclo da água é de fundamental importância. Apesar disso, o tratamento desse tema em livros didáticos de ensino básico pouco contribui para a formação de uma idéia científica. Para enfrentar o tratamento fragmentado presente em livros didáticos de Geografia e Ciências, planejamos atividades diferenciadas para investigar como alunos de 11-12 anos
