1. Recent Developments on the Elucidation of Colloidal Aspects of Asphaltenes and Their Relevance to Oilfield Problems
Asphaltenes constitute the heavy petroleum fraction responsible for deposition events that may lead to reduced oil production, therefore of great interest for flow assurance. These molecules self-assemble in solutions leading to formation of aggregates that eventually grow towards precipitation and blockages in reservoirs and pipelines. Based on the Yen-Mull

2. AVALIAÇÃO DE ASFALTENOS PRECIPITADOS EM DIFERENTES CONDIÇÕES DE COMPOSIÇÃO, TEMPERATURA E PRESSÃO
Asphaltenes are a heavy fraction of petroleum with the ability for self-association, a phenomenon that can occur spontaneously in the reservoirs or in any of the various stages of production and processing, depending on variations in pressure, temperature, composition and shearing, among others. In this work, it was evaluated the precipitation of asphaltenes

3. Streptomyces lunalinharesii 235 prevents the formation of a sulfate-reducing bacterial biofilm
ABSTRACT Streptomyces lunalinharesii strain 235 produces an antimicrobial substance that is active against sulfate reducing bacteria, the major bacterial group responsible for biofilm formation and biocorrosion in petroleum reservoirs. The use of this antimicrobial substance for sulfate reducing bacteria control is therefore a promising alternative to chemic

4. 3D COMPOSITIONAL RESERVOIR SIMULATION IN CONJUNCTION WITH UNSTRUCTURED GRIDS
Abstract In the last decade, unstructured grids have been a very important step in the development of petroleum reservoir simulators. In fact, the so-called third generation simulators are based on Perpendicular Bisection (PEBI) unstructured grids. Nevertheless, the use of PEBI grids is not very general when full anisotropic reservoirs are modeled. Another p

5. Evaluation of chemical and mechanical resistance of virgin and recycled poly (ethylene terephthalate) and poly(methylene oxide) when applied as gravel pack in petroleum wells
AbstractNowadays more and more unexpected uses for common materials have been observed, especially when recycled polymers are concerned. In this work, the viability for application of virgin and recycled poly(ethylene terephthalate) (PETvir and PETrec, respectively) and also poly(methylene oxide) (PMO) as granular materials (gravel) for gravel packing in san

6. Terpanos pentacíclicos como indicadores de heterogeneidades composicionais em reservatório de petróleo biodegradado
Reservoir geochemistry has been effectively used to evaluate compositional heterogeneity in petroleum reservoirs by employing oil fingerprinting technique to assess reservoir continuity, primarily in paraffin oil accumulations. In-reservoir biodegradation has resulted in vast deposits of heavy oils globally; therefore, the application of reservoir geochemist

7. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

8. Simulation of multiple reservoirs sharing constrained surface facilities using integrated production modelling / Simulação de múltiplos reservatórios em cenário com restrição de superfície utilizando modelagem integrada de produção
The selection of production strategies for petroleum field development is an important task. The specific case in which there are constrained surface facilities, the allocation of production and injection well rates is one more item to be optimized. When the problem involves several segregated reservoir units, each of which characterized by its own geologica

9. Simulação da recuperação de petróleo em reservatórios naturalmente fraturados / Simulation of petroleum recovery in naturally fractured reservoirs
A recuperação de petróleo em reservatórios naturalmente fraturados apresenta-se como um risco de projeto, sobretudo em sistemas molháveis ao óleo ou com molhabilidade intermediária, já que a simulação utilizando deslocamento por injeção de água indica significativa redução da recuperação. As fraturas representam descontinuidades do meio poro

10. Análise de dados de testes de formação frente aos efeitos de maré / Analysis of well test data against tide effects
Efeito de maré é o nome dado a um fenômeno observado em dados de pressão registrados em acumulações de fluido, incluindo reservatórios de petróleo, e que tem origem na variação do potencial gravitacional a que as massas estão submetidas. As primeiras citações do efeito de maré observado em reservatórios de petróleo ocorreram em meados da déc

11. Processos naturais de biodegradação do petróleo em reservatórios
Petroleum biodegradation in reservoirs is a process caused by different microorganisms affecting many oil deposits which modifies the oil composition in a quasi-stepwise process starting from n-alkanes and isoprenoids through to diasteranes. This causes oil souring and increased viscosity, sulfur and metal content, having a direct impact on oil production an

12. Caracterização estrutural e funcional de genes de degradação de hidrocarbonetos originados de metagenoma microbiano de reservatórios de petróleo / Structural and functional characterization of hydrocarbon degradation genes from microbial metagenome derived from petroleum reservoirs
A ocorrência de óleos biodegradados nos reservatórios de petróleo, juntamente com o isolamento das primeiras bactérias a partir destes ambientes, forneceu evidências de micro-organismos ativos no subsolo profundo. Os micro-organismos, habitantes comuns de reservatórios de petróleo, desenvolveram estratégias eficazes de biodegradação, baseados em s
