13. Study of application of quantitative methods in seismic data in the integrated reservoir characterization process / Estudo de aplicação de metodos quantitativos em dados sismicos no processo de caracterização integrada de reservatorios
The reservoir characterization process can be considered curretly the most important stage in the exploration, development and production of the oil field. However, this process is only carried out in the best way if the geologists, geophisicist and engineering has the knowledge of some definitive methods and techniques that integrated all information availa

14. Simulação do escoamento miscível decorrente da injeção de ácido em um meio poroso com dissolução parcial do meio / Flow simulation of the acid injection in porous media with partial dissolution of the porous media
Formulamos um modelo simplificado para o estudo do processo de injeção de solvente em reservatórios de petróleo, onde o fluido injetado (um ácido) tem a capacidade de dissolver parcialmente a matriz sólida. Como hipóteses principais, consideramos que o solvente e o soluto (componente químico que constitui o meio poroso) são espécies totalmente misc

15. Novos esquemas centrais de diferenças finitas para a simulação de escoamentos multifásicos em reservatórios de petróleo / New finite-difference central schemes applied to multiphase flows in petroleum reservoirs
Os escoamentos bifásicos incompressíveis água-óleo são modelados por um sistema de equações diferenciais parciais nas incógnitas velocidade, pressão e saturação. Neste trabalho é apresentado um novo método numérico em duas dimensões espaciais para a resolução numérica da equação de transporte de massa. Suas principais características sã

16. Modelos de depleção para reservatorios de oleo espumo / Depletion models for foamy oil reservoirs
Fields in Canada and Venezuela, which contain foamy oil reservoirs, have exhibited a primary oil recovery on the order of 10 to 15 % greater than the recovery estimated by black-oil simulators. Besides the high oil recovery, other unusual characteristics have been observed, as low gas-oil ratio and high reservoir pressure maintenance. Such discrepancy betwee

17. TÃcnicas de otimizaÃÃo da produÃÃo para reservatÃrios de petrÃleo: abordagens sem uso de derivadas para alocaÃÃo dinÃmica das vazÃes de produÃÃo e injeÃÃo
Petroleum Engineering daily activities are faced with a series of situations that call for optimal solutions in dierent contexts. At all phases of Oil &Gas industryâs workflow, it is possible to find out problems which need optimization, in larger or smaller scale, with more or less complexity. In reservoir engineering, there exists great in

18. Injection of the tracers in petroleum reservoir: multiscale modeling and numerical simulation / Injeção de traçadores em reservatórios de petróleo: modelagem multi-escala e simulação numérica
The spatial variations in porous media (aquifers and petroleum reservoirs) occur at all length scales (from the pore scale to the reservoir scale) and are incorporated in the governing equations for multiphase flow problems on the basis of random fields (geostatistical models). As a consequence, the velocity field is a random function of space. The randomnes

19. Use of quality maps in reservoir management
The definition and management of a production strategy for petroleum fields is one of the most important tasks in reservoir engineering. It is a complex process due to the high number of parameters, operational restrictions and objectives involved, and due to uncertainties in geological and economic scenarios. This work shows an important tool to improve the

20. Influencia de restrições operacionais na definição das estrategias de produção
Production strategies for petroleum fields are chosen with the objective of achieving the best possible performance of the reservoir, considering physical, operational and economical constraints. In many published papers regarding production strategy optimization, only the reservoir is considered, simplifying the analysis process by not considering the opera

21. SISTEMA INTELIGENTE DE OTIMIZAÇÃO DE ALTERNATIVAS DE DESENVOLVIMENTO DE CAMPOS PETROLÍFEROS / INTELLIGENT SYSTEM FOR OPTIMIZATION OF ALTERNATIVES FOR PETROLEUM FIELDS DEVELOPMENT
This work investigates the problem of optimization of alternatives for petroleum fields` development. A development alternative refers to the way a well-known and delimited petroleum field is placed in production. This process involves the determination of the number, localization and scheduling of producer and injector wells. Thus, the optimization of alter

22. Sistemas de automação e supervisão do laboratório de avaliação dos processos de medição de vazão e BSW
During a petroleum well production process, It is common the slmultaneous oil and water production, in proportion that can vary from 0% up to values close to 100% of water. Moreover, the production flows can vary a lot, depending on the charaeteristies of eaeh reservoir. Thus being, the meters used in field for the flow and BSW (water in the oil) measurement

23. Metodologia para o desenvolvimento de campos de petroleo
The main scope of this work is to study and develop a methodology which allows the elaboration of project for oilfield development. Therefore it is necessary to consider the integration of the human, technological and economical issues that are important parameters in the engineering project. The spiral concept was applied for the project in order to coordin

24. Comportamento da temperatura do fluido infetado no reservatorio em operações de aciclificação de matriz
Matrix Acidization is frequently used to remove formation damage from pore plugging caused by deposition of small mineral particles. The kinetics of the chemical reactions between acid and minerais is very sensitive to fluid temperature. The temperature of the acid at the injection zone depth depends on the heat transfer that occurs as the acid travels throu
