1. SYNTHESIS AND CHARACTERIZATION O F SODIUM METHYL ESTER SULFONATE FOR CHEMICALLY-ENHANCED OIL RECOVERY
Abstract Attention has been given to reduce the cost of surfactant by using castor oil as an alternative natural source of feedstock. A new surfactant, sodium methyl ester sulfonate (SMES) was synthesised using ricinoleic acid methyl ester, which is obtained from castor oil, for enhanced oil recovery in petroleum industries. The performance of SMES was studi

2. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

3. Investigation of asphaltene precipitation in miscible gas injection processes: experimental study and modeling
Asphaltene precipitation during natural depletion and miscible gas injection is a common problem in oilfields throughout the world. In this work, static precipitation tests are conducted to investigate the effects of pressure, temperature and gas type and concentration on asphaltene instability. Three different oil samples have been studied under reservoir c

4. Estudo do comportamento PVT de misturas de metano e fluidos de perfuração base éster / Study of the PVT behavior of methane and ester based drilling fluids mixtures
During conventional drilling operations, it is necessary to maintain the wellbore pressure greater than the reservoir pore pressure, otherwise a kick may occur. If the well control procedure is not effective during the circulation of the formation influx out of the well, a blowout could happen, which is a dangerous event concerning safety and environmental i

5. Development of natural gas fields under uncertainties / Desenvolvimento de campos de gas natural sob incertezas
This work studied the use of a methodology that allow calculate the risks and the value of information (VOI) in natural gas fields at initial stage of development. It is necessary to know the specific characteristics of recovery from a natural gas field, recognize uncertainties, both geological and the market and also the risks involved in investment decisio

6. NUMERICAL AND COMPUTATIONAL SIMULATION OF LOW DENSITY TURBIDITY CURRENTS FOR BASIN SEDIMENTATION / SIMULACAO NUMERICA E COMPUTACIONAL DE CORRENTES DETURBIDEZ DE BAIXA DENSIDADE PARA SEDIMENTACAO DE BACIAS
Turbidity currents occur in both natural and man-made situations. In agreement with some researchers, most of the world¿s oil reserves are stored in hydrocarbon reservoir built by turbidity systems. Because of the importance of these currents, this work proposes a consistent and efficient numerical method for simulations of turbidity currents for basin sedi

7. Development and implantation of an operational setup designed for the evaluation of new tracers for oil reservoir characterization / Desenvolvimento e inplantação de um sistema operacional para a qualificação do desempenho de novos traçadores para reservatórios de petróleo
Petroleum, nowadays, is one of the most important natural resources in the world, since it is one of the main primary sources of energy and also raw material for many different products. It can be found accumulated in the subsoil, and was produced from the remaining portions of animals and vegetables, in a process that took millions of years to be concluded.

8. Estudo integrado de análogo a reservatórios petrolíferos fluviais: caracterização, parametrização e modelagem tridimensional de depósitos recentes do Rio Assu (Rio Grande do Norte/Brasil)
This work shows a integrated study of modern analog to fluvial reservoirs of Açu Formation (Unit 3). The modern analog studied has been Assu River located in the same named city, Rio Grande do Norte State, Northeast of Brazil. It has been developed a new methodology to parameterizating the fluvial geological bodies by GPR profile (by central frequency anten

9. 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

10. MULTI-RESOLUTION FOR VISUALIZATION OF NATURAL OIL RESERVOIRS / MULTI-RESOLUÇÃO PARA A VISUALIZAÇÃO DE RESERVATÓRIOS NATURAIS DE PETRÓLEO
Current flow-simulation meshes of natural oil reservoirs (NOR) are composed of hundreds of thousands of hexahedral cells. The visualization of the geometry of these cells superimposed with color attributes to represent properties and flow results requires the rendering of an unstructured mesh of millions of triangles. Current graphics hardware does not allow

11. Caracterização dos fluidos H2S e agua em reservatorios carbonaticos
Reservoir fluids from two basins - Campos and Santos - of East Brazil margin have been studied. Samples from over 16 wells have been utilized in the fluid characterization. Water and hydrogen sulphide (H_) are fluids with large distribution in petroleum fields and may provide important informations for reservoir studies. High H2S concentratios are normally a

12. Analise do comportamento de reservatorios submetidos a segregação gravitacional usando pseudo-funções
The main purpose of this work is to study the behavior of a solution - gas reservoir under a gas-cap drive during natural depletion. The physical system consists of a two-dimensional cylindrical reservoir, with a well at the center, producing from its lower portion. We consider the flow of oi! and gas in the presence of gravitacional effects. Capillary effec
