1. Comportamento da corrosão microbiológica do aço duplex com aplicação de sais de quaternário de amônio
RESUMO A corrosão microbiológica tem causado diversos prejuízos para variados segmentos industriais que utilizam os materiais metálicos em seus sistemas. Uma forma de minimizar e até mesmo controlar os problemas causados pela corrosão microbiológica tem sido a aplicação de biocidas nestes sistemas. Neste trabalho, a corrosão microbiológica do aço

2. Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional
Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersib

3. Modificação do LLDPE através de silanos viabilizando a aplicação em camadas plásticas de linhas flexíveis / Study of silane grafting reactions of low density polyethylene for pipe applications
The flexible lines are flexible structures manufactured through plastic and steel layers that allows its use in order to permit fluid flow in exploration and production of hydrocarbon between offshore oil units and sea bed and/or coast. Nowadays these pipes are one of the main ways to permit the exploration of hydrocarbon in deepwater. The present study aims

4. The impact of the special participation fee in offshore fields using meta-modeling approach / O impacto da participação especial em campos de petroleo maritimos utilizando a meta-modelagem
The special participation fee is an important taxation mechanism for the government to appropriate a portion of the income originated from the exploration and production of petroleum/oil and natural gas, from fields with a great production or of great profitability. It was created from the Petroleum Law no. 9.478/97 that it established the government levies,

5. Electricity generation from the offshore wind energy source. / Geração de energia elétrica a partir da fonte eólica offshore.
In the last decade wind power source was the fastest-growing energy source. Technological learning curves for this sector fall down by a 15% a 20% rate each 3 years. Countries which are committed with wind power are running after the target of 12% wind into the worlds electrical production by 2020. The contribution of the offshore wind power (OWP) source is

6. Estudo experimental e numerico da dinamica de movimento de Riser em catenaria com escoamento interno / Experimental and numerical study of the motion dynamics of catenary riser considering internal flow
The pipe which transports fluids from the petroleum production well, on the seabed, up to the production unity, on the sea surface, is named riser. The main objective of this work is to characterize the dynamic response of a riser, hanging in catenary configuration, with the influence of the internal flow of hydrocarbons. It was observed from literature, tha

7. Estudo de reatores eletroquímicos para remoção de Cu2+ , Zn2+, Fenol e BTEX em água produzida
The production of water has become one of the most important wastes in the petroleum industry, specifically in the up stream segment. The treatment of this kind of effluents is complex and normally requires high costs. In this context, the electrochemical treatment emerges as an alternative methodology for treating the wastewaters. It employs electrochemical

8. AVALIAÇÃO DO IMPACTO ECONÔMICO DO DESENVOLVIMENTO DA PRODUÇÃO OFFSHORE / ANALYSIS OF THE ECONOMIC IMPACT OF THE OFFSHORE DEVELOPMENT
Alguns projetos típicos de explotação de petróleo em águas profundas no Brasil exigem que se adotem alternativas de menor custo de desenvolvimento para que possam ser viabilizados. Nesses casos, deve-se também buscar reduzir o tempo para o desenvolvimento da produção, incluindo a perfuração de poços, o sistema de coleta submarino e a instalação

9. Separação e captura do dióxido de carbono em instalações marítimas de produção de petróleo. / Carbon dioxide separation and capture in offshore petroleum production facilities.
The current Brazilian market needs to increase the natural gas supply to incentive the national scientific community to the challenge of developing new technologies routes aiming increase the utilization of the produced natural gas. Such challenge is followed by a world demand from signatory countries of the Kyoto Agreement (ratified in 2005) to reduce the g

12. Study of two-phase flow in moving risers for offshore petroleum production in deep waters / Estudo do escoamento bifasico em risers em movimento na produção maritima de petroleo em aguas profundas
The two-phase vertical flow is of utmost importance for petroleum production, since petroleum reservoirs produce oil and gas simultaneously, which must flow up to the undersea surface through wells, and from these to the production platform through vertical pipes (risers) in the sea. Throughout the flow, the mixture of oil and gas may develop several flow pa
