1. Method for Cleaning Back-Produced Water from Polymer Flooding Operations to Determine Polymer Molar Mass Using Size-Exclusion Chromatography
One of the methods used by the oil industry to increase production is to inject water, containing polymer, into the reservoir. The viscosity of the aqueous solution is primarily responsible for the efficiency of this method, and is achieved using polymers with high molar mass. However, polymer degradation can occur during pumping and fluid displacement in th

2. Nonlinear static analysis of a pile-supported wharf
Resumo O objetivo deste artigo é desenvolver uma análise estática não-linear através de um estudo de caso de um cais sobre estacas situado em uma nova área portuária para petroleiras. A atividade sísmica da área é muito intensa com uma aceleração máxima do solo de 0.55 g. Por esta razão, é muito importante analisar o comportamento estrutural n

3. Lipopeptide production by Bacillus subtilis R1 and its possible applications
Abstract The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different temperatures and salt concentrations, where it produced

4. Guide for Recommended Practices to Perform Crack Tip Opening Displacement Tests in High Strength Low Alloy Steels
Abstract: Fracture mechanics approach is important for all mechanical and civil projects that might involve cracks in metallic materials, and especially for those using welding as a structural joining process. This methodology can enhance not only the design but also the service life of the structures being constructed. This paper includes detailed considera

5. 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

6. Desenvolvimento sustentável na Amazônia: uma nova abordagem do dendê com o aproveitamento da biomassa residual para a geração de energia. / Sustainable development in the Amazon region: a new approach with the use of palm oil biomass waste to generate energy
This study examines the viability of a sustainable project with the production of palm (Elaeis guineensis) to supply oil to food or cosmetic industries and the use of the residual biomass as a biofuel by a power plant. The biofuel side of the project aims the provision of electricity in part of the so called Isolated System, in southern Roraima. The analysis

7. Aplicação de ultrassons no deslocamento de petróleo em meio poroso / Ultrasound application to promote petroleum displacement in porous media
O objetivo desse trabalho foi avaliar o deslocamento de soluções de petróleo/diesel, em diferentes concentrações, observando o efeito das vibrações ultrassônicas no deslocamento dos fluidos presentes em meio poroso para obter um aumento na produção de petróleo. As bolhas formadas pelo ultrassom implodem na rocha de forma assimétrica, gerando jato

8. OBTENÇÃO E CARACTERIZAÇÃO DE EMULSÃO PARA CORREÇÃO DE ESCOAMENTO DE ÓLEO PESADO. / OBTAINING AND CHARACTERIZATION OF EMULSION FOR CORRECTION OF HEAVY OIL FLOW.
Extracting and producing heavy oil presents many difficulties, promoted by the nature of the constant quantities involved, such as viscosity of the oil, the means through where it moves the salinity of water, oil composition, the temperature and so forth. In the pumping, the amount of oil which is drawn is not enough to meet the expenses, that is, the cost-e

9. LIQUID-LIQUID DISPLACEMENT FLOWS IN A HELE-SHAW CELL INCLUDING NON-NEWTONIAN EFFECTS / DESLOCAMENTO DE LÍQUIDOS EM CÉLULA DE HELE-SHAW CONSIDERANDO EFEITOS NÃO NEWTONIANOS
This work studied the displacement of fluids in porous media using a Hele-Shaw cell. Specifically, was investigated experimentally the displacement of a non-Newtonian fluid by a Newtonian in a rectangular Hele-Shaw cell. The Saffman-Taylor or viscous fingering instability occurs when one fluid pushes a more viscous one, and a Hele-Shaw is a convenient tool t

10. Numerical model of oil spill as an environmental management method in contingency plan, applied to São Sebastião channel (SP). / Modelagem numérica do comportamento de derrames de óleo como método de gestão ambiental, em planos de contingência, aplicada ao canal de São Sebastião (SP).
The application of numeric models for analysis of oil spill in the coastal environments becomes one of the most important ways to understand the behavior of the oil in this case of impact, giving subsides to the prediction of the displacement of the patches and allowing best efficiency in the control of the extension of the impact agent. These assumptions gi

11. Estudo da segregação gravitacional do processo de injeção de vapor em reservátórios heterogêneos
Due to reservoirs complexity and significantly large reserves, heavy oil recovery has become one of the major oil industry challenges. Thus, thermal methods have been widely used as a strategic method to improve heavy oil recovery. These methods improve oil displacement through viscosity reduction, enabling oil production in fields which are not considered c

12. FLOW OF EMULSIONS IN POROUS MEDIA: EXPERIMENTS AND CAPILLARY NETWORK MODEL / ESCOAMENTO DE EMULSÕES EM MEIOS POROSOS: EXPERIMENTOS E MODELO DE REDE DE CAPILARES
Objective: Transport of emulsions in porous media is relevant to several subsurface applications. Many enhanced oil recovery processes involve emulsion formation and their flow in some form. Modeling the flow of emulsion in porous media is extremely challenging. The available descriptions based on effective viscosity are not valid when the drop size is of th
