1. ANÁLISE EXPLORATÓRIA DAS CONCENTRAÇÕES DOS METAIS NA, CA, MG, SR E FE EM EXTRATO AQUOSO DE PETRÓLEO, DETERMINADOS POR ICP OES, APÓS OTIMIZAÇÃO EMPREGANDO PLANEJAMENTO DE EXPERIMENTOS
AbstractThe purpose of this study was to evaluate the best operating conditions of ICP OES for the determination of Na, Ca, Mg, Sr and Fe in aqueous extract of crude oil obtained after hot extraction with organic solvents (ASTM D 6470-99 modified). Thus, the full factorial design and central composite design were used to optimize the best conditions for the

2. Aceite de almendras dulces: extracción, caracterización y aplicación
The extraction of sweet almond oil at room temperature and reflux is an easy and accessible procedure to obtain natural oil in a laboratory scale for undergraduates' courses in chemistry and related areas. In this paper we show how the utilization of Fourier Transform Infrared (FTIR) spectroscopy can be interesting in the qualitative analysis of these oils.

3. Eosi: um modelo para desenvolvimento de sistemas embarcados tolerantes a falhas
The semiconductor technologies evolutions leads devices to be developed with higher processing capability. Thus, those components have been used widely in more fields. Many industrial environment such as: oils, mines, automotives and hospitals are frequently using those devices on theirs process. Those industries activities are direct related to environment

4. Aplicação de termogravimetria acoplada à espectrometria de massas para caracterização de petróleo e determinação da curva de evolução de gás sulfídrico
With the new discoveries of oil and gas, the exploration of fields in various geological basins, imports of other oils and the development of alternative fuels, more and more research labs have evaluated and characterized new types of petroleum and derivatives. Therefore the investment in new techniques and equipment in the samples analysis to determine thei

5. MODELO DE PROGRAMAÇÃO ESTOCÁSTICA PARA O PLANEJAMENTO ESTRATÉGICO DA CADEIA INTEGRADA DE PETRÓLEO / A STOCHASTIC PROGRAMMING MODEL FOR THE STRATEGIC PLANNING OF THE OIL SUPPLY CHAIN
The oil industry is one of the most important and dynamic in Brazil. As the oil industry naturally integrated, we need an appropriate strategic planning to the oil supply chain that consider all its processes, such as oil production, refining, distribution and refined products marketing. Moreover, the oil industry is susceptible to various uncertainties rega

6. Desenvolvimento de sistemas a base de tensoativos para recuperação avançada de petróleo
Petroleum is a complex combination of various classes of hydrocarbons, with paraffinic, naphtenic and aromatic compounds being those more commonly found in its composition. The recent changes in the world scenario, the large reserves of heavy oils and also the lack of new discoveries of large petroleum fields are indications that, in the near future, the oil

7. 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

8. Desenvolvimento de um simulador de bombeio por cavidades progressivas
The method of artificial lift of progressing cavity pump is very efficient in the production of oils with high viscosity and oils that carry a great amount of sand. This characteristic converted this lift method into the second most useful one in oil fields production. As it grows the number of its applications it also increases the necessity to dominate its

11. Escoamento trifasico vertical vertical de oleos pesados aplicado a elevação artificial / Theree-phase flow of heavy oil for application to artificial lift
The oil companies, by their Exploration and Production departments (E&P), have worldwide sought viable means of recovery and prQduction of heavy oil fields, so as to aggregate and delimit those reserves in order to provide the highest revenues. In this search, the role of elevation and flow is to supply an adequate transport for these oils through lines and
