1. AVALIAÇÃO DA TENSÃO INTERFACIAL ENTRE PETRÓLEO PARAFÍNICO E SUPERFÍCIES COM RESINAS EPÓXI / EVALUATION INTERFACIAL TENSION BETWEEN PARAFFIN OIL AND SURFACES WITH EPOXY RESINS
Oil is a very complex chemical system, as for instance, the paraffinic type which was considered as a fluid to be evaluated in this scientific paper, trough the static interfacial tension with the surfaces of the API 5L grade B conduction pipe and the EPOXY and EPOXY M resins. The paraffinic oil produced in the 7-PIR-244D-AL well, which is located in the pro

3. 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

4. MODELLING THE RHEOLOGICAL BEHAVIOR OF PARAFFINIC OILS AT TEMPERATURES NEAR AND BELOW ITS FLUIDITY POINT / MODELAGEM DO COMPORTAMENTO REOLÓGICO DE ÓLEOS PARAFÍNICOS A TEMPERATURAS PRÓXIMAS E ABAIXO DE SEU PONTO DE FLUIDEZ
Neste trabalho é desenvolvido um modelo constitutivo para representar o comportamento reológico complexo apresentado pelos petróleos parafinicos, na faixa de temperaturas em que estes tendem a se solidificar, em virtude do aprisionamento da fase líquida na rede cristalina formada pela parafina que daí da solução. São considerados os efeitos de memór

5. Effects of Temperature and Crude Oil Composition on Petroleum Biodegradation
The biodegradability of seven different crude oils was found to be highly dependent on their composition and on incubation temperature. At 20 C lighter oils had greater abiotic losses and were more susceptible to biodegradation than heavier oils. These light crude oils, however, possessed toxic volatile components which evaporated only slowly and inhibited m
