Entender o impacto dessas mudanças nas diferenças sísmicas contribui para o gerenciamento do reservatório. Todavia, os efeitos das mudanças de pressão e saturação podem produzir respostas similares ou até mesmo iguais, conduzindo a interpretações errôneas. Analisar tais efeitos em conjunto e separadamente pode evitar ambiguidades na interpretação da resposta sísmica 4D. A metodologia AVO 4D foi utilizada nesse trabalho para separar os efeitos da mudança de pressão e saturação de fluidos por meio da variação na resposta das diferenças sísmicas. O método foi aplicado em diferentes cenários de produção: i) mudança de pressão e saturação; ii) mudança de pressão; e iii) mudança de saturação. A analise dos resultados foi realizada em seções de diferenças sísmicas sintéticas geradas a partir de dados sísmicos, petrofísicos e de produção. A metodologia proposta por Landro (2001) foi aplicada com o intuito de determinar as variações de pressão e saturação de fluidos em cada cenário, por meio de calibração petrofísica das amostras de carbonato. Foi realizado ajuste teórico por meio das equações apresentadas por Landro (2001) e comparados ambos os resultados, em seções de mudança de pressão e/ou saturação de fluidos e mapas de amplitude RMS para o topo do reservatório / Abstract: The 4D seismic response may be impacted by changes in pressure and fluid saturation in the reservoir during production. Understanding these changes in seismic differences contribute to the management of the reservoir. However, the effects of pressure and saturation changes may have the same response, leading to erroneous interpretations. To analyze these effects together and separately can avoid ambiguities in the interpretation of 4D seismic response. The 4D AVO methodology used in this work was applied in order to separate the effects of changes in pressure and fluid saturation through variation in the response of seismic differences. The method was applied in different production scenarios: i) change in pressure and saturation, ii) change in pressure, and iii) change in saturation. The analysis of the results was performed on seismic differences synthetic sections generated from seismic data, petrophysical and production. The methodology proposed by Landro (2001) was applied in order to discriminate the variations of pressure and fluid saturation in each scenario, using calibration samples of carbonate petrophysics. Were adjusted by means of theoretical equations presented by Landro (2001) and compared both results in sections of pressure change and/or fluid saturation and RMS amplitude maps to the top of the reservoir / Mestrado / Reservatórios e Gestão / Mestre em Ciências e Engenharia de Petróleo

Chronic hypertension was induced in female albino rats. Amelioration by means of daily feeding of histidine and ascorbic acid, histidine and vitamin E, histidine and urease, vitamin E, urease and ammonium chloride was attempted. Blood pressures were determined under sodium pentathol anesthetic by the indirect method using the foot. Chronic hypertension was produced by two methods, (1) Injections of DCA. This method was found to give inconsistent results. Several modifications of this procedure were tried unsuccessfully. (2) The use of a choline deficient diet. This method proved to give consistent results in producing chronic hypertension. Vitamin E was the only substance found useful in ameliorating the experimental chronic hypertension. This amelioration resulted only in the presence of excess vitamin E. This fact was thought to give further evidence for the vasodilator properties of vitamin E. An hypothesis was advanced that DCA may inhibit the sympathetic nervous system, to sensitize the vascular responsiveness to pressor and depressor substances. / Science, Faculty of / Botany, Department of / Zoology, Department of / Graduate

The effects of dietary and hormonal factors upon the blood pressure of male Wistar rats were investigated. 1. Desoxycorticosterone acetate was found to increase the blood pressure in the presence of excess dietary salt. 2. Estrogen overdosage produced hypertension in rats. Castrate animals were more sensitive to the effects of estrogen. Estrogen overdosage aggravated experimental hypertension induced by nutritional choline deficiency. 3. A period of nutritional choline deficiency was followed by hypertension. Desoxycorticosterone accelerated the development of hypertension in choline deficient animals. 4. Hypertension developed in rats 2 months after a prolonged period of inanition. 5. Antihistamine was found to induce profound variations in the blood pressure of male rats. 6. Rats pre-treated with desoxycorticosterone acetate showed a greater pressor response to adrenaline than normal intact rats. 7. Desoxycorticosterone and antihistamine were found to facilitate the occurrence of the Trueta shunt. / Science, Faculty of / Botany, Department of / Zoology, Department of / Graduate
