1. Análise do modelo de mistura aplicado em escoamentos isotérmicos gás-líquido / Analysis of mixture model applied in gas-liquid isothermals flows
Gas-liquid flows are often found in nature as well as in various industrial applications. In the oil production, for example, in natural or artificial lift systems (continuous or intermittent gas-lift), gas and oil flow simultaneously in pipes. The prediction of gas-liquid behavior becomes necessary for technical and economic viability of many industrial pro

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

4. AN ANALYSIS OF THE DROP BREAKUP PROCESS IN AN OIL IN WATER EMULSION FLOWING TETWEEN PARALLEL DISKS / ANÁLISE DO PROCESSO DE QUEBRA DE GOTAS DE UMA EMULSÃO ÓLEO-ÁGUA NO ESCOAMENTO ENTRE DISCOS PARALELOS
Oil production is usually associated with the production of water, which may be found as a continuous phase or as a dispersed phase, in emulsions. Emulsions may be found in almost all the production stages: in reservoirs, production wells, production facilities, pipelines, in processing and in storage. The Electric Submersible Pump (ESP) is one of the method

5. Sistema especialista fuzzy para dimensionamento de bombeio mecânico
Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the

9. Modelagem do escoamento monofásico em bomba centrífuga submersa operando com fluidos viscosos / On the influence of viscosity upon electrical submersible pumping performance
In the oil industry, when artificial lift using Electrical Submersible Pumps (ESP) is considered, there is a need to determine their performance for displacing oils of medium to high viscosity. This work proposes a model that is able to predict the performance of conventional centrifugal pumps and ESPs when pumping heavier oils (meaning oils of high viscosit

10. 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
