13. Analysis of the rheological behavior of cement pastes containing tire residues for oil wells / Análise do comportamento reológico de pastas de cimento contendo resíduos de pneu para poços de petróleo
The low tenacity presented by the Portland cement pastes used in the oil wells cementation has been motivating several researches with attention focused on alternative materials. Additives have been developed to generate flexible pastes with mechanical resistance capable to support the expansions and retractions of the metallic covering of the wells that sub

14. Estudo experimental sobre recuperação de oleo pesado atraves da combustão in-situ / Experimental study of heavy oil recovery through in-situ combustion
Este trabalho foca a recuperação melhorada de petróleo através da técnica conhecida como combustão in-situ. Ensaios experimentais foram realizados com óleo pesado de 12,8ºAPI procedente de um campo onshore no Brasil a fim de avaliar a influência da argila no meio poroso com saturações iniciais de óleo variando de 25 a 50%. O aparato experimental

15. Estudo paramétrico da recuperação de petróleo pesado por aquecimento eletromagnético resistivo / Estudo paramétrico da recuperação de petróleo pesado por aquecimento eletromagnético resistivo
O Aquecimento Elétrico Resistivo (AER) é um método térmico usado para aumentar a recuperação de petróleo. Este aumenta a vazão de óleo e conseqüentemente a recuperação de petróleo devido ao aumento de temperatura promovida pela passagem de corrente elétrica na zona de interesse. O AER tem algumas vantagens sobre métodos térmicos conhecidos, c

16. Estudo da recuperação de óleo por drenagem gravitacional assistida por injeção de vapor
Steam assisted gravity drainage process (SAGD) involves two parallel horizontal wells located in a same vertical plane, where the top well is used as steam injector and the bottom well as producer. The dominant force in this process is gravitational. This improved oil recovery method has been demonstrated to be economically viable in commercial projects of o

17. Modelagem e previsão de comportamento de processos de injeção de vapor em escalas de laboratorio / Modeling and prediction behavior of steam injection process on laboratory scales
Steam injection is one of the most widely used techniques in the word for heavy oil recovery. The scope of this work refers to the proposition of an experimental apparatus for studying this technique. The apparatus is detailed, with emphasis on its major components, such as: steam generator, steam quality control and the injection prototypes: a tube to study

18. Modelagem e simulação do processo de separação de oleo de soja-hexano por evaporação
Until the two first decades of century XX, the industrial extraction of oleaginosas were carried out exclusively by mechanical process. This process allow to extracted oil of very good quality, but it leads the left residues in the solid material (pie) to be very high, for example 5% for grains as of soy. Such residues besides implying in loss of oil, affect

19. Otimização energetica de redes de trocadores de calor industriais : aplicações em engenharias de petroleo, alimentos e quimica
This work deals with the industrial process analysis, includingvarious types and sizes, looking for their optimization fiom the economic and energetic point of view. Not only a single point of optimality was searched but a set of options which could permit to a decision maker to choose the best situation in each case. ln the development of this study were ut

20. Sintese, caracterização e algumas propriedades do oxido de tetanio (IV) enxertado sobre superficie de silica gel
The synthesis of titanium(IV) oxide on silica gel surface was carried out reacting the silanol groups of the silica gel surface with titanium tetrachloride, in organic solvent. The reproducibility of the method was very satisfactory for the different silicas, always resulting in an average quantity of titanium of 1.5 mmol g. The X-ray photoelectron spectrosc

21. Injeção de vapor em reservatorios heterogeneos com dupla porosidade
Steam injection is the most used enhanced oil recovery method nowadays. Its étplication has gained wide acceptance even in the case of naturally fractured reservoirs. ln this work, was developed a thermal numerical simulator for oil reservoirs with radial or linear flux geometries. The equations that control oil, gas, water and energy were studied, as well
