1. Extensión de durabilidad de pistones de bombas de fractura hidráulica mediante el empleo de tecnología de nitruración por plasma y PVD
ABSTRACT Hydraulic stimulation technique consists of "fracturing" the formation (rock reservoirs) through pumping a fracturing fluid downhole. This operation is performed by using hydraulic fracturing pumps. The pistons of these pumps are mechanical components performing the intake and compressing fracture fluid by reciprocating action. During this alternati

2. CHARACTERIZATION OF MATERIALS TO ENSURE THE CONDUCTIVITY OF HYDRAULICALLY INDUCED FRACTURES IN OIL WELLS AND GAS / CARACTERIZAÇÃO DE MATERIAIS PARA GARANTIR A CONDUTIVIDADE DE FRATURAS HIDRAULICAMENTE INDUZIDAS EM POÇOS DE PETRÓLEO E GÁS
Materials used as propant in hydraulic fracturing to improve production in oil wells must present properties that promote machanical stability of the fracture and sustain the flow of fluid from the reservoir through the fracture filled with the propant material. Due to diferent service conditions found in oil reservoirs, materials with different group of pro

3. LIQUID-LIQUID DISPLACEMENT FLOWS IN A HELE-SHAW CELL INCLUDING NON-NEWTONIAN EFFECTS / DESLOCAMENTO DE LÍQUIDOS EM CÉLULA DE HELE-SHAW CONSIDERANDO EFEITOS NÃO NEWTONIANOS
This work studied the displacement of fluids in porous media using a Hele-Shaw cell. Specifically, was investigated experimentally the displacement of a non-Newtonian fluid by a Newtonian in a rectangular Hele-Shaw cell. The Saffman-Taylor or viscous fingering instability occurs when one fluid pushes a more viscous one, and a Hele-Shaw is a convenient tool t

4. Mecanismos de recuperação de oleos pesados durante a injeção de vapor num reservatorio naturalmente fraturado / Heavy oil recovery mechanisms during steam injection in naturally fractured reservoirs
In this work, the individual and collective impacts of the mechanisms solution gas drive, CO2 generation, steam distillation, capillary imbibition and drainage gravitational, on the oil and gas recovery, were investigated during the steamflooding of a naturally fractured reservoir containing heavy oil. The investigation was performed for standard reservoir m

5. Estrategias de produção em reservatorios naturalmente fraturados / Recovery strategies for naturally fractured reservoirs
As características diferenciadas dos reservatórios naturalmente fraturados fazem com que o estudo e a previsão do comportamento desses reservatórios tenham-se convertido em temas de estudos freqüentes na indústria do petróleo. Nesse trabalho, apresenta-se um estudo que visa à formulação de regras gerais de escolha inicial de estratégias de produç

6. Caracterização macro, meso e microscópica das estruturas frágeis do corpo arenítico conglomerático da região de Santana do Acaraú (CE) e seu embasamento circundante
The structural framework of the sedimentary basins usually plays an important role in oil prospects and reservoirs. Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characteriz

7. 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
