Estudo da distância entre poços no processo de injeção contínua de vapor
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2016-05-06)
Some of the existing hydrocarbon reserves currently are comprised of heavy oils and due to its high viscosity, conventional methods are not able to move it until the well producer satisfactorily, leaving large volume of ...
Modelagem e simulação numérica de escoamento sólido-fluido sobre meio poroso heterogêneo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2016-03-18)
During oil well drilling commonly the drilling fluid pressure in the well is greater than the pressure within the formation, which may cause the flow towards the porous substrate, a phenomenon referred to as invasion. The ...
Modelagem do deslocamento de uma coluna de perfuração imersa em leito de cascalhos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-05-08)
Investment in new technologies for the exploration of oil reservoirs in challenging scenarios is growing in the oil and gas industry. One of the techniques that has been widely used for the construction of oil wells in ...
Avaliação experimental da transmissão de pressão em tubulações preenchidas por fluidos viscoplásticos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2017-02-23)
Drilling fluids exhibit a viscoplastic behavior, which is defined by a yield stress. If the stress imposed to the fluid does not surpass the yield stress, the material behaves like an elastic solid; if the yield stress is ...
Análise da aplicação de ejetores de superfície para o aumento de produção de poços de petróleo
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2017-06-30)
When the reservoir doesn’t have enough energy to raise the fluids to the surface or when its natural flow rate isn’t economically viable, artificial lift methods are required. Among these there are those that are called ...
Effects of fluid viscosity in liquid-solid flow pattern transition in horizontal pipelines
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-11-26)
Cuttings removal is a problem of significant concern in drilling operations since poor hole cleaning may lead to several operational problems, such as reducing bits life and stuck pipe. Different configurations may be ...
Aplicação de modelos deep learning na estimação de vazão de petróleo em poços offshore com sistema de bombeio centrífugo submerso
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2022-02-24)
The fluid flow measurement is a fundamental activity for the oil and gas industry.
The correct produced volumes mensuration provides a good reservoirs management,
reducing production losses, guiding plans of the production ...
Experimental evaluation of cuttings displacement by the drill bit-drill string assembly in a horizontal well
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-11-29)
Not only the oil production but also the well depths have been increasing over the years in Brazil. As a consequence, new techniques and technologies have been required by the industry in order to be able to extract the ...
Rheological and thermal characterization of the effects of high pressure and high temperature on the properties of water-based drilling fluids with xanthan gum
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-05-04)
The water-based drilling fluid with xanthan gum and limestone under high-pressure and hightemperature conditions is investigated in the following experimental study using an Anton Paar MCR 702TD rheometer with pressure ...
