Efeito da contaminação por salmoura nas propriedades de fluido de perfuração aquoso
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia do Petróleo, 2016-11-30)
Simulação numérica do escoamento particulado para o preenchimento de canal fraturado
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2013-06-21)
During the drilling process, the fluid loss to formation is one of the most important players that affect the productivity of the well. When combined with high pressure gradients at the wellbore-reservoir interface, fractures ...
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 ...
Simulação numérica do escoamento de fluido de lei de potência com partículas para o preenchimento de fraturas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em Engenharia MecânicaUTFPR, 2019-12-06)
The invasion of drilling fluid from the annular region into the formation during the drilling an oil well is known as lost circulation. Besides the cost related to fluid replacement, there is a possibility of damaging the ...
Modelagem e otimização de manobras em processos de perfuração de poços de petróleo e gás
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-04-06)
The control of pressure gradients generated by drilling string's movements during tripping operations is a great challenge to be overcome. High axial velocities imposed on the drill string can generate sufficiently large ...
