Simulação numérica da circulação direta e reversa em broca PDC na perfuração de poços de petróleo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2016-06-21)
The oil reserves are located hundreds of meters, or even kilometers, below the Earth’s surface. Nowadays, this natural resource exploration is made by the rotary drilling process, where a bit is used to build a well and ...
Caracterização experimental preliminar da formação de hidratos de metano com fluidos de perfuração na indústria de petróleo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2015-04-09)
Hydrates are crystalline solids composed of water molecules and molecules of gas or liquid (usually low molecular weight hydrocarbons). In the oil sector, with the growing demand for the exploration of increasingly deep ...
The viability of slim-hole drilling onshore Trinidad
(2018-09-10)
Abstract
Slim-hole drilling refers to the drilling of a well with a wellbore typically less than 7 in. in diameter. Slim-hole drilling is beneficial to the low-budget operator as there are considerable savings ...
Modelagem da propagação de pressão em fluidos de perfuração durante kick de gás
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2016-12-05)
In the process of drilling oil and gas wells the pressure control is an important task. If the pressure inside the well is smaller than the formation pressure, an influx of the formation may occur, phenomenon denominated ...
