Effects of drill cuttings discharge on meiofauna communities of a shelf break site in the southwest Atlantic
(SPRINGER, 2010)
The present study investigates the effects of drill cutting discharges on the structure of meiofauna communities in an area of the shelf break at Campos Basin, Southeast Brazil. Drilling activities were operated, in a first ...
Identification of lift-off mechanism failure for salt drill-in drilling fluid containing polymer filter cake through adsorption/desorption studies
(ELSEVIER SCIENCE BV, 2010)
Drilling fluid`s contact with the productive zone of horizontal or complex wells can reduce well productivity by fluid invasion in the borehole wall. Salted drilling drill-in fluid containing polymers has often been applied ...
Adsorção de tensoativo catiônico para organofilização de argila atapulgita
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2018-11-30)
The great challenges coming from well drilling, there was a need to develop or modify fluids whose properties were able to follow drilling requirement. Due this, the study with clays has been developed increasingly since ...

IMC Control of Oil Wells Pressure during Drilling Modeled as An Integrative Process with Time Delay
(2021-01-14)
Controlling the pressure of oil wells during drilling can be one of the most complex and dangerous processes operating stage. This study proposes the design of an internal model controller (IMC) to control the pressure at ...
Estudo da hidráulica de brocas de perfuração de poços - efeitos de parâmetros do processo de perfuração
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2013-09-18)
In this study it is performed a numerical analysis of oil drill bits hydraulics throughout computational fluid dynamics using the element-based finite volume method. The drilling fluid flow was evaluated after the fluid ...
