The effect of PVA microfiber reinforcement on the mechanical and rheological behavior of class G oil well cement pastes
Nogueira Lima, Victor; Skadsem, Hans Joakim; Beltrán-Jiménez, Katherine; Velloso, Raquel Quadros; Silva, Flávio de Andrade (Peer reviewed; Journal article, 2023)During the life cycle of an oil well, the annular cement sheath will be exposed to load combinations that can result in failure. To enhance the structural integrity and ductility of the cement paste, and to improve the ... -
Triaxial behavior of a stabilized and a highly porous oil well cement paste at different saturation and drainage conditions
Lima, Victor Nogueira; Skadsem, Hans Joakim; Beltrán-Jiménez, Katherine; Zhemchuzhnikov, Alexandr; Velloso, Raquel Quadros; Silva, Flavio de Andrade (Peer reviewed; Journal article, 2022)Well cement is the most common barrier material in wells for geothermal and hydrocarbon production. As cements are exposed to hydrostatic loads and periods of deviatoric loading in wellbore environments, it is important ...
