CA 2674268

Moveable and split packer cups for use above a conventional coiled tubing fracturing or stimulation tool are described as well as methods for running these tools into a wellbore. These devices can be used for extended stimulation intervals with coiled tubing, as well as for a secondary pressure containment to avoid pressure communication with uphole formations or perforations.

L'invention concerne des coupelles de garniture mobiles et fractionnées destinées à être utilisées au-dessus d'un outil conventionnel de fracturation ou de stimulation sur tubage enroulé, ainsi que des procédés pour faire passer ces outils dans un puits de forage. Ces dispositifs peuvent être utilisés pour des intervalles stimulation étendus sur tubage enroulé, ainsi que pour un confinement en pression secondaire pour éviter la communication en pression avec des formations ou des perforations situées plus haut dans le trou.
