Abstract
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.
