  • Plug for a coiled tubing string
    Patent number: 11299957
    Abstract: A combination of a coiled tubing string, a tubing plug, and a setting tool is provided. The tubing plug has an inner mandrel with a movable, first stop toward a first end and a fixed second stop at a second end. As the first stop moves toward the second stop first and second seal ramps cause first and second elastomeric seals to seal against an inner surface of the coiled tubing string, and anchor ramps cause expandable anchors to expand and engage the inner surface of the coiled tubing string.
