A method of using a kit in an environment, the environment comprising:
- a subterranean wellbore having a casing installed therein;
- a plurality of perforations formed in the casing;
- a tubular string installed within the casing such that an annulus exists between the casing the tubular string;
- the kit comprising:
- a plurality of plugs, each plug sized to seat against one of the plurality of perforations and comprising an insert element positioned within a deformable sleeve, in which the sleeve is tubular and is open on opposed first and second ends of the sleeve, in which a maximum cross-sectional dimension of the insert element exceeds a maximum cross-sectional dimension of the sleeve when the sleeve is in a relaxed state;
- the method comprising:
- lowering the plurality of plugs into the annulus until at least one of the plugs seats on a corresponding one of the perforations.
