Abstract:
A plug includes a tubular conduit having a first end and a second end. The plug also includes a cap disposed over the first end of the tubular conduit and coupled thereto. The cap is configured to mate with a wireline adapter kit of a perforating string. The plug additionally includes a guide shoe disposed over the second end of the tubular conduit and coupled thereto. The guide shoe is configured to move along the tubular conduit from an unset position, away from cap, to a set position, toward the cap. A gripping assembly is disposed around the tubular conduit between the cap and the guide shoe and coupled to the guide shoe. A sealing assembly is disposed between the cap and the gripping assembly. The sealing assembly includes a first sealing band and a second sealing band. The first sealing band is disposed around the tubular conduit and has an annular lip.
