Abstract:
A bridge plug for a well includes an actuator member that moves from a first position such that the bridge plug is in a retracted position and a second position such that the bridge plug is in a deployed position. The bridge plug includes a slip section comprising one or more slips that grip a surface radially outward of the bridge plug in the deployed position and a petal section positioned downward of and adjacent to the slip section, the petal section comprising a plurality of petals that fan radially outward from the bridge plug in the deployed position to catch a slurry. The bridge plug also includes a centralizer section positioned downward of and adjacent to the pedal section, the centralizer section having a plurality of centralizers that ramp outwardly in an upward direction in the deployed position for centralizing the bridge plug.
