Abstract
A bridge plug includes a mandrel, a setting cone disposed at least partially about the mandrel, and a slip ring and a sealing element disposed at least partially about the setting cone. A guide shoe is operatively coupled to a downhole end of the mandrel and the bridge plug is actuatable from a run-in state to a deployed state. When the bridge plug is in the deployed state, the mandrel is axially movable relative to the setting cone to seal or open a flow path through the bridge plug.
Claims20
A bridge plug, comprising:
- a mandrel;
- a setting cone disposed at least partially about the mandrel;
- a slip ring and a sealing element disposed at least partially about the setting cone;
- and
- a guide shoe operatively coupled to a downhole end of the mandrel,
- wherein the bridge plug is actuatable from a run-in state to a deployed state, and wherein, when the bridge plug is in the deployed state, the mandrel is axially movable relative to the setting cone to seal or open a flow path through the bridge plug.

A bridge plug, comprising:
- a slip ring;
- a setting cone extendable within the slip ring and having a frustoconical structure terminating at an uphole shoulder and an uphole extension extending from the uphole shoulder;
- a push ring arranged about the uphole extension;
- and
- a sealing element extending radially about the uphole extension and axially interposing the uphole shoulder and the push ring,
- wherein the bridge plug is actuatable from a run-in state to a deployed state, and wherein, when the bridge plug is in the deployed state, the push ring forces the setting cone into the slip ring to radially expand the slip ring and the push ring further forces the sealing element radially outward and into sealing engagement with an inner surface of casing.

A method, comprising:
- running a bridge plug into a wellbore as attached to a setting tool, the bridge plug including:
- a slip ring;
- a setting cone extendable within the slip ring and having a frustoconical structure terminating at an uphole shoulder and an uphole extension extending from the uphole shoulder;
- a push ring arranged about the uphole extension;
- and
- a sealing element extending radially about the uphole extension and axially interposing the uphole shoulder and the push ring;
- actuating the setting tool from a run-in state to a deployed state and thereby urging the push ring into engagement with the setting cone;
- radially expanding the slip ring as the setting cone advances into the slip ring and anchoring the slip ring against an inner wall of casing that lines the wellbore;
- and
- forcing the sealing element radially outward and into sealing engagement with an inner surface of the casing with the push ring.
