Abstract
A bridge plug includes 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. The bridge plug is actuatable from a run-in state to a deployed state, 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.
Claims19
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;
- a guide shoe operatively coupled to a downhole end of the mandrel;
- and
- one or more slip pins extending axially from the guide shoe and received within a corresponding one or more slots defined in the slip 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 mandrel is axially movable relative to the setting cone to seal or open a flow path through the bridge plug.

A method of operating a bridge plug, comprising:
- conveying the bridge plug downhole as coupled to a setting tool, the bridge plug including:
- 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;
- a guide shoe operatively coupled to a downhole end of the mandrel;
- and
- one or more slip pins extending axially from the guide shoe and received within a corresponding one or more slots defined in the slip ring;
- actuating the setting tool and thereby transitioning the bridge plug from a run-in state to a deployed state;
- and
- with the bridge plug in the deployed state, axially moving the mandrel relative to the setting cone between a first position, where a flow path through the bridge plug is sealed and prevents fluid flow through the bridge plug in a downhole direction, and a second position, where fluid flow through the bridge plug in an uphole direction is permitted.
