Abstract

A frac plug with a flapper, wherein the flapper is configured to set and unset based on a pressure differential and/or fluid flow associated with the frac plug.

Claims (21)

1. A method for utilizing a frac plug, the method comprising:

positioning a blocking device across a central axis of the frac plug;

increasing a pressure above the frac plug to a first pressure;

increasing the pressure above the frac plug to a second pressure;

removing a component from a passageway responsive to the pressure above the frac plug increasing to the second pressure, wherein the second pressure is greater than the first pressure, wherein when the component is removed from the passageway, fluid can flow through an inner mandrel of the frac plug.

2. The method of claim 1 , further comprising:

flowing the fluid from a distal end of the frac plug to a proximal end of the frac plug through the passageway.

3. The method of claim 1 , wherein the second pressure is less or equal to a pressure rating of the frac plug.

4. The method of claim 1 , further comprising:

flowing fluid from a distal end of the frac plug to a proximal end of the frac plug.

5. The method of claim 1 , wherein the blocking device is formed of at least one of a dissolvable material, composite material or cast iron.

6. A system for a fracturing operation, the system comprising:

a frac plug;

a blocking device configured to extend across a central axis of the frac plug;

a pressure above the frac plug that is increased to a first pressure to perform the fracturing operation;

a removeable component configured to be removed from a passageway responsive to increasing a pressure within the frac plug to a second pressure, wherein the second pressure is greater than the first pressure.

7. The system of claim 6 , wherein when the component is removed from the passageway, fluid can flow through an inner mandrel of the frac plug.

8. The system of claim 7 , wherein the fluid is configured to flow from a distal end of the frac plug to a proximal end of the frac plug through the passageway.

9. The system of claim 6 , wherein the second pressure is less or equal to a pressure rating of the frac plug.

10. The system of claim 6 , wherein the blocking device forms a seal across the central axis of the frac plug when the frac plug is being run in hole.

11. The system of claim 6 , wherein the blocking device is comprised of at least one of a dissolvable material, composite material or cast iron.
