Abstract

A toe sleeve that is configured to allow communication between an inner diameter of the tool and an annulus outside of the tool during a bleed off cycle, which occurs after testing the casing. To test the casing, pressure within the inner diameter of the tool may be increased, and during a bleed off cycle the pressure within the inner diameter of the tool may be reduced.

Claims (38)

1. A method associated with a toe sleeve comprising:

positioning a rupture disc within a sleeve port positioned through an inner sleeve;

equalizing pressure across the rupture disc in a first mode via an equalizing port, wherein in the first mode the sleeve port is misaligned with a sidewall port;

creating a pressure differential across the rupture disc in a second mode, wherein in the second mode the sleeve port is aligned with the sidewall port; and

forming a first piston area on a proximal end of the inner sleeve, the first piston area being a first total surface area impacting a downhole movement of the first sleeve;

forming a second piston area on a distal end of the inner sleeve, the second piston area being a second total surface area impacting an up hole movement of the second sleeve, the first piston area being larger than the second piston area.

2. The method of claim 1 , wherein the second piston area includes a first surface area and a second surface area, the first surface area and the second surface area being offset from each other.

3. The method of claim 2 , further comprising:

positioning a force generating device within a chamber, wherein the chamber is in communication with an inner diameter of the toe sleeve, a distal end of the force generating device being positioned between the first surface area and the second surface area.

4. The method of claim 3 , wherein a seal is positioned between the first surface area and the second surface area.

5. The method of claim 1 , further comprising:

positioning locking fingers associated with the inner sleeve adjacent to locking joints associated with the outer sidewall to limit the axial movement of the inner sleeve.

6. The method of claim 2 , further comprising:

aligning locking fingers associated with the inner sleeve and the first total surface area with a recess positioned in the outer sidewall to limit an impact of a piston area on a proximal end of the inner sleeve, the locking fingers being positioned on a proximal end of the inner sleeve.

7. The method of claim 6 , wherein the recess has a larger diameter than the proximal end of the sliding sleeve, and the locking fingers are configured to be positioned within the recess to limit the downhole movement of the inner sleeve.

8. The method of claim 1 , wherein the equalizing port extends through the inner sleeve.

9. The method of claim 1 , wherein a first surface of the rupture disc is configured to face a central axis, and a second face of the rupture disc is configured to face an inner circumference of the outer sidewall.

10. The method of claim 1 , further comprising:

positioning the inner sleeve port between seals in the second mode; and

positioning the inner sleeve port outside of the seals in the first mode.

11. A system associated with a toe sleeve comprising:

a rupture disc positioning within a sleeve port, wherein the sleeve port extends through a sliding sleeve;

an equalizing port extending through the sliding sleeve, the equalizing port being configured to equalize a pressure across the rupture disc in a first mode and allow for a pressure differential across the rupture disc in a second mode, wherein in the first mode the sleeve port is misaligned with a sidewall port, wherein in the second mode the sleeve port is aligned with the sidewall port;

a first piston area on a proximal end of the inner sleeve, the first piston area being a first total surface area impacting a downhole movement of the first sleeve;

a second piston area on a distal end of the inner sleeve, the second piston area being a second total surface area impacting an up hole movement of the second sleeve, the first piston area being larger than the second piston area.

12. The system of claim 11 , wherein the second piston area includes a first surface area and a second surface area, the first surface area and the second surface area being offset from each other.

13. The system of claim 12 , further comprising:

a force generating device within a chamber, the force generating device being configured to move the sliding sleeve, wherein the chamber is in communication with an inner diameter of the toe sleeve, a distal end of the force generating device being positioned between the first surface area and the second surface area.

14. The system of claim 13 , wherein a seal is positioned between the first surface area and the second surface area.

15. The system of claim 11 , further comprising:

locking fingers associated with the sliding sleeve configured to be positioned adjacent to locking joints associated with the outer sidewall to limit the axial movement of the sliding sleeve.

16. The system of claim 12 , further comprising:

a recess positioned in the outer sidewall, wherein locking fingers associated with the inner sleeve and the first total surface area are configured to move to be aligned with the recess to limit an impact of a piston area on a proximal end of the inner sleeve, the locking fingers being positioned on a proximal end of the inner sleeve.

17. The system of claim 16 , wherein the recess has a larger diameter than the proximal end of the sliding sleeve, and the locking fingers are configured to be positioned within the recess to limit the downhole movement of the inner sleeve.

18. The system of claim 11 , wherein the equalizing port extends through the sliding sleeve.

19. The system of claim 11 , wherein a first surface of the rupture disc is configured to face a central axis, and a second face of the rupture disc is configured to face an inner circumference of the outer sidewall.

20. The system of claim 11 , further comprising:

a pair of seals, wherein the sleeve port is configured to be positioned between the pair of seals in the second mode and outside of the pair of seals in the first mode.
