Abstract

A frac sleeve with a set of inner sleeves that allow selective opening and closing of such sleeves.

Claims (40)

1. A frac sleeve comprising:

a plurality of frac sleeves run in hole, each of the plurality of frac sleeves being configured to treat a different zone within the well and including;

an outer sidewall with an outer sidewall port,

a first sleeve with a first active port,

a second sleeve with a second active port,

wherein the first active port moves in a first direction to be aligned with the second active port, and the second active port moves in a second direction to be aligned with the first active port, the first direction and second direction being opposite directions, wherein movement of the first sleeve to align the first active port and the outer sidewall port is independent from movement of the second sleeve, and the movement of the second sleeve is independent from the movement of the first sleeve, wherein the second sleeve remains static during the movement of the first sleeve to align the first active port and the outer sidewall port; and

an object configured to form a seal within each of the plurality of frac sleeves, the object being configured to be acted on by fluid pressure to align the first active port and the second active port within each of the plurality of frac sleeves.

2. The frac sleeve of claim 1 , wherein the first active port is configured to be misaligned with the outer sidewall port and the second active port before moving the first sleeve.

3. The frac sleeve of claim 2 , wherein a passageway is formed through the first active port, second active port, and outer sidewall after moving the first sleeve in the first direction and the second sleeve in the second direction, the passageway extending from an inner diameter of the frac sleeve to an annulus positioned outside of the frac sleeve.

4. The frac sleeve of claim 2 , wherein portions of the first sleeve are configured to overlap with portions of the second sleeve.

5. The frac sleeve of claim 1 , wherein the first sleeve includes a first proximal end and a first distal end, and the second sleeve includes a second proximal end and a second distal end, wherein the first distal end is configured to be positioned between the second proximal end and the second distal end.

6. The frac sleeve of claim 5 , further comprising:

a hydraulic vent having a variable size being positioned between the proximal end of the second sleeve and the proximal end of the first sleeve.

7. The frac sleeve of claim 1 , wherein the outer sidewall port is a frac port.

8. The frac sleeve of claim 1 , wherein the outer sidewall port is a production port.

9. The frac sleeve of claim 1 , wherein the first sleeve and the second sleeve are configured to be locked in place when the first active port and the second active port are aligned.

10. A frac sleeve system comprising:

a plurality of frac sleeves run in hole, each of the frac sleeves being configured to treat a different zone within the well and including;

an outer sidewall with an outer sidewall port,

a first sleeve with a first active port,

a second sleeve with a second active port, wherein the first sleeve includes a first proximal end and a first distal end, and the second sleeve includes a second proximal end and a second distal end, wherein the first distal end is configured to be positioned between the second proximal end and the second distal end, wherein in a first position the first distal end is positioned above the second active port, and

an object configured to form a seal within each of the plurality of frac sleeves, the object being configured to be acted on by fluid pressure to align the first active port and the second active port within each of the plurality of frac sleeves, wherein in a second position the first active port is aligned with the outer sidewall port and the second active port.

11. A method utilizing a frac sleeve system comprising:

running a plurality of frac sleeves in hole, each of the plurality of sleeves being configured to treat a different zone within the well and including a first sleeve and a second sleeve;

moving the first sleeve associated with a targeted sleeve of the plurality of sleeves with a first active port in a first direction;

moving the second sleeve associated with the targeted sleeve with a second active port in a second direction;

forming a seal, via an object, within each of the plurality of frac sleeves including the targeted sleeve;

aligning the first active port associated with the targeted sleeve and the second active port associated with the targeted sleeve based on fluid pressure being applied against the object forming the seal and moving the first sleeve associated with the targeted sleeve in the first direction and the second sleeve associated with the targeted sleeve in the second direction, wherein the first direction and the second direction are opposite directions, wherein movement of the first sleeve associated with the targeted sleeve to align the first active port and the outer sidewall port is independent from movement of the second sleeve associated with the targeted sleeve, and the movement of the second sleeve associated with the targeted sleeve is independent from the movement of the first sleeve associated with the targeted sleeve, wherein the second sleeve associated with the targeted sleeve remains static during the movement of the first sleeve associated with the targeted sleeve to align the first active port and the outer sidewall port.

12. The method of claim 11 , wherein the first active port is misaligned with the outer sidewall port and the second active port before moving the first sleeve associated with the targeted sleeve.

13. The method of claim 12 , further comprising:

forming a passageway through the first active port, second active port, and outer sidewall after moving the first sleeve associated with the targeted sleeve in the first direction and the second sleeve associated with the targeted sleeve in the second direction, the passageway extending from an inner diameter of the frac sleeve to an annulus positioned outside of the targeted frac sleeve.

14. The method of claim 12 , wherein portions of the first sleeve associated with the targeted sleeve are configured to overlap with portions of the second sleeve associated with the targeted sleeve.

15. The method of claim 11 , wherein the first sleeve associated with the targeted sleeve includes a first proximal end and a first distal end, and the second sleeve associated with the targeted sleeve includes a second proximal end and a second distal end, and

positioning the first distal end between the second proximal end and the second distal end.

16. The method of claim 15 , further comprising:

changing a size of a hydraulic vent, the hydraulic vent being positioned between the proximal end of the second sleeve associated with the targeted sleeve and the proximal end of the first sleeve associated with the targeted sleeve.

17. The method of claim 11 , wherein the outer sidewall port is a frac port.

18. The method of claim 11 , wherein the outer sidewall port is a production port.

19. The method of claim 11 , further comprising:

locking the first sleeve associated with the targeted sleeve and the second sleeve associated with the targeted sleeve in place after aligning with the outer sidewall port, first active port, and the second active port.
