Methods and systems for a frac sleeve
A frac sleeve with an expandable ball seat. More specifically, the systems and methods include a hydraulically sliding frac sleeve with a moving screen, check valve or flapper that is configured to be align with a fixed production port positioned on an outer sidewall.
1. A frac sleeve comprising:
an inner sleeve configured to move relative to a fixed outer sidewall;
an inner frac port positioned through a circumference of the inner sleeve;
a screen or one way valve positioned through the circumference of the inner sleeve, the screen or one way valve and the inner frac port being offset from each other;
an outer production port positioned through the fixed outer sidewall, the outer production port configured to be aligned with the inner frac port in a first mode when a pressure within a central bore is greater than a first threshold and the screen or one way valve in a second mode when the pressure within the central bore is less than or equal to the first threshold;
a seat configured to selectively secure an object in place to control the pressure within central bore,
a recess configured to receive the seat responsive to decreasing the pressure within the central bore when the seat that selectively secures the object is aligned with the recess, the recess being an indentation within the outer sidewall extending from an inner circumference of the outer sidewall towards an outer circumference of the outer sidewall.
2. The frac sleeve of claim 1 , wherein the screen or one way valve is positioned more proximate to a distal end of the inner sleeve than the inner frac port.
3. The frac sleeve of claim 1 , wherein the screen or one way valve is positioned more proximate to a proximal end of the inner sleeve than the inner frac port.
4. The frac sleeve of claim 1 , further comprising:
an adjustable member that is configured to compress and elongate.
5. The frac sleeve of claim 4 , wherein in the first mode the adjustable member is compressed, and in the second mode the adjustable member is elongated.
6. The frac sleeve of claim 1 , wherein the screen or one way valve is configured to filter materials entering the frac sleeve through the outer production port.
7. The frac sleeve of claim 1 ,
wherein the recess is positioned below the outer production port, wherein the seat is configured to be aligned with the recess after the pressure within the central bore is increased to be greater than the first threshold followed by decreasing the pressure within the central bore to be less than or equal to the first threshold.
8. The frac sleeve of claim 1 , wherein in the second mode the screen or one way valve is configured to be positioned directly adjacent to the outer production port.
9. The frac sleeve of claim 1 , wherein in the first mode the screen or one way valve is misaligned with the outer production port.
10. The frac sleeve of claim 1 , wherein the screen or one way valve is configured to be aligned with the outer frac port during a production stage of a wellbore.
11. A method utilizing a frac sleeve comprising:
sliding an inner sleeve relative to a fixed outer sidewall, the inner sleeve including an inner frac port positioned through a circumference of the inner sleeve, and a screen or one way valve positioned through the circumference of the inner sleeve, the screen or one way valve and the inner frac port being offset from each other, the fixed outer sidewall including an outer production port positioned through the fixed outer sidewall;
increasing a pressure within a central bore;
aligning the outer production port with the inner frac port in a first mode when the pressure within the central bore is greater than a first threshold;
decreasing the pressure within the central bore;
selectively securing an object in place on a seat to control the pressure within the central bore;
positioning the seat within a recess responsive to decreasing the pressure within the central bore when the seat that selectively secures the object is aligned with the recess, the recess being an indentation within the outer sidewall extending from an inner circumference of the outer sidewall towards an outer circumference of the outer sidewall; and
aligning the outer production port with the screen or one way valve in a second mode when the pressure within the central bore is less or equal to the first threshold.
12. The method of claim 11 , wherein the screen or one way valve is positioned more proximate to a distal end of the inner sleeve than the inner frac port.
13. The method of claim 11 , wherein the screen or one way valve is positioned more proximate to a proximal end of the inner sleeve than the inner frac port.
14. The method of claim 11 , further comprising:
compressing or elongating an adjustable member based on the pressure within the frac sleeve.
15. The method of claim 14 , wherein in the first mode the adjustable member is compressed, and in the second mode the adjustable member is elongated.
16. The method of claim 11 , further comprising:
filtering, via the screen or one way valve, materials entering the frac sleeve through the outer production port.
17. The method of claim 11 ,
wherein the recess is positioned below the outer production port, wherein the seat is configured to be aligned with the recess after the increasing and the decreasing pressure within the central bore.
18. The method of claim 11 , wherein in the second mode the screen or one way valve is configured to be positioned directly adjacent to the outer production port.
19. The method of claim 11 , wherein in the first mode the screen or one way valve is misaligned with the outer production port.
20. The method of claim 11 , wherein the screen or one way valve is configured to be aligned with the outer frac port during a production stage of a wellbore.
