Abstract

Provided, in one aspect, is a ball seat release apparatus. The ball seat release apparatus, according to this embodiment, includes a shear sleeve having a recess pocket and a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position. The ball seat body further includes a longitudinal fluid passageway, a ball seat located in the longitudinal fluid passageway, one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat, and one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

First claim

What is claimed is:

1. A ball seat release apparatus, comprising:
a shear sleeve, the shear sleeve having a recess pocket located along a portion of an inner surface thereof, the shear sleeve further including a downhole shoulder configured to engage with a shoulder in a crossover sub the shear sleeve is configured to slide within; and
a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position in relation to the shear sleeve, and further wherein a shear feature releasably couples the ball seat body with the shear sleeve, the ball seat body including:
a longitudinal fluid passageway;
a ball seat located in the longitudinal fluid passageway;
one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat; and
one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

2. The ball seat release apparatus as recited in claim 1 , wherein the shear sleeve includes a locking snap feature.

3. The ball seat release apparatus as recited in claim 2 , wherein the recess pocket is a first recess pocket, and further wherein the ball seat body includes a second recess pocket located along a portion of an outer surface thereof, the locking snap feature configured to radially retract into the second recess pocket to lock the ball seat body and the shear sleeve relative to one another when the ball seat body is in the second linear position.

4. The ball seat release apparatus as recited in claim 2 , wherein the locking snap features is a snap ring.

5. The ball seat release apparatus as recited in claim 1 , wherein the recess pocket, one or more first fluid bypass ports, and one or more second fluid bypass ports are configured to provide a fluid flow path around a drop ball or plug engageable with the ball seat when the ball seat body is in the second linear position.

6. The ball seat release apparatus as recited in claim 5 , wherein a distance (D) between the one or more first fluid bypass ports and the one or more second fluid bypass ports is greater than a width (W) of the recess pocket.

7. The ball seat release apparatus as recited in claim 6 , wherein the ball seat body has a first outer diameter (d 1 ) proximate the one or more first fluid bypass ports and a second lesser outer diameter (d 2 ) proximate the one or more second fluid bypass ports.

8. The ball seat release apparatus as recited in claim 7 , wherein the one or more first fluid bypass ports do not radially align with the recess pocket when the ball seat body is in the first linear position, but the one or more second fluid bypass ports do radially align with the recess pocket when the ball seat body is in the first linear position, and the one or more first fluid bypass ports do radially align with the recess pocket when the ball seat body is in the second linear position, but the one or more second fluid bypass ports do not radially align with the recess pocket when the ball seat body is in the second linear position.

9. The ball seat release apparatus as recited in claim 1 , wherein the shear sleeve is a sliding sheer sleeve.

10. The ball seat release apparatus as recited in claim 1 , further including a first circumferential seal located between the sheer sleeve and the ball seat body proximate and uphole of the one more or more first fluid bypass ports, a second circumferential seal located between the sheer sleeve and the ball seat body proximate and downhole of the one more or more first fluid bypass ports, and a third circumferential seal located between the sheer sleeve and the ball seat body proximate and downhole of the one more or more second fluid bypass ports.

11. A well system, comprising:
a casing string secured within a wellbore extending through one or more subterranean formations;
a liner hanger and liner string suspended from and proximate a downhole end of the casing string; and
a ball seat release apparatus coupled proximate a downhole end of a running tool, and positioned within at least a portion of the liner hanger or liner string, the ball seat release apparatus including:
a shear sleeve, the shear sleeve having a recess pocket located along a portion of an inner surface thereof, the shear sleeve further including a downhole shoulder configured to engage with a shoulder in a crossover sub the shear sleeve is configured to slide within; and
a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position in relation to the shear sleeve, and further wherein a shear feature releasably couples the ball seat body with the shear sleeve, the ball seat body including:
a longitudinal fluid passageway;
a ball seat located in the longitudinal fluid passageway;
one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat; and
one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

12. The well system as recited in claim 11 , wherein the shear sleeve includes a locking snap feature.

13. The well system as recited in claim 12 , wherein the recess pocket is a first recess pocket, and further wherein the ball seat body includes a second recess pocket located along a portion of an outer surface thereof, the locking snap feature configured to radially retract into the second recess pocket to lock the ball seat body and the shear sleeve relative to one another when the ball seat body is in the second linear position.

14. The well system as recited in claim 11 , wherein the recess pocket, one or more first fluid bypass ports, and one or more second fluid bypass ports are configured to provide a fluid flow path around a drop ball or plug engageable with the ball seat when the ball seat body is in the second linear position.

15. The well system as recited in claim 14 , wherein a distance (D) between the one or more first fluid bypass ports and the one or more second fluid bypass ports is greater than a width (W) of the recess pocket.

16. The well system as recited in claim 15 , wherein the ball seat body has a first outer diameter (d 1 ) proximate the one or more first fluid bypass ports and a second lesser outer diameter (d 2 ) proximate the one or more second fluid bypass ports.

17. The well system as recited in claim 16 , wherein the one or more first fluid bypass ports do not radially align with the recess pocket when the ball seat body is in the first linear position, but the one or more second fluid bypass ports do radially align with the recess pocket when the ball seat body is in the first linear position, and the one or more first fluid bypass ports do radially align with the recess pocket when the ball seat body is in the second linear position, but the one or more second fluid bypass ports do not radially align with the recess pocket when the ball seat body is in the second linear position.

18. A method for completing a well system, comprising:
deploying a liner hanger and liner string within a casing string using a running tool
