Abstract

Provided is a latch coupling, a well system, and a method for forming a well system. The latch coupling, in one aspect, includes a housing having an outside diameter (OD) and an inside diameter (ID). The latch coupling, according to this aspect, further includes a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (W AS ) of each of the plurality of axial alignment slots is within 10% of each other.

Claims (33)

1. A latch coupling, comprising:

a housing having an outside diameter (OD) and an inside diameter (ID);

a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (W AS ) of each of the plurality of axial alignment slots is within 10% of each other;

an uphole radial extending latch collet selector profile located along the inside diameter (ID) of the housing uphole of the plurality of axial alignment slots; and

a downhole radial extending latch collet selector profile located along the inside diameter (ID) of the housing downhole of the plurality of axial alignment slots.

2. The latch coupling as recited in claim 1 , wherein the plurality of axial alignment slots is at least six axial alignment slots, and further wherein the width (W AS ) of each of the at least six axial alignment slots is within 10% of each other.

3. The latch coupling as recited in claim 1 , wherein the plurality of axial alignment slots is at least ten axial alignment slots, and further wherein the width (W AS ) of each of the at least ten axial alignment slots is within 10% of each other.

4. The latch coupling as recited in claim 1 , wherein the plurality of axial alignment slots is at least sixteen axial alignment slots, and further wherein the width (W AS ) of each of the at least sixteen axial alignment slots is within 10% of each other.

5. The latch coupling as recited in claim 1 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each extends 360 degrees around the housing.

6. The latch coupling as recited in claim 1 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each include tensile shoulders or compressive shoulders.

7. The latch coupling as recited in claim 1 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each include tensile shoulders and compressive shoulders.

8. The latch coupling as recited in claim 1 , wherein the plurality of axial alignment slots each have a length (L AS ), and further wherein the length (L AS ) is at least 3 times the width (W AS ).

9. A well system, comprising:

a wellbore extending through one or more subterranean formations; and

wellbore casing located in the wellbore, the wellbore casing including a latch coupling, the latch coupling including:

a housing having an outside diameter (OD) and an inside diameter (ID); and

a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (W AS ) of each of the plurality of axial alignment slots is within 10% of each other;

an uphole radial extending latch collet selector profile located along the inside diameter (ID) of the housing uphole of the plurality of axial alignment slots; and

a downhole radial extending latch collet selector profile located along the inside diameter (ID) of the housing downhole of the plurality of axial alignment slots.

10. The well system as recited in claim 9 , wherein the plurality of axial alignment slots is at least six axial alignment slots, and further wherein the width (W AS ) of each of the at least six axial alignment slots is within 10% of each other.

11. The well system as recited in claim 9 , wherein the plurality of axial alignment slots is at least ten axial alignment slots, and further wherein the width (W AS ) of each of the at least ten axial alignment slots is within 10% of each other.

12. The well system as recited in claim 9 , wherein the plurality of axial alignment slots is at least sixteen axial alignment slots, and further wherein the width (W AS ) of each of the at least sixteen axial alignment slots is within 10% of each other.

13. The well system as recited in claim 9 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each extends 360 degrees around the housing.

14. The well system as recited in claim 9 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each include tensile shoulders or compressive shoulders.

15. The well system as recited in claim 9 , wherein the uphole radial extending latch collet selector profile and the downhole radial extending latch collet selector profile each include tensile shoulders and compressive shoulders.

16. The well system as recited in claim 9 , wherein the plurality of axial alignment slots each have a length (L AS ), and further wherein the length (L AS ) is at least 3 times the width (W AS ).

17. A method for forming a well system, comprising:

forming a wellbore through one or more subterranean formations; and

positioning wellbore casing in the wellbore, the wellbore casing including a latch coupling, the latch coupling including:

a housing having an outside diameter (OD) and an inside diameter (ID); and

a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (W AS ) of each of the plurality of axial alignment slots is within 10% of each other;

an uphole radial extending latch collet selector profile located along the inside diameter (ID) of the housing uphole of the plurality of axial alignment slots; and

a downhole radial extending latch collet selector profile located along the inside diameter (ID) of the housing downhole of the plurality of axial alignment slots.
