Abstract

A system including a hanger system configured to support a tubular, including a hanger body with first and second axial sides, and an aperture extending between the first and second axial sides, wherein the hanger body is configured to receive the tubular through the aperture, a first retaining ring configured to couple to the tubular, and a first support ring configured to couple to the first axial side of the hanger body and radially energize the first retaining ring.

First claim

The invention claimed is:

1. A system, comprising:
a hanger system configured to mount in a bore of a surrounding tubular and support a tubular, wherein the hanger system comprises:
a hanger body with first and second axial sides, and an aperture extending between the first and second axial sides, wherein the hanger body is configured to receive the tubular through the aperture;
a first retaining ring configured to couple to the tubular; and
a first support ring configured to couple to the first axial side of the hanger body, wherein the first support ring is configured to move relative to the hanger body to actuate at least one angled interface to radially energize the first retaining ring about the tubular.

2. The system of claim 1 , wherein the hanger system comprises a first seal configured to couple to the tubular, wherein the first retaining ring and the first seal are disposed at least partially axially between the hanger body and the first support ring.

3. The system of claim 2 , wherein the hanger system comprises an energizing ring configured to radially energize the first seal and the first retaining ring, wherein the energizing ring is disposed at least partially axially between the hanger body and the first support ring.

4. The system of claim 3 , wherein the first support ring is configured to axially compress the energizing ring between the first support ring and the hanger body causing the at least one angled interface to radially compress the first support ring about the first seal and the first retaining ring.

5. The system of claim 3 , wherein the at least one angled interface comprises an angled interface between the hanger body and the energizing ring.

6. The system of claim 3 , wherein the at least one angled interface comprises an angled interface between the support ring and the energizing ring.

7. The system of claim 3 , wherein the at least one angled interface comprises an angled interface disposed on the first retaining ring, the first seal, or a combination thereof.

8. The system of claim 3 , wherein the energizing ring is disposed at least partially circumferentially about the first retaining ring and the first seal.

9. The system of claim 2 , comprising a bearing axially between the first seal and the first retaining ring, wherein the bearing is configured to enable the first seal and the first retaining ring to move independently in a radial direction relative to a central axis of the hanger system.

10. The system of claim 1 , wherein the hanger system comprises a second retaining ring configured to couple to the tubular and a second support ring configured to couple to the second axial side of the hanger body, and the second support ring is configured to radially energize the second retaining ring.

11. The system of claim 1 , comprising a mineral extraction system with the hanger system, wherein the mineral extraction system comprises the surrounding tubular configured to receive the hanger system and the tubular in the bore of the surrounding tubular.

12. The system of claim 1 , wherein the at least one angled interface comprises one or more angled interfaces disposed between the hanger body and the first support ring.

13. A system, comprising:
a hanger system configured to mount in a bore of a surrounding tubular and support a tubular, wherein the hanger system comprises:
a hanger body with first and second axial sides, and an aperture extending between the first and second axial sides, wherein the hanger body is configured to receive the tubular through the aperture;
a first retaining ring configured to couple to the tubular;
a first seal configured to couple to the tubular; and
a first support ring configured to couple to the first axial side of the hanger body, wherein the hanger system is configured to actuate at least one angled interface between the hanger body and the first support ring to radially energize the first retaining ring and the first seal about the tubular.

14. The system of claim 13 , wherein the hanger system comprises an energizing ring configured to radially energize the first seal and the first retaining ring about the tubular in response to actuation of the at least one angled interface.

15. The system of claim 14 , wherein the hanger system comprises a bearing axially between the first seal and the first retaining ring, wherein the bearing is configured to enable the first seal and the first retaining ring to move independently in a radial direction relative to a central axis of the hanger system.

16. The system of claim 14 , wherein the energizing ring is disposed at least partially circumferentially about the first retaining ring and the first seal.

17. The system of claim 13 , comprising a mineral extraction system with the hanger system, wherein the mineral extraction system comprises the surrounding tubular configured to receive the hanger system and the tubular in the bore of the surrounding tubular, wherein the surrounding tubular comprises a landing configured to support the hanger body.

18. The system of claim 17 , comprising one or more lock screws configured to axially compress the hanger body against the landing.

19. The system of claim 13 , wherein the at least one angled interface comprises an angled interface on at least one of the first retaining ring, the first seal, the hanger body, the first support ring, or a combination thereof.

20. The system of claim 19 , wherein the hanger system comprises a second retaining ring configured to couple to the tubular and a second support ring configured to couple to the second axial side of the hanger body, and the second support ring is configured to radially energize the second retaining ring.

21. The system of claim 13 , wherein the first retaining ring and the first seal are disposed at least partially axially between the hanger body and the first support ring.

22. A method, comprising:
actuating at least one angled interface between a hanger body and a first support ring of a hanger system to provide a radial actuation force; and
radially energizing a first seal and a first retaining ring of the hanger system about a tubular in response to the radial actuation force, wherein the hanger system is configured to mount in a bore of a surrounding tubular and support the tubular.

23. The method of claim 22 , wherein actuating the at least one angled interface comprises axial movement between the hanger body and the first support ring.

24. The method of claim 22 , comprising:
coupling the first support ring of the hanger system to a first portion of the hanger body;
coupling a second support ring of the hanger system to a second portion of the hanger body; and
coupling a second retaining ring of the hanger system to the tubular using axial movement of the second support ring.

25. The method of claim 22 , wherein actuating the at least one angled interface comprises actuating an angled interface disposed on at least one of the first retaining ring, the first seal, the hanger body, the first support ring, or a combination thereof.
