- Abstract:
A technique facilitates utilization of a running tool system for use with a tubing hanger deployed at a wellhead. The running tool system may comprise a running tool which may be coupled to a hanger. The running tool may include a first sleeve which may be coupled to the hanger for moving the hanger in an axial direction. According to an embodiment, the running tool also may include a second sleeve which may be coupled to an adjustable landing ring disposed about the hanger. The second sleeve may be used to rotate the adjustable landing ring so as to lock the hanger in position.

- Claim:
1. A system, comprising: a running tool and hanger system, comprising: a running tool configured for coupling with a hanger, the running tool having: a first sleeve configured to couple to and move the hanger in an axial direction; and a second sleeve configured to couple to an adjustable landing ring surrounding the hanger, the second sleeve being configured to rotate the adjustable landing ring to drive a load ring in a radial direction to lock the hanger in position; and a hanger suspension system comprising one or more slips coupled to one or more pistons, wherein the one or more pistons are configured to drive the one or more slips against the hanger to couple to and suspend the hanger separate from the load ring.
- Claim:
2. The system as recited in claim 1 , wherein the running tool comprises a shear member configured to shear to enable the adjustable landing ring to slide under the load ring and drive the load ring in the radial direction to lock the hanger in position.
- Claim:
3. The system as recited in claim 1 , wherein the second sleeve is an outer sleeve relative to the first sleeve.
- Claim:
4. The system as recited in claim 1 , further comprising a support ring, wherein the load ring is supported between the adjustable landing ring and the support ring.
- Claim:
5. The system as recited in claim 4 , wherein the adjustable landing ring, the load ring, and the support ring are separate from the hanger suspension system.
- Claim:
6. The system as recited in claim 4 , wherein the support ring is releasably coupled to the adjustable landing ring by a shear member.
- Claim:
7. The system as recited in claim 1 , wherein the second sleeve is removably coupled to the adjustable landing ring via a castellated interface, the castellated interface comprises a castellation member disposed in a corresponding recess, the castellation member interfaces with the corresponding recess at a right angle edge to force rotation of the adjustable landing ring in response to rotation of the second sleeve in a first rotational direction, and the castellation member interfaces with the corresponding recess at a sloped edge to cause the castellation member to slide up and out of the corresponding recess in response to rotation of the second sleeve in a second rotational direction opposite from the first rotational direction.
- Claim:
8. The system as recited in claim 1 , wherein the hanger suspension system comprises a tubular housing having the one or more slips coupled to the one or more pistons, the running tool is configured to run the hanger into the tubular housing to enable the one or more slips to suspend the hanger followed by rotation of the second sleeve to rotate the adjustable landing ring to drive the load ring in the radial direction to lock the hanger in position in the tubular housing, and the running tool is retrievable from the tubular housing.
- Claim:
9. The system as recited in claim 1 , wherein the one or more pistons are hydraulically actuated in a radial inward direction to drive the one or more slips against the hanger.
- Claim:
10. A system for use in a well application, comprising: a hanger; and a running tool constructed for releasable engagement with the hanger, the running tool having an inner sleeve, coupled to the hanger during deployment of the hanger into a wellhead, and an outer sleeve which may be rotated relative to the hanger to force a load ring into engagement with the wellhead so as to support the hanger in the wellhead; and a hanger suspension system comprising one or more slips coupled to one or more pistons, wherein the one or more pistons are configured to drive the one or more slips against the hanger to couple to and suspend the hanger separate from the load ring.
- Claim:
11. The system as recited in claim 10 , wherein the load ring is forced into a profile located along an interior surface of a casing spool of the wellhead, and the one or more pistons are configured to move in a radial inward direction to drive the one or more slips against the hanger.
- Claim:
12. The system as recited in claim 10 , wherein the running tool comprises a shear member configured to shear to enable an adjustable landing ring to slide under the load ring and drive the load ring in the radial direction to lock the hanger in position, and hanger suspension system is separate from the adjustable landing ring and the load ring.
- Claim:
13. The system as recited in claim 10 , wherein the running tool further comprises an upper joint connected to the outer sleeve for rotation with the outer sleeve, wherein the combined upper joint and outer sleeve are initially coupled to the inner sleeve via a dog received in a recess.
- Claim:
14. The system as recited in claim 10 , wherein the load ring is forced into engagement with the wellhead via rotation of an adjustable landing ring which is threadably mounted on the hanger.
- Claim:
15. The system as recited in claim 14 , wherein the load ring is supported by a support ring initially coupled to the adjustable landing ring by a shear member.
- Claim:
16. The system as recited in claim 10 , wherein the outer sleeve is removably coupled to an adjustable landing ring via a castellated interface, the castellated interface comprises a castellation member disposed in a corresponding recess, the castellation member interfaces with the corresponding recess at a right angle edge to force rotation of the adjustable landing ring in response to rotation of the outer sleeve in a first rotational direction, and the castellation member interfaces with the corresponding recess at a sloped edge to cause the castellation member to slide up and out of the corresponding recess in response to rotation of the outer sleeve in a second rotational direction opposite from the first rotational direction.
- Claim:
17. A method, comprising: coupling a running tool to a hanger; using the running tool to move the hanger in an axial direction down into a wellhead; temporarily gripping the hanger in the wellhead via a hanger suspension system comprising one or more slips coupled to one or more pistons, wherein temporarily gripping comprises actuating the one or more pistons to drive the one or more slips against the hanger; and rotating a second sleeve relative to a first sleeve of the running tool to rotate an adjustable landing ring to drive a load ring in a radial direction to lock the hanger in place in the wellhead, wherein the one or more slips of the hanger suspension system are separate from the load ring.
- Claim:
18. The method as recited in claim 17 , comprising shearing a shear member to enable the adjustable landing ring to slide under the load ring and drive the load ring in the radial direction to lock the hanger.
- Claim:
19. The method as recited in claim 18 , wherein rotating the second sleeve further comprises rotating the adjustable landing ring along threads to thus move the adjustable landing ring in an axial direction until the load ring is driven radially outwardly into engagement with a profile formed along an interior surface of the wellhead.
- Claim:
20. The method as recited in claim 17 , wherein rotating the second sleeve to rotate the adjustable landing ring to drive the load ring in the radial direction comprises removably coupling the second sleeve to the adjustable landing ring via a castellated interface having a castellation member disposed in a corresponding recess, and the castellation member interfaces with the corresponding recess at a right angle edge to force rotation of the adjustable landing ring in response to rotation of the second sleeve in a first rotational direction; and further comprising releasing the running tool from the hanger and removing the running tool from the wellhead, comprising interfacing the castellation member with the corresponding recess at a sloped edge to cause the castellation member to slide up and out of the corresponding recess in response to rotation of the second sleeve in a second rotational direction opposite from the first rotational direction.
