Abstract

There is provided a system and method for installing a wellhead component in a single trip. Generally, a wellhead component may be run into a wellhead using a running tool. The running tool may then be retrieved from the wellhead and replaced with a locking tool, which is also run into the wellhead. Additional tools may be used to over-pull the wellhead component and to cementing the wellhead component in place. The process of retrieving and running tools into the wellhead is both time-consuming and costly. Accordingly, the disclosed embodiments include a one-trip tool configured to run a wellhead component into a wellhead, engage an internal coupling to lock the wellhead component in place, over-pull the wellhead component to ensure the internal coupling was properly engaged, and cement the wellhead component in place within the wellhead.

First claim

The invention claimed is:

1. A system, comprising:
a one-trip tool, comprising:
a first tool portion; and
a second tool portion coupled to the first tool portion at a first connection, wherein the second tool portion is configured to couple to a hanger at a second connection, and the first tool portion is configured to rotate relative to the second tool portion to drive axial movement of a tapered interface to generate a radial force to energize a hanger coupling disposed about the hanger while the second tool portion remains coupled to the hanger via the second connection.

2. The system of claim 1 , wherein the first connection comprises a first threaded connection.

3. The system of claim 2 , wherein the second connection comprises a second threaded connection.

4. The system of claim 3 , wherein the first and second threaded connections have a common thread handedness, the one-trip tool is configured to rotate in a first rotational direction to advance the first and second threaded connections due to the common thread handedness, and the one-trip tool is configured to rotate in a second rotational direction to extract the first and second threaded connections due to the common thread handedness.

5. The system of claim 3 , wherein the second threaded connection is disposed along an inner circumference of the second tool portion and is configured to couple to an outer circumference of the hanger.

6. The system of claim 2 , wherein the first connection comprises an upper axial block structure and a lower axial block structure configured to limit a range of axial movement between the first and second tool portions via rotation along the first threaded connection.

7. The system of claim 1 , wherein the first and second tool portions are coaxial with one another, the first tool portion is disposed about the second tool portion, and the second tool portion is configured to extend about an outer circumference of the hanger.

8. The system of claim 7 , wherein the one-trip tool comprises a sleeve extending from the first tool portion about the second tool portion, the sleeve is configured to extend about the outer circumference of the hanger, and the sleeve is configured to drive the axial movement of the tapered interface to generate the radial force to energize the hanger coupling in response to rotation between the first and second tool portions.

9. The system of claim 8 , wherein the sleeve is coupled to the first tool portion with a shear structure configured to shear after the hanger coupling is energized by the sleeve.

10. The system of claim 9 , wherein the first tool portion is configured to rotate relative to the sleeve after shearing of the shear structure upon exceeding a load.

11. The system of claim 1 , comprising the hanger coupling, wherein the hanger coupling comprises a lock ring.

12. The system of claim 11 , wherein the hanger coupling comprises an energizing ring, and the energizing ring is configured to drive radial movement of the lock ring via the tapered interface in response to a driving force from the first tool portion.

13. The system of claim 1 , comprising the hanger.

14. The system of claim 1 , comprising one or more openings or recesses in the one-trip tool configured to facilitate flow of cement.

15. The system of claim 1 , wherein the one-trip tool is configured to rotate the first tool portion in a first rotational direction relative to the second tool portion to drive the tapered interface to energize the hanger coupling while holding the second connection between the second tool portion and the hanger, and the one-trip tool is configured to rotate in a second rotational direction to disengage the second connection between the second tool portion and the hanger.

16. A system, comprising:
a one-trip tool, comprising:
a first tool portion;
a sleeve coupled to the first tool portion via a shear structure, wherein the shear structure is configured to transfer a force from the first tool portion to the sleeve in response to movement of the first tool portion; and
a second tool portion coupled to the first tool portion at a first connection, wherein the second tool portion is configured to couple to a tubular of a mineral extraction system at a second connection, the first tool portion is configured to move relative to the second tool portion causing the shear structure to transfer the force to the sleeve to drive the sleeve to energize a coupling disposed about the tubular while the second tool portion remains coupled to the tubular via the second connection, and the shear structure is configured to shear after the coupling is energized by the sleeve.

17. The system of claim 16 , wherein the first connection comprises a first threaded connection, the second connection comprises a second threaded connection, the first and second threaded connections have a same handedness of threads, the one-trip tool is configured to rotate in a first rotational direction to advance the first and second threaded connections due to the same handedness of threads, and the one-trip tool is configured to rotate in a second rotational direction to extract the first and second threaded connections due to the same handedness of threads.

18. The system of claim 16 , wherein the shear structure is configured to shear upon exceeding a torque, and the first tool portion is configured to rotate relative to the sleeve upon shearing of the shear structure.

19. The system of claim 16 , wherein the first tool portion is configured to rotate relative to the second tool portion to drive the sleeve to energize the coupling disposed about the tubular via a tapered interface while the second tool portion remains coupled to the tubular via the second connection.

20. A method, comprising:
rotating a first tool portion in a first rotational direction relative to a second tool portion at a first rotational connection of a one-trip tool while holding a second rotational connection between the second tool portion and a tubular of a mineral extraction system, wherein the second rotational connection disengages in a second rotational direction opposite from the first rotational direction; and
driving a tapered interface to energize a coupling disposed about the tubular in response to the rotation of the first tool portion.

21. The method of claim 20 , wherein energizing the coupling comprises driving a sleeve coupled to the first tool portion to bias a lock ring of the coupling to move in a radial direction via the tapered interface.

22. The method of claim 20 , comprising shearing a shear structure in response to rotating the first tool portion after energizing the coupling.

23. The method of claim 20 , comprising rotating the first tool portion in the second rotational direction to cause disengagement of the second rotational connection.
