Abstract

A well intervention tool includes a Christmas tree (XT) adapter connected to an XT, a tubing hanger interface tool aligned axially within the adapter mandrel, and a stab connected to the tubing hanger interface tool, the stab contacting at least one internal component of the XT. The XT includes an XT mandrel. The XT adapter includes an adapter mandrel positioned above the XT mandrel. A system with a well intervention tool includes a blowout preventer (BOP). A system also includes a BOP-integrated adapter that includes a BOP and an XT adapter.

Claims (34)

1 . A well intervention tool, comprising:

an XT adapter connected to an XT, the XT including an XT mandrel, wherein the XT adapter comprises an adapter mandrel positioned above the XT mandrel;

a tubing hanger interface tool aligned axially within the adapter mandrel; and

a stab connected to the tubing hanger interface tool, wherein the stab contacts an internal tree cap or a tubing hanger.

2 . The well intervention tool of claim 1 , wherein the stab is connected to the tubing hanger interface tool by a threaded connection.

3 . The well intervention tool of claim 1 , further comprising:

A metal-to-metal seal between the stab and the internal tree cap or the tubing hanger.

4 . The well intervention tool of claim 1 , further comprising:

a polymeric or elastomeric seal between the stab and the internal tree cap or the tubing hanger.

5 . The well intervention tool of claim 1 , wherein the adapter mandrel and the tubing hanger interface tool are connected using dogs or an actuation sleeve.

6 . A system, comprising:

a BOP;

an XT; and

an intervention system, comprising:

an adapter mandrel, the adapter mandrel axially aligned with a bore of the XT;

an adapter connection positioned to couple the adapter mandrel to the XT;

a tubing hanger interface tool positioned to extend through the adapter mandrel; and

a stab connected to the tubing hanger interface tool, wherein the stab contacts an internal tree cap or a tubing hanger.

7 . The system of claim 6 , wherein the stab is connected to the tubing hanger interface tool by a threaded connection.

8 . The system of claim 6 , further comprising:

a metal-to-metal seal between the stab and the internal tree cap or the tubing hanger.

9 . The system of claim 6 , further comprising:

a polymeric or elastomeric seal between the stab and the internal tree cap or the tubing hanger.

10 . The system of claim 6 , wherein the adapter mandrel and the tubing hanger interface tool are connected using dogs or an actuation sleeve.

11 . A system, comprising:

an XT; and

an intervention system, comprising:

a BOP-integrated adapter, comprising an XT adapter and a BOP;

a tubing hanger interface tool positioned to extend through the BOP-integrated adapter; and

a stab connected to the tubing hanger interface tool, wherein the stab contacts an internal tree cap or a tubing hanger.

12 . The system of claim 11 , wherein the stab is connected to the tubing hanger interface tool by a threaded connection.

13 . The system of claim 11 , further comprising:

a seal between the stab and the one or more components of the XT, the seal comprising one of a metal-to-metal seal, a polymeric seal, or an elastomeric seal.

14 . The system of claim 11 , wherein the XT adapter of the BOP-integrated adapter and the tubing hanger interface tool are connected using dogs or an actuation sleeve.
