Abstract

A tubing hanger running tool assembly includes a ring extending around a tubing hanger in a wellhead, and having a contracted configuration and an expanded configuration. The ring in the expanded configuration is received into a groove in the wellhead. The assembly includes a sleeve to actuate the ring between the contracted and expanded configurations. The sleeve includes a tubing hanger running tool received through the sleeve and having a lower end that is configured to be received into a first bore of the tubing hanger and to form a connection therewith. The tubing hanger running tool is configured to transmit an axial force to the sleeve in response to the tubing hanger running tool being received into the tubing hanger. The axial force moves the sleeve axially with respect to the ring, which actuates the ring between the contracted and expanded configurations.

First claim

What is claimed is:

1. A tubing hanger running tool assembly, comprising:
a ring that is configured to extend around a tubing hanger in a wellhead, wherein the ring has a contracted configuration and an expanded configuration, the ring in the expanded configuration being configured to be received into at least one groove in the wellhead;
a sleeve configured to selectively engage the ring so as to actuate the ring between the contracted and expanded configuration;
a bearing plate defining a first bore that is configured to align with a first bore of the tubing hanger and a second bore that is configured to align with a second bore of the tubing hanger; and
a tubing hanger running tool received through the sleeve and comprising a lower end that is configured to be received into the first bore of the tubing hanger, wherein the lower end is configured to form a connection with the first bore of the tubing hanger,
wherein the tubing hanger running tool is configured to transmit an axial force to the sleeve in response to the tubing hanger running tool being received into the tubing hanger, wherein the axial force moves the sleeve axially with respect to the ring, and wherein moving the sleeve axially relative to the ring actuates the ring between the contracted and expanded configurations.

2. The tubing hanger running tool assembly of claim 1 , further comprising an indexing plate coupled to the tubing hanger, wherein the indexing plate is movable responsive to axial translation of the sleeve from a first position relative to the tubing hanger to a second position relative to the tubing hanger, the indexing plate in the second position being configured to actuate the ring to the expanded configuration.

3. The tubing hanger running tool assembly of claim 1 , further comprising a proximity sensor received through the wellhead and configured to provide a signal representing that the ring has been received into the groove.

4. The tubing hanger running tool assembly of claim 1 , wherein the connection formed by the lower end of the tubing hanger running tool with the first bore of the tubing hanger is a threaded connection, and wherein the tubing hanger running tool is configured to transmit the axial force to the sleeve in response to the tubing hanger running tool being rotated relative to the tubing hanger.

5. The tubing hanger running tool assembly of claim 1 , wherein the sleeve further comprises the bearing plate, and wherein the first and second bores of the bearing plate are eccentrically positioned with respect to a centerline of the bearing plate.

6. The tubing hanger running tool assembly of claim 5 , wherein a wellhead electrical penetrator is received through the second bore of the bearing plate and the second bore of the tubing hanger, and wherein a production tubing is coupled to the first bore of the tubing hanger.

7. The tubing hanger running tool assembly of claim 5 , wherein the tubing hanger running tool comprises a shoulder that transmits axial force to the sleeve, so as to move the sleeve upward or downward with respect to the ring.

8. The tubing hanger running tool assembly of claim 7 , further comprising a first bearing insert positioned between the shoulder and the bearing plate of the sleeve, the first bearing insert being configured to transmit an axial downward force from the shoulder to the sleeve while permitting the tubing hanger running tool to rotate with respect to and while engaging the sleeve.

9. The tubing hanger running tool assembly of claim 8 , wherein the first bearing insert comprises a first bore and a second bore, the first and second bores of the first bearing insert being aligned with the first and second bores, respectively, of the bearing plate.

10. The tubing hanger running tool assembly of claim 7 , wherein the ring is biased toward the expanded configuration, and wherein a lower end of the sleeve retains the ring in the contracted configuration until the tubing hanger running tool is rotated and the sleeve is moved axially away from the ring.

11. The tubing hanger running tool assembly of claim 10 , further comprising:
an upper collar coupled to an upper end of the sleeve, wherein rotating the tubing hanger running tool in a first direction relative to the tubing hanger causes the tubing hanger running tool to apply an axially upward force on the upper collar, which drives the sleeve upward, away from the ring, and wherein rotating the tubing hanger running tool in a second direction relative to the tubing hanger causes the tubing hanger running tool to apply an axially downward force on the bearing plate, which drives the sleeve downward, toward the ring; and
an upper bearing insert positioned axially between the upper collar and the bearing plate, the tubing hanger running tool being received through the upper bearing insert, wherein the shoulder is configured to bear against the upper bearing insert so as to transmit the axially upward force thereto.

12. The tubing hanger running tool assembly of claim 1 , wherein the ring is biased toward the contracted configuration, and wherein a lower end of the sleeve is configured to be received radially between the tubing hanger and the ring, such that rotating the tubing hanger running tool in a second direction presses the sleeve downward, and pressing the sleeve downwards forces the ring from the contracted configuration to the expanded configuration.

13. The tubing hanger running tool assembly of claim 1 , wherein the ring comprises a split ring or a segmented ring that is either biased radially outward or radially inward.

14. A system, comprising:
a wellhead defining a central bore therein and a groove extending at least partially around the bore;
a tubing hanger received into the central bore of the wellhead, the tubing hanger defining a first bore and a second bore extending therethrough, the first bore for being connected to a production tubing;
a ring positioned around the tubing hanger and having a contracted configuration in which the ring does not prevent the tubing hanger from moving relative to the wellhead, and an expanded configuration in which the ring is received at least partially into the groove and is configured to prevent the tubing hanger from moving axially upwards with respect to the wellhead;
a tubing hanger running tool received into the first bore of the tubing hanger, wherein the tubing hanger comprises a threaded lower end that forms a threaded connection with the first bore;
a sleeve positioned around the tubing hanger running tool and the tubing hanger, wherein the sleeve is axially movable by rotating the tubing hanger running tool relative to the tubing hanger, and wherein the sleeve is configured to actuate the ring between the expanded and contracted configurations by moving axially with respect to the tubing hanger; and
a bearing insert positioned below the sleeve and adjacent to a shoulder of the tubing hanger running tool, wherein the bearing insert defines a first bore that is configured to align with the first bore of the tubing hanger and a second bore that is configured to align with a second bore of the tubing hanger.

15. The system of claim 14 , wherein the sleeve comprises a bearing plate therein having a first bore through which the tubing hanger running tool extends and a second bore, the tubing hanger running tool comprises a radially-extending shoulder that transmits a downward axial force to the bearing plate in response to the tubing hanger running tool rotating with respect to the tubing hanger, wherein the downward axial force moves the sleeve downward toward the ring.
