Abstract

A control line assembly for coupling with a tubing or casing hanger of a wellhead assembly includes a support ring configured to couple with the tubing or casing hanger, and a tubular member configured to extend through a first bore disposed in the support ring, wherein a first end of the tubular member is configured to be stabbed into a passage disposed in a wellhead component of the wellhead assembly, and a second end of the tubular member is configured to be stabbed into a first receptacle disposed in the tubing or casing hanger, wherein, when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger, a passage disposed in the tubular member is configured to provide communication between the passage of the wellhead component and the first receptacle of the tubing or casing hanger.

First claim

What is claimed is:

1. A control line assembly for coupling with a tubing or casing hanger of a wellhead assembly, comprising:
a support ring configured to couple with the tubing or casing hanger, wherein the support ring is configured to be disposed at least partially between the tubing or casing hanger and a wellhead component of the wellhead assembly; and
a tubular member configured to extend through a first bore disposed in the support ring, wherein the tubular member is configured to extend between the tubing or casing hanger and the wellhead component, a first end of the tubular member is configured to be stabbed into a passage disposed in the wellhead component, and a second end of the tubular member is configured to be stabbed into a first receptacle disposed in the tubing or casing hanger;
wherein, when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger, a passage disposed in the tubular member is configured to provide communication between the passage of the wellhead component and the first receptacle of the tubing or casing hanger;
wherein the support ring is configured to be lowered over a neck of the tubing or casing hanger and comprises a plurality of circumferentially spaced first bores configured to receive a plurality of the tubular members;
the support ring comprises a plurality of circumferentially spaced second bores configured to receive a plurality of fasteners; and
the tubing or casing hanger comprises a plurality of circumferentially spaced first receptacles configured to receive the plurality of tubular members and a plurality of circumferentially spaced second receptacles configured to receive and releasably couple with the fasteners.

2. The control line assembly of claim 1 , further comprising:
a plurality of first seal assemblies configured to be received in the first receptacles of the tubing or casing hanger;
wherein each of the first seal assemblies comprises an annular outer seal and an annular inner seal and a frustoconical interface disposed between the outer seal and the inner seal;
wherein each of the tubular members comprises a flange including an annular shoulder configured to apply a compressive force to one of the first seal assemblies when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger.

3. The control line assembly of claim 2 , further comprising:
a guide ring configured to be lowered over the tubing or casing hanger when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger;
wherein the guide ring comprises a first end, a second end, and a plurality of circumferentially spaced bores extending between the first and second ends and configured to receive the plurality of tubular members.

4. The control line assembly of claim 3 , wherein:
the guide ring comprises a plurality of circumferentially spaced apertures extending into the first end of the guide ring, wherein the apertures are aligned with the bores of the guide ring;
the control line assembly further comprises a plurality of spacer rings configured to be received in the receptacles of the guide ring;
the control line assembly comprises a plurality of second seal assemblies configured to be disposed about the tubular members and landed against the spacer rings, wherein each of the second seal assemblies comprises an annular outer seal and an annular inner seal and a frustoconical interface disposed between the outer seal and the inner seal; and
wherein the second seal assemblies are configured to be received in a plurality of receptacles extending into the wellhead component and aligned with a plurality of passages disposed in the wellhead component to seal a connection formed between the passages of the wellhead component and the passages of the tubular members when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger.

5. The control line assembly of claim 1 , wherein an outer surface of the tubular member comprises an annular seal configured to sealingly engage an inner surface of the passage of the wellhead component when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger.

6. A control line assembly for coupling with a tubing or casing hanger of a wellhead assembly, comprising:
a support ring configured to couple with the tubing or casing hanger, wherein the support ring is configured to be disposed at least partially between the tubing or casing hanger and a wellhead component of the wellhead assembly; and
a tubular member configured to extend through a first bore disposed in the support ring, wherein the tubular member is configured to extend between the tubing or casing hanger and the wellhead component, a first end of the tubular member is configured to be stabbed into a passage disposed in the wellhead component, and a second end of the tubular member is configured to be stabbed into a first receptacle disposed in the tubing or casing hanger;
wherein, when the control line assembly is coupled with the tubing or casing hanger and the wellhead component is landed over the tubing or casing hanger, a passage disposed in the tubular member is configured to provide communication between the passage of the wellhead component and the first receptacle of the tubing or casing hanger and the control line assembly further comprising:
a plurality of the support rings, wherein each support ring is configured to be received in one of a plurality of first receptacles of the tubing or casing hanger; and
a plurality of first seal assemblies configured to be received in the plurality of first receptacles of the tubing or casing hanger;
wherein, the support rings are configured to apply a compressive force to the first seal assemblies in response to the application of torque to the support rings.

7. The control line assembly of claim 6 , wherein an outer surface of each support ring comprises male threads configured to releasably couple with female threads disposed on an inner surface of each first receptacle of the tubing or casing hanger.

8. A method for installing a tubing or casing hanger in a wellhead assembly, comprising:
coupling a control line assembly to the tubing or casing hanger, wherein the control line assembly comprises a support ring and a tubular member having a first end and a second end, wherein the second end is received in a first receptacle of the tubing or casing hanger, the tubular member extends through a first bore disposed in the support ring, and the support ring couples to the tubing or casing hanger to support the tubular member;
landing the tubing or casing hanger in a housing of the wellhead assembly;
landing a wellhead component over a first end of the tubing or casing hanger; and
stabbing the first end of the tubular member into a passage disposed in the wellhead component, wherein the tubular member extends between the tubing or casing hanger and the wellhead component, and the support ring is disposed at least partially between the tubing or casing hanger and the wellhead component.

9. The method of claim 8 , further comprising:
coupling the tubing or casing hanger with a running tool; and
stabbing the first end of the tubular member into a passage disposed in the running tool to provide communication between the passage of the running tool and the first receptacle of the tubing or casing hanger.

10. The method of claim 8 , further compr
