Pressure energized seal actuator ring
An energizing ring for setting a downhole sealing element includes a passage extending through a width of the energizing ring and a wing extending radially outward from a body of the energizing ring, the wing includes a sealing arm coupled to the body at a joint and a slot arranged between at least a portion of the sealing arm and the body, wherein the sealing arm is configured to pivot relative to the joint in response to a fluid pressure within the cavity.
1. A sealing assembly for use in an oil and gas operation, comprising:
a sealing element having a cavity between a first leg and a second leg, the first and second legs coupled together at a bottom of the sealing element and separated at a top by an opening leading to the cavity, and a test port extending through the first leg and the second leg into fluid communication with the cavity; and
an energizing ring adapted for insertion into the cavity, the energizing ring driving the first leg and the second leg in opposite radial directions, the energizing ring comprising:
a passage fluidly coupled to the cavity, the passage extending through a width of the energizing ring; and
a plurality of wings positioned along an inner diameter and an outer diameter of an energizing ring body, each wing of the plurality of wings comprising a sealing arm coupled to the energizing ring body at a joint, the sealing arm separated from at least a portion of the energizing ring body by a slot, wherein the respective sealing arms are configured to pivot relative to the joint in response to a fluid introduced into the cavity.
2. The sealing assembly of claim 1 , wherein the sealing arm is arranged at an angle with respect to an axis of the energizing ring.
3. The sealing assembly of claim 1 , wherein at least one slot is in direct fluid communication with the cavity.
4. The sealing assembly of claim 1 , further comprising:
an insert positioned within at least one slot, the insert driving a respective arm radially outward from the energizing ring body.
5. The sealing assembly of claim 4 , wherein the insert has a flow passage to fluidly couple the slot to the cavity.
6. The sealing assembly of claim 1 , further comprising:
a void space between the test port and the passage, wherein the void space is at least partially isolated by at least one wing of the plurality of wings.
7. The sealing assembly of claim 1 , wherein the sealing arm is arranged substantially parallel to an axis of the energizing ring.
8. The sealing assembly of claim 1 , further comprising:
a longitudinal flow path extending along an axis of the energizing ring, wherein the longitudinal flow path is independent of the passage.
9. A wellbore system, comprising:
a wellhead housing having a bore;
a hanger positioned within the bore; and
a sealing assembly arranged between the hanger and the bore to form a fluid seal, the sealing assembly comprising:
a sealing element having a cavity between a first leg and a second leg, the first and second legs coupled together at a bottom of the sealing element and separated at a top by an opening leading to the cavity, and a test port extending through the first leg and the second leg into fluid communication with the cavity; and
an energizing ring adapted for insertion into the cavity, the energizing ring driving the first leg and the second leg in opposite radial directions, the energizing ring comprising:
a passage fluidly coupled to the cavity, the passage extending through a width of the energizing ring; and
a wing extending radially outward from a body of the energizing ring, the wing comprising a sealing arm coupled to the body at a joint and a slot arranged between at least a portion of the sealing arm and the body, wherein the sealing arm is configured to pivot relative to the joint in response to a fluid pressure within the cavity.
10. The wellbore system of claim 9 , wherein the sealing arm is arranged at an angle with respect to an axis of the energizing ring.
11. The wellbore system of claim 9 , further comprising:
an insert positioned within the slot, the insert driving a respective arm radially outward from the body.
12. The wellbore system of claim 11 , wherein the insert has a flow passage to fluidly couple the slot to the cavity.
13. The wellbore system of claim 9 , wherein the sealing arm is arranged substantially parallel to an axis of the energizing ring.
14. The wellbore system of claim 9 , further comprising:
a longitudinal flow path extending along an axis of the energizing ring, wherein the longitudinal flow path is independent of the passage.
15. The wellbore system of claim 9 , further comprising:
a void space between the test port and the passage, wherein the void space is at least partially isolated by the wing.
16. The wellbore system of claim 9 , further comprising:
a second wing, wherein at least one wing of the wing or the second wing is arranged along an inner diameter of the energizing ring and at least one of the wing or the second wing is arranged along an outer diameter of the energizing ring.
