Abstract
A system in some embodiments includes sealing system including an energizing member that simultaneously seats a plurality of sealing elements about a plurality of control lines, respectively. Further embodiments provide a method including disposing a plurality of sealing elements about a plurality of control lines, respectively, and fastening an energizing member to simultaneously seat each of the sealing elements.
Claims19
A system, comprising:
- a control line configured to extend into a bore;
- an annular seal coaxial with and surrounding the control line, wherein the annular seal comprises a load ring or a ferrule disposed in the same bore as the control line;
- a fastener at an offset and external from the control line and the annular seal;
- and
- an energizing member configured to bias the annular seal toward a seated position with the control line in response to movement of the fastener.
2 more elements
A system, comprising:
- a plurality of load rings configured to mount around and move axially about a plurality of control lines, wherein a first load ring surrounds a first control line but not a second control line, and a second load ring surrounds the second control line but not the first control line;
- and an energizing member configured to bias the plurality of load rings for simultaneously energizing and seating a plurality of sealing elements about the plurality of control lines, respectively.
A system, comprising:
- a control block comprising a plurality of passages each having a control line and an annular seal coaxial with the control line, wherein a force applied to an energizing member is configured to simultaneously couple and seat the annular seals coaxially with the control lines associated with the plurality of passages, respectively;
- and
- a fastener offset and external from the passages and the annular seal, wherein the fastener is configured to provide the force to the energizing member.
