Abstract

A latch system including a plurality of rocker latches, a rocker support, supporting the plurality of rocker latches, and a movement restrictor in operative connection with each rocker latch of the plurality of rocker latches, the movement restrictor allowing or restricting movement of each rocker latch of the plurality of rocker latches relative to the rocker support. A downhole tool including a sleeve movable relative to other portions of the tool, the sleeve having a profile at an uphole end thereof, an actuator runnable into contact with the sleeve, the actuator including the latch. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a latch system disposed within or as a part of the string. A wet connect system including a first connector housing having a first communication line therein, a second connector housing concentrically positionable in the first connector housing and having a second communication line, and a balance piston fluidly connected to the first communication line.

First claim

What is claimed is:

1. A wet connect system comprising:
a first connector housing having a first communication line therein;
a second connector housing concentrically positionable in the first connector housing and having a second communication line;
a balance piston fluidly connected to the first communication line; and
a latch system comprising:
a plurality of rocker latches;
a rocker support, supporting the plurality of rocker latches; and
a movement restrictor in operative connection with each rocker latch of the plurality of rocker latches, the movement restrictor allowing or restricting movement of each rocker latch of the plurality of rocker latches relative to the rocker support.

2. The system as claimed in claim 1 wherein the balance piston connection to the first fluid communication line is in an annular space between the first connector housing and a sleeve therein.

3. The system as claimed in claim 1 further comprising a running latch having a locking sleeve.

4. The wet connect system as claimed in claim 1 wherein the plurality of rocker latches include insertion faces that collectively form part of a frustum.

5. The wet connect system as claimed in claim 4 wherein the insertion faces are at an angle to a longitudinal axis of the system that is different from an angle to a longitudinal axis of the system of a reception face of a separate sleeve with which the latch system engages, during use.

6. The wet connect system as claimed in claim 5 wherein the insertion face, the reception face or both the insertion face and reception face include a seal material.

7. The wet connect system as claimed in claim 1 wherein each of the plurality of rocker latches includes a rocker recess shaped to facilitate rocking movement on the rocker support.

8. The wet connect system as claimed in claim 1 wherein each of the plurality of rocker latches includes a catch.

9. The wet connect system as claimed in claim 1 wherein the rocker support is a cage.

10. The wet connect system as claimed in claim 1 wherein the movement restrictor is a dog.

11. The wet connect system as claimed in claim 10 wherein the dog includes a seal to prevent debris accumulating adjacent the dog.

12. The wet connect system as claimed in claim 1 further including a resilient retainer tending the plurality of rocker latches to a latched position.

13. The wet connect system as claimed in claim 1 , further including a downhole tool comprising:
a sleeve movable relative to other portions of the tool, the sleeve having a profile at an uphole end thereof;
an actuator in contact with the sleeve.

14. A borehole system comprising:
a borehole in a subsurface formation;
a string in the borehole; and
the wet connect system as claimed in claim 1 disposed within or as a part of the string.

15. A wet connect system comprising:
a first connector housing having a first communication line therein;
a second connector housing concentrically positionable in the first connector housing and having a second communication line;
a rupture disk segregating a fluid of the second communication line until rupture of the disk;
and
a balance piston fluidly connected to the first communication line.
