Abstract
One illustrative production/annulus bore stab disclosed herein includes a one-piece body that comprises a first cylindrical outer surface and a second cylindrical outer surface and a plurality of individual fluid flow paths defined entirely within the one-piece body. In this illustrative example, each of the individual fluid flow paths is fluidly isolated from one another and each of the fluid flow paths comprise a first inlet/outlet at a first end of the fluid flow path that is positioned in the first cylindrical outer surface and a second inlet/outlet at a second end of the fluid flow path that is positioned in the second cylindrical outer surface.

A subsea system, comprising:
- an item of equipment, comprising:
- a first fluid flow path, an annulus fluid flow path, and an annulus fluid collection chamber;
- and
- a one-piece central/annulus bore stab comprising:
- a unitary body having a first cylindrical outer surface, a second cylindrical outer surface, and an inner cylindrical surface that defines a central bore, and
- a plurality of individual annulus fluid flow paths defined entirely within the unitary body, each of the individual annulus fluid flow paths being fluidly isolated from one another within the unitary body, each of the individual annulus fluid flow paths comprising a first inlet/outlet at a first end of the fluid flow path and a second inlet/outlet at a second end of the fluid flow path, wherein the first inlet/outlet is positioned in the first cylindrical outer surface and the second inlet/outlet is positioned in the second cylindrical outer surface;
- wherein at least a first portion of the unitary body is adapted to be positioned within and sealingly coupled to the item of equipment such that the plurality of individual annulus fluid flow paths defined within the unitary body are in fluid communication with the annulus fluid collection chamber via the first inlet/outlets or the second inlet/outlets and the central bore of the central/annulus bore stab is in fluid communication with the first fluid flow path of the item of equipment.
A subsea system, comprising:
- a tree comprising:
- a valve block that defines a first fluid flow path, an annulus fluid flow path, and an annulus fluid collection chamber;
- and
- a central/annulus bore stab, comprising:
- a central fluid flow path defined through a unitary body, the central fluid flow path in fluid communication with the first fluid flow path of the tree, and
- a plurality of individual annulus fluid flow paths defined entirely within the unitary body, each of the individual annulus fluid flow paths being fluidly isolated from one another within the unitary body, each of the individual annulus fluid flow paths comprising a first inlet/outlet at a first end of the fluid flow path positioned in a first cylindrical outer surface of the unitary body and a second inlet/outlet at a second end of the fluid flow path positioned in a second cylindrical outer surface of the unitary body, each of the first inlet/outlets located at a common first longitudinal position of the unitary body and each of the second inlet/outlets located at a common second longitudinal position of the unitary body;
- wherein at least a first portion of the unitary body is sealingly coupled to the tree such that the plurality of individual annulus fluid flow paths defined within the unitary body are in fluid communication with the annulus fluid collection chamber via the first inlet/outlets.
