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.

Claims (10)

1. A production/annulus bore stab, comprising:

a one-piece body comprising 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, each of the individual fluid flow paths being fluidly isolated from one another within the one-piece body, each of the 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 portion of the one-piece body is adapted to be positioned within and sealingly coupled to an item of equipment that has at least one fluid flow path formed therein such that the at least one fluid flow path within the item of equipment is in fluid communication with at least one of the plurality of individual fluid flow paths defined within the one-piece body via the first inlet/outlet or the second inlet/outlet.

2. The production/annulus bore stab of claim 1 , wherein the item of equipment is one of a tubing hanger or a valve block of a production tree.

3. A system, comprising:

an item of equipment comprising at least one fluid flow path formed therein; and

a production/annulus bore stab comprising:

a one-piece body comprising a first cylindrical outer surface and a second cylindrical outer surface, wherein at least a portion of the one-piece body is positioned within and sealingly coupled to the item of equipment; and

a plurality of individual fluid flow paths defined entirely within the one-piece body, each of the individual fluid flow paths being fluidly isolated from one another within the one-piece body, each of the 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 the at least one fluid flow path within the item of equipment is in fluid communication with at least one of the plurality of individual fluid flow paths defined within the one-piece body via the first inlet/outlet or the second inlet/outlet; wherein the at least one fluid flow path is in fluid communication with an annulus fluid collection chamber.

4. The system of claim 3 , wherein the item of equipment is one of a tubing hanger or a valve block of a production tree.
