1. A production/annulus bore stab, comprising:
a unitary body comprising:
a first cylindrical outer surface, a second cylindrical outer surface, and an inner cylindrical surface that defines a central production 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 and a second inlet/outlet, 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 each of the plurality of the individual annulus fluid flow paths are the same length between the first inlet/outlet and the second inlet/outlet;
wherein at least a portion of the unitary body is adapted to be positioned within and sealingly coupled to a production tree that has at least one annulus fluid flow path formed therein in communication with an annulus area directly between a production tubing and a production casing such that the at least one annulus fluid flow path within the production tree is in fluid communication with at least one of the plurality of individual annulus fluid flow paths defined within the unitary body via the first inlet/outlet or the second inlet/outlet.
