A spool module for a subsea well production tree and system is presented. The spool module is similar to traditional process modules, except that the spool module includes all its components and their conduits inside one body (or block). This module includes retrievable components used for production and annulus flow lines into one package. The spool module includes the production choke, annulus choke, and conduit bores integral in the block. The spool module includes all of these elements machined into one body having no additional conduits or piping outside of the body. The spool module may also be used in connection with a subsea tree during production of a well, or with several wells on a template or as part of a manifold.
