| 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. | ||||||

| A modular assembly for a wellhead has a housing and a plurality of modular cartridges. The housing connects with a studded or flanged connection to the wellhead, which can have a tubing adapter, casing hanger, etc. The modular cartridges can interchangeably stack in the housing's internal pocket so that the bores of the stacked cartridges configure the through-bore of the assembly communicating the wellhead with external components, such as flow lines, capillary lines, etc. The modular cartridges include a spacer cartridge, a hanger cartridge, a valve cartridge, and a cross cartridge. The spacer cartridge can be used to space other cartridges in the internal pocket, and the hanger cartridge can be used to support capillary strings and/or velocity strings in the wellhead. The valve cartridges have valve elements that can be opened and closed by bonnets that affix externally to the housing. The cross cartridge can have one or more cross ports to divert the assembly's through-bore to additional flow components, such as flow lines, wing valves, chokes, and the like. | ||||||
