A system and method for a fully-integrated flow control module (FI-FCM) in a hydrocarbon reservoir is disclosed. The FI-FCM is a unibody structure or a single-piece machined body having a flow meter integrated to the unibody structure. A choke is to be associated within a provision of the FI-FCM that also has an entry flow path for reservoir fluid and an exit flow path for the reservoir fluid. The entry flow path and the exit flow path inside the unibody structure or the single-piece machined body. Fluid communication is enabled between the flow meter, which is upstream relative to the choke, and an entry flow path. The choke is to control flow between the entry flow path and the exit flow path.
