ABSTRACT:
A downhole, modular, well-monitoring and control system is disclosed for use as a stand alone system capable of being left unconnected to the surface in a cased and completed well borehole. Annular shaped interchangeably connected modules, each having a centrally located fluid flow pathway through them, are connected in end to end relationship to each other. Seating modules, sensor and flow control modules, power supply modules and other modules form the functional basis for a complete stand alone downhole system to monitor and control production in multiple zone completed wells. The system may be interrogated and reprogrammed from the surface without removing modules from the well.
