A system for controlling fluid flow from multiple isolated producing zones in a well is provided. Components of the system are placeable in and retrievable from bottom entry side pocket mandrel sections permanently installed in a production tubing string in the well. These components provided are sensor modules, isolation valve modules, power modules, control modules, hydraulic pump control modules and packer modules which are carried by the production tubing string. Control signals for modules are developed either downhole or at the surface and modules may be placed or retrieved through the production tubing without pulling the production tubing from the well.

1. A system for monitoring and controlling fluid flow from one or more isolated hydrocarbon producing-zones in a borehole, comprising:at least one through tubing sized, electrically powered, flow monitor and control module for measuring fluid flow properties in a cased well borehole, said module being housed in a side pocket of at least one permanent installed mandrel section of a production tubing string in the borehole; and at least one isolation valve module carried by said at least one mandrel for regulating fluid flow from the annulus in said isolated hydrocarbon producing zone to the interior of the production tubing string, wherein said control module actuates said isolation valve module from said side pocket of said mandrel.
