Abstract
Several downhole flow control devices are disclosed which are meterable and are also capable of shutting of a particular zone in a well. The several embodiments include a multiple valve body, a toroidal inflatable valve, and a series of related choke systems. The downhole flow control choke mechanisms each include a downhole electronics package to provide programming or decision making capacity as well as motor actuation systems. Each choke mechanism also includes a system whereby the device can be converted to manual operation and actuated by a conventional shifting tool.
