Abstract
A downhole control method for use in a wellbore that includes deploying a stand-alone power source and a stand-alone hydraulic reservoir downhole; powering a downhole controller using the stand-alone power source; measuring a downhole fluid parameter; and actuating an inflow control device, using the stand-alone hydraulic reservoir and the downhole controller, based on the measured downhole fluid parameter. In one aspect, the stand-alone power source is selected from the group consisting of a battery and a downhole power generator. In another aspect, the stand-alone hydraulic reservoir, the downhole controller, the stand-alone power source, and the inflow control device comprise a remotely-powered, open-hole completion system.
