Claim Text:
1. A system for providing electrical power in a subterranean well, the system comprising: (a) a radioisotope thermoelectric generator positioned and installed in a downhole location; (b) the radioisotope thermoelectric generator comprising: (c) the radioisotope thermoelectric generator being configured for flowing heat from the core to the thermocouple to produce electricity; (d) providing a production packer in the subterranean well, the radioisotope thermoelectric generator being positioned below the production packer; (e) providing a production tubing extending below the production packer in the subterranean well; (f) providing at least one electric interval control valve in the subterranean well, the electric interval control valve being positioned below the production packer, the electric interval control valve being adapted for regulating reservoir flow to the production tubing of the subterranean well; (g) transmitting the electricity along a conductive cable to the electric interval control valve in the subterranean well to regulate the electric interval control valve, thereby regulating flow from the subterranean formation to the production tubing wherein the conductive cable is located in the annulus between a production string and the production tubing thereby connecting the electric interval control valve with the radioisotope thermoelectric generator; (h) wherein flow into the subterranean well may be regulated using electrical power wherein such electrical power is generated at a position below the production packer; and (i) wherein cabled transmission of electrical power across a packer is not required in the system.
