Abstract
A steam generator is located downhole in a well for generating steam to cause viscous crudes to flow out adjacent wells. A packer is mounted above the steam generator. A connector box is located between the packer and the steam generator. An electrical cable extends alongside tubing into the well and into a window in the tubing located just above the packer. The cable extends through a passage in the packer and into the connector box. Feedthrough connectors in the connector box connect the power cable with lead wires extending upward from the steam generator. Cooling fluid passages in the packer allow circulation of cooling fluid from the surface to cool the components. The packer is hydraulically set by water supplied to the cooling fluid passages. A disk ruptures after the packer has been set to enable circulation of the cooling fluid.
