Abstract
A process of igniting a downhole generator having a fuel conduit and an oxidizing fluid conduit extending from the surface to the generator for supplying a fuel and an oxidizer to its chamber. Coupled to the two conduits near the generator are two solenoid control valves which are controlled from the surface. In carrying out the process, the valves are closed and a slug of hypergolic fuel is injected into the fuel conduit and an oxidizing fluid injected into the oxidizing fluid conduit. A generator fuel is injected into the fuel conduit behind the hypergolic fuel. The two valves are opened to allow the hypergolic fuel and oxidizer to pass into the chamber to cause spontaneous ignition of the hypergolic fuel to ignite the generator fuel and an oxidizer which follow.
