Abstract
A method is described for accelerating start-up for SAGD-type operation by providing radio frequency heating devices inside the lateral wells that can re-heat the injected steam after losing heat energy during the initial injection. The method also extends the lateral wells such that the drilling of vertical wells can be reduced to save capital expenses.
