Abstract
A method for heating heavy oil inside a production well. The method raises the subsurface temperature of heavy oil by utilizing an activator that has been injected below the surface. The activator is then excited with a generated non-microwave frequency from 0.1 MHz to 300 MHz such that the excited activator heats the heavy oil.
