Jack E Bridges, Allen Taflove, Guggilam C Sresty: Single well stimulation for the recovery of liquid hydrocarbons from subsurface formations. IIT Research Institute, Fitch Even Tabin & Flannery, June 25, 1985: US04524827 (300 worldwide citation)

Water is vaporized in an annular upper region of a subsurface formation into which borehole extends from the surface. This creates a substantially nonconducting dielectric in such region extending outwardly from the borehole. Such vaporization is preferably achieved by the application of electrical ...
