Patent ID: 7073577

Claim:
A method of recovering hydrocarbons from a subterranean reservoir, the method comprising: (a) drilling an injection well bore into the subterranean reservoir, the injection well bore having an outlet; (b) drilling a production well bore into the subterranean reservoir, the production well bore being spaced apart from the injection well bore and having an inlet; (c) forming a permeable zone comprising a first patterned web of channels radiating outwardly from the outlet of the injection well bore and connecting to a second patterned web of channels radiating outwardly from the inlet of the production well bore in the subterranean reservoir; and (d) flowing a heated fluid from the outlet of the injection well bore and into the permeable zone to mobilize hydrocarbons in the subterranean reservoir so that the mobilized hydrocarbons flow toward the inlet of the production well bore.
