Abstract:
A method to extract bitumen or very heavy oil in situ from oil sand seams close to the Earth's surface is provided. Energy is introduced via at least two pipes at a given, repeatable distance from the seam, a predefined geometry is maintained in relation to the well pair. The associated apparatus includes at least one additional pipe which is alternatively designed as an electrode or also for feeding vapor and is placed above the injection pipe.
