ABSTRACT:
Hydrocarbons trapped in solid media, such as bitumen in tar sands may be recovered from deep formations by relieving the stress of the overburden and causing the formation to flow from an injection well to a production well, for example, by fluid injection, recovering a tar sand/water mixture from the production well, separating the bitumen and reinjecting the remaining sand in a water slurry.
