ABSTRACT:
A process for improved safety and productivity when undertaking oil recovery from an underground reservoir by the toe-to-heel in situ combustion process employing a horizontal production well. Water, steam, and/or a non-oxidizing gas, which in the preferred embodiment substantially comprises carbon dioxide which acts as a gaseous solvent, is injected into the reservoir for improving recovery in an in situ combustion recovery process, via either an injection well, a horizontal well, or both.
