Abstract
Methods and systems relate to in situ combustion utilizing configurations of injection and production wells to facilitate the in situ combustion. The wells define vertically deviated lengths that have different orientations from one another. Further, heating processes such as resistive heating and cyclic steam stimulation may take place in one or both of the injection and production wells to precondition a reservoir prior to the in situ combustion.
