Abstract

Methods and systems produce petroleum products from a formation by a steam assisted process followed by an in situ combustion process. The steam assisted process utilizes an injector and first producer to form a steam chamber within the formation as the products are recovered. The in situ combustion then starts by injecting an oxidant into the formation and ignition of residual products. A combustion front advances toward a second producer that may be offset in a lateral direction from the first producer. Heat and pressure from the in situ combustion sweeps the products ahead of the combustion front to the second producer for recovery.
