Abstract
Methods and systems relate to recovering petroleum products from an underground reservoir. Injection of steam along with carbon dioxide into the reservoir facilitates the recovering, which is further influenced by operating pressure for the injection. Absorption of the carbon dioxide by the products and heat transfer from the steam to the products act to reduce viscosity of the products in order to aid flowing of the products.
