Abstract
A downhole steam generation system may include a burner head assembly, a liner assembly, a vaporization sleeve, and a support sleeve. The burner head assembly may include a sudden expansion region with one or more injectors. The liner assembly may include a water-cooled body having one or more water injection arrangements. The system may be optimized to assist in the recovery of hydrocarbons from different types of reservoirs. A method of recovering hydrocarbons may include supplying one or more fluids to the system, combusting a fuel and an oxidant to generate a combustion product, injecting a fluid into the combustion product to generate an exhaust gas, injecting the exhaust gas into a reservoir, and recovering hydrocarbons from the reservoir.
