摘要： Methods and systems for stimulating light tight shale oil formations to recover hydrocarbons from the formations. One embodiment includes positioning a downhole burner in a first well, supplying a fuel, oxidizer, and water to the burner to form steam, injecting the steam and surplus oxygen into the shale reservoir to form a heated zone within the shale reservoir, wherein the surplus oxygen reacts with hydrocarbons in the reservoir to generate heat; wherein the heat from the reactions with the hydrocarbons and the steam increases permeability in a kerogen-rich portion of the shale reservoir, and producing hydrocarbons from the shale reservoir.
