The present invention relates to a method for produce viscous oil in wells through steam injection into horizontal fractures. The objective of the method is achieved through fracturing operations that form a horizontal fracture being this fracture sustained by a sustaining agent, for example, by a bauxite-type, that is resistant to steam in areas of the well (1, 11, 12) that reach the oil-producing formation (6) both in the bottom area (61) and in the top area (62). Vapor, associated or not with another fluid, for example, an organic solvent is injected into the producing well (1, 11, 12) displacing the oil of the formation in a linear manner and through gravity.
