This research proposes the implementation of a cyclic steam injection improved solvent technique in a colombian heavy oil reservoir and its technical evaluation using the recovery factor as main criteria. Numerical reservoir simulation was used to observe the behavior of cold production in a well, which was subsequently subjected to ten cycles of steam injection and steam-solvent injection. In this procedure, optimizations of operational parameters as the injection times, soaking and production, the concentration of solvent used, the operating pressure and rates of steam and solvent were performed. Analysis results of the application of improved solvent cycles is included at the end, from a technical and financial standpoint.
