Resumen
The present work aims to evaluate the economic viability of steam and solvent injection in reservoirs, which presents characteristics of heavy oil, as a method of oil recovery. The research is classified as quantitative in its approach and its objectives. From the simulations performed in the studies of Cavalcante (2014), for a 15-year project, it was possible to obtain the annual data of oil production, water production, steam injection, solvent injection of several projects in which some alterations were made. operating parameters. These data were used to calculate Net Present Value (NPV). With the results found, it was concluded that the best technical results did not necessarily obtain higher economic returns, since the impact of steam and solvent costs impacted more than the improvement in oil recovery results. After analyzing these results, the 4 best NPV results were selected to continue analyzing the Internal Rate of Return (IRR) and Payback. The IRR value in the 4 projects studied was higher than the minimum attractiveness rate, meaning that the projects could be economically adopted. For the cases analyzed, the payback always returned in the first years of the project, reaching a maximum of about two and a half years. The oil recovery project through the injection of steam and solvent with injection flow of 50 m³ / day with 5% injected solvent presented the best results, and is the project indicated for application by this research. The maximum NPV of this project exceeds $ 7.3 million in 10 years of the project, the IRR was 87.92% and the payback is achieved in about a year and a half.
