Resumen:
Given the growing interest in the capture and utilization of CO2 in recent years, several technologies have emerged that seek to generate CO2 in-situ at low cost. The paradigm change not only occurs in technology, but also in the implementation schemes. In order to optimize profitability, it is critical to improve the payout time and the usage of CO2. In contrast, smaller slugs lead to better CO2 utilization rates (oil produced/CO2 injected) while larger slugs lead to faster oil production response. It was observed that due to the high discount rates in the area, faster production response has a higher economic impact that sweep efficiency or breakthrough times. Optimal injection schemes where found for different scenarios and starting the project early is a key parameter for both technical and economic success. Another key technical difference is that the available CO2 volume for injection is constant due to the nature of these capture techniques. Oxycombustion (or other capture methods) produces a continuous stream limiting injection flexibility. CO2 EOR has significant advantages over Chemical EOR due to its significant recovery factors and early response. Also, this technology applies to reservoirs of low permeability and/or high temperature where the polymer can have problems of injectivity or degradation.
