**1. Introduction**

Global warming is an imminent threat to humanity, and it is related to CO2 emissions in the atmosphere, which is mainly the product of the combustion of hydrocarbons (oil and gas), coal in power plants, and other industrial plants.

Considering the above, carbon capture use and geological storage (CCUS) is being considered as one of the methods to reduce greenhouse gas emissions, thus applying the methods of optimizing the operation of the different projects of enhanced oil recovery (EOR) by using carbon dioxide (CO2), becoming the tool to improve efficiency and profitability in the production of the hydrocarbons sector. In this way, it contributes responsibly to sustainable development in energy projects [1].

The geological, geothermal, and hydraulics properties of the Eastern Llanos basin are favorable for the storage of CO2. Considering the main criteria for the application of these projects, especially in the cases of mature deposits, it would become an applicable method to increase the production of hydrocarbons through improved recovery and thus increase their useful life.
