**2.1 Criteria for the choice of the geographical area for the storage of CO2**

According to Bachu [6], it is necessary to evaluate, at the basin scale, the suitability for CO2 sequestration in sedimentary rocks, among which are the following aspects:


Considering the above, a roadmap is proposed for the implementation of this method in geological media [7]:

**Assessment of suitability at the regional level**, to determine the areas of a basin that could become suitable and the means of storage, which include the following


**Inventory of feasible sites for CO2 storage**, which initially requires the identification of the main sources of CO2, followed by a local-level characterization considering the pressure and temperature *in situ*, as well as properties of hydrocarbons.

**Safety of CO2 storage operations**, where it is secure that there will be no upward migration of CO2 and leakage to other beds during or after introduction, which could occur through open geological faults and natural or man-induced fractures, irrespective of storage media.

**Storage capacity**, for EOR operations in mature stage oil and gas deposits, storage pore volume, grade of water penetration as a result of oil production, and CO2 solubility are crucial components in judging storage capacity.
