The aim of this study is to conduct a review of practices related to enhanced hydrocarbon recovery processes with CO2 (CO2-EOR) combined with permanent geological storage (CCUS) in Mexico. The study focused on the assessment of the requirements that need to be met by CO2 EOR projects to qualify as CO2 permanent storage projects (CCS). In Mexico, the first pilot project of its kind will be held by PEMEX in the southeastern region fields.

Techniques and operation for CCUS have been developed for decades through the experience in EOR-CO2 processes in the oil industry. Barriers and uncertainties in these types of operations, where improved recovery and geological storage of CO2 is combined, are not technical but economic and political – related.

Some of the requirements are very similar to those traditionally developed in the oil industry, but some others require additional efforts and investments to ensure the permanent storage of CO2 underground. In order to achieve this, a detailed program of monitoring, reporting and verification (MRV) to monitor the behavior of CO2 has to be carried out.
This study is part of the collaborative effort between the World Bank and the Government of Mexico to support the development and deployment of CCUS technology in the country.
