ABSTRACT

The best technological alternative known so far to reduce emissions into the atmosphere of the largest greenhouse gas, carbon dioxide, in the short and medium term, is the capture, utilization and geological storage of CO₂ (CCUS). This aspect allows the continued use of fossil fuels while moving towards the massive and comprehensive development of renewable energies. Achieving a significant reduction in CO₂ emissions requires knowledge of the available CO₂ storage capacity. This research shows a methodology for calculating the geological storage capacity in the part of the porous volume previously occupied by hydrocarbons can be occupied by an equivalent volume of CO₂ at reservoir pressure and temperature conditions. The proposed calculation methodology (UCCGCO2) has an estimation efficiency between 90 and 98% was determined to the values obtained currently available methodologies, and its use is simpler than these.

Keywords: geological storage of CO₂, carbon dioxide, reservoir, storage capacity.
