Preliminary Screening and Ranking Assessment for Carbon Capture Use and Storage (CCUS) in Colombia Sedimentary Basins.

Underground CO2 storage capacity is considered nowadays as a resource according to the SPE, CO2 Storage Resources Management System of 2017, and one of the most accepted alternatives to mitigate the effects of global warming. Proper estimation and use of this resource represents different technological challenges, which includes guarantee CO2 permanence underground for long periods of time and preventing to reach the atmosphere. Identify this resource in the sedimentary basins of Colombia is the main objective of this research paper, where 23 basins were evaluated and categorized adjusting the method of objective metrics proposed for the basins in Canada in 2003 and modified for the basins in Australia (2007), Cambodia and Spain (2014). Results show that the basin with the best containment security is the offshore Colombia Basin (55%); the best basin with storage capacity is the Llanos Basin (73%) and the best basin with technological feasibility is the Middle Magdalena Valley (86%). In the same way it was possible to conclude that the most suitable basins for underground CO2 storage projects are the Middle Magdalena Valley (66%), followed by Llanos basin (63%) and Sinu San Jacinto basin (61%).
