MMV long term strategies to calibrate and support CO2 storage flow models using focused seismic

Paper presented at the EAGE GeoTech 2022 – London, UK , April 2022, and written by Habib Al Khatib.


To substantially reduce global greenhouse gas emissions to limit the global temperature increase in
this century to 2 degrees Celsius while pursuing efforts to limit the increase even further to
1.5 degrees” as stated in the Paris Agreement (UN, 2015), most greenhouse gas control scenario include
massive CO2 geological storage also called CCS. According to the IEA, from over 40 Mtpa CO2 in
2021, CCS yearly capacity needs to increase to 1.6 Gtpa CO2 in 2030 (IEA, 2021). To make it happen,
subsurface industry will have to overcome (amongst other) the following two critical challenges: social
acceptance and Monitoring, Measurement and Verification (MMV) as technically and economically
viable for long term monitoring (50-100 years) (Lumley, 2021).

In this abstract, pros & cons of frequent full field 4D seismic monitoring strategy are presented, and a
supplement/alternative approach is introduced (Morgan et al., 2020) that capitalize on the key features
of CCS to calibrate flow models where and when needed with an agile focused seismic measurement.
