CO2 Mineralization in Basalts

03 February, 2022

The Arabian Plate Geology Group ( APG ) started in 2019 a research project to evaluate the potential for CO2 mineralization in basaltic rocks of Saudi Arabia, funded by Aramco’s Environmental Protection Department. 

The scope includes the Cenozoic Harrat volcanic fields (M Miliausha Petrova, M.S., 2021) and the Jizan Group volcanics (Jose Eduardo Torres, M.S, 2020, and Murtadha Al Malallah, M.S., 2021).  Postdoc Jakub Fedorik and his collaborators focused on fracture analysis of the Jizan volcanics, which is essential to build and simulate a fractured reservoir model by Professor Hussein Hoteit and his Group. 

This model will be used by Saudi Aramco for a pilot CO2 disposal well near Jizan Economic City. 

Visiting geologists examine the outcrop of the Jizan Group.

conduct dissolved CO2 in the formation and to provide a large surface area
for water-rock reactions.
