Abstract
Anthropogenic CO2 emissions rapidly increased during the post-industrial revolution causing global warming issues. In order to reduce the CO2 concentration in the atmosphere Carbon Capture and Sequestration will play a key transition role to transform into clean energy by utilizing the existing oil and gas infrastructure and subsurface data. The technology comes with certain challenges, amongst them, one of the real threats is the stored CO2 leakage back into the atmosphere and at shallower surfaces. This work talks about the understanding of geomechanical risks involved in the CCS process and probable ideas to mitigate the risks. CO2 injection leads to an increase in the pressure within the pores which eventually results in a change of stress and strain conditions within the reservoir. With a proper understanding of the reservoir and with a realistic field dataset a controlled injection can avoid a formation leading to geomechanical failures. Often field data are insufficient, in such a scenario this works talks about the preventive measures that can be adopted to avoid early mentioned calamity
