Geomechanics contribution to CO storage containment and trapping mechanisms in tight sandstone complexes: A case study on Mae Moh Basin.

Recognized as a not-an-option approach to mitigate the climate crisis, carbon dioxide capture and storage (CCS) has a potential as much as gigaton of CO to sequestrate permanently and securely. Recent attention has been paid to store highly concentrated point-source CO into saline formation, of which Thailand considers one onshore case in the north located in Lampang - the Mae Moh coal-fired power plant matched with its own coal mine of Mae Moh Basin. Despite a large basin and short transport route from the source, target sandstone reservoir buried at deeper than 1000 m is of tight nature and limited data, while question on storing possibility has thereafter risen.
