"Researchers recently investigate the feasibility of industrial-scale geological #CarbonSequestration as an effective #ClimateChange mitigation technology."

📜Details are discussed in a🧵⬇️

[1/9]

"This investigation was done by performing numerical simulations of coupled multiphase flow and geomechanics on a representative field-scale #geological model in the Gulf of Mexico that could become a typical CO2 #storage site."
2/9

Authors use "representative model to examine 2 potential hazards associated with large-scale CO2 storage:
🔸CO2 might migrate to shallower formations
🔸CO2 injection might induce seismicity due to destabilization of pre-existing faults."
3/9

"At study location, it is find that extensive distribution of clay minerals in fault zones in combination with large fault throws result in widespread occurrence of low-permeability faults that prevent migration of #CO2 outside of the #injection interval."
4/9

"Low-permeability faults act as flow barriers and can result in reservoir compartmentalization and pore pressure build-up."
5/9

"For the field-scale #geological model, researchers find that the risk of induced seismicity is controlled by the choice of the injection location with respect to pre-existing low-permeability faults."
6/9

"Results of the proposed model indicate that industrial-scale CO2
#storage in the Gulf of Mexico is feasible, but 𝑎 𝑝𝑟𝑖𝑜𝑟𝑖 reservoir characterization & injection location are essential to mitigate potential seismicity & CO2 migration to shallower formations."
