文摘
- •
We model the thermal impact of CO2 injection on reservoir integrity.
- •
We develop a 3D thermo-geomechanical approach to evaluate the risk of reservoir fracture.
- •
Thermally induced fracturing is not expected for injection temperatures of 47 °C or higher.
- •
Lower injection temperatures about 28 °C could induce shear slip close to the wells.
