As part of pre-CO2 storage development plan assessment, geomechanical risk analysis is conducted on the field of interest to determine maximum injection pressure as well as the associated geomechanical risks during injection and long-term storage. In the analysis, first fully calibrated and validated 1D geomechanical models are developed from the available log data of the wells in the field of interest. Using the rock mechanical properties as input, caprock integrity analysis is conducted and maximum injection pressure is determined to ensure the caprock does not experience tensile or shear failure during CO2 injection. If there are faults penetrating the caprock and reservoir of interest, fault stability analysis is conducted on the faults to ensure the faults remain stable. Finally, reservoir expansion and seabed uplift analyses are conducted to determine the maximum surface uplift. The methodology is illustrated with examples from a CO2 storage field candidate located in offshore Peninsular Malaysia. Rock mechanical properties and stress data were extracted from the 1D geomechanical models at formation of interest for caprock integrity analysis to determine maximum injection pressure and for fault stability analysis to maintain stability of the faults. Seabed uplift was calculated for use in surface facility integrity evaluation.
