| Abstract |
The Wyoming CarbonSAFE project is aimed at storing more than 50 million metric tons of CO2 over 30 years in a stacked reservoir-caprock system. To alleviate the concerns of potential geomechanical risks associated with geologic carbon storage at the study site, a coupled fluid-flow and geomechanics simulation is conducted to evaluate the geomechanical effects resulting from CO2 injection. A field-scale reservoir model is constructed based on realistic reservoir characterization data including 3D seismic, well logs, core analysis and fluid samples. Both 1D and 3D mechanical earth models are constructed to characterize the rock's mechanical properties and in-situ stress state. It is observed that roughly 84 million metric tons of CO2 can be stored in the study site. The geomechanical analysis indicates that no failure happens for most of the reservoirs and their corresponding caprock, the basement faults remain stable, and a maximum uplift of 7.92 cm is observed at the surface. |
