Decarbonization: Risk Analysis of CO2 Leakage
Important for evaluating safety! Analysis of the risk of CO2 leakage to the ground.
The risk analysis of CO2 leakage to the surface during and after CO2 injection is important for evaluating safety. It is necessary to examine the presence of faults and abandoned wells, as well as the appropriate injection pressure, and to conduct simulations that consider the impact not only on the reservoir but also on the cap rock. By coupling rock mechanics models with reservoir simulators, it is possible to perform calculations that take into account the effects of pressure changes on the geomechanical properties of the reservoir. For example, in GEM, a modified Barton-Bandis model is applied to simulate the opening and closing of fractures and calculate CO2 leakage from the cap rock. Our company is primarily investigating and examining the following items, focusing on calculations using the reservoir simulator GEM and literature research. [Investigation and Examination Items] ■ Examination of the workflow for creating simulation input data from experimental, analytical, and literature data. ■ Examination of the workflow for CO2 leakage risk analysis that reflects the uncertainty analysis of input data. ■ Investigation of the workflow for CO2 leakage calculations in various reservoir simulators. *For more details, please feel free to contact us.
