Abstract

This chapter evaluates a scheme of the leakage risk that is proposed with the scenarios based on the knowledge of geomechanics and experience in the petroleum industry. For gaining public acceptance, risk analysis on the leakage of stored CO2 in underground formations is not avoidable for geological sequestration program. However, the word "leakage" contains wide spectrum of possible risks and mechanisms. The occurrence and its mechanism are highly dependent on the geological conditions of storage structure, and uncertainties of them are great. The time range considered for this purpose covers years of injection operation to thousands of years of post shut-in period. Effects of the rapid gas release also have wide spectrum. Therefore, it is worth to makeup a framework of the risk evaluation with possible leakage scenarios that include paths of CO2, and leakage mechanism and conditions that cause the leakages, and also the effects of leakage. The probability and leakage volume should be evaluated with fully scientific manners in this framework.
