...&A) and development wells to ensure long-term viability of CO 2 sequestration projects. The complete paper evaluates well-integrity and CO 2 leakage risks along the wells in a depleted field that penetrates the CO 2 storage reservoir. Background The identified CO 2 storage site offshore Malaysia is a depleted...
