Integrated Characterization of the Faulted Caprock Shales of the Longyearbyen CO 2 Lab
The quantification of risk inherent to fluid leakage through faults and fractures remains a challenge for underground waste storage. Outcrop analogue studies provide quantitative information pertinent to sealing capacity and help constrain fluid migration modelling and risk assessment. We present an...

The quantification of risk inherent to fluid leakage through faults and fractures remains a challenge for underground waste storage.
