Probabilistic approach to evaluating seismicity in CO2 storage risk assessment

Abstract

Risk assessment has been employed in management tool kits in a wide variety of projects not necessarily related to CO2 storage. Studies suggest these approaches are applicable to CO2 storage. The features, events, and processes (FEP) that affect CO2 storage have been compiled in a database (Quintessa online). A methodology is proposed in this study which utilizes the FEP database and a probabilistic approach. It is illustrated by applying common geomechanical techniques to a case study conducted using an oil field in the Williston Basin. The implications of incorporating such assessments into a larger projectwide risk management plan are also discussed here.
